Underground tanks refer to tanks installed below the ground for storing gas or liquid. So is measuring the level of an underground tank the same as measuring the level of a tank above ground? The answer is no. Most underground tanks come pre-assembled. Once installed, it will not change year after year. The most common ones are underground oil storage tanks at gas stations.

So how to measure the liquid level of underground tanks? What tank level indicators are available? Let’s take a look together.

RFQ

Underground tanks are generally installed pre-buried. After installation, it is difficult to make changes to the bottom, sides, etc. of the tank. Of course, underground tanks generally have reserved manholes, feed openings, discharge openings, etc. Some will also reserve installation locations specifically for level meters.

Based on our experience, underground tank level indicators can be divided into two categories: contact and non-contact. For example, ultrasonic level meter and radar level meter are commonly used non-contact level indicators. For example, Hydrostatic Level Sensor, float level sensor, and magnetostrictive level meter are commonly used contact level indicators.

The specific choice needs to be determined based on the conditions of the medium in the storage tank. The second half of our blog will explain this with examples.

Below are the various underground tank level indicators we supply at Sino-Inst. You can choose to delve deeper into the measurement parameters:

Available underground tanks level indicators

OK Next, we will use our actual cases to hand over the choice of underground tank level indicators for you.

Gas station underground oil storage tanks

We all know that most diesel and gasoline at gas stations are stored in underground tanks. The oil level needs to be accurately monitored in real time. Including when feeding and discharging materials. The accuracy of this tank level indicator needs to be very high. Because it is directly linked to money.

So based on our experience, in this case we would recommend users to choose Magnetostrictive liquid level sensor.

Mainly because Magnetostrictive liquid level sensor can meet the following characteristics:

1. Large range: 0.2m～25m;
2. Meet the explosion-proof requirements of gas stations. Explosion-proof level: ExdⅡCT6 Gb;
3. High precision. Magnetostrictive level transmitter has a maximum accuracy of 1mm;
4. Can meet high temperature, high pressure and other parameter customization. -40 ℃ ~ +350 ℃, 10MPa;
5. The installation size can be customized. According to the installation requirements of underground oil storage tanks, threaded or flange installation can be configured.
6. Support signal output, 4~20mA, 0~5V, 0~10V, HART, RS-485. It is convenient for real-time monitoring of oil level in the office.
7. The Magnetostrictive level transmitter can also be customized according to needs: interface output (measurement of oil-water interface), and simultaneous output of temperature and liquid level (up to 8 RTD temperature sensors can be installed for temperature detection).

Chemical corrosive raw material storage tanks

The capacity of underground storage tanks in the chemical industry can range from thousands to millions of gallons. For example, some large chemical plants may have underground storage tanks with a capacity of 300,000 gallons for storing raw materials such as ethylene and benzene.

This type of Underground Tanks level measurement will be more complicated than the above two. We need to comprehensively consider many factors, especially the characteristics of the medium:

1. The size and shape of the tank.
2. The temperature, pressure, viscosity, corrosiveness, etc. of the medium.
3. Is there stirring in the tank?
4. The installation position of the inlet and outlet, etc.;

Here we discuss the level indicators available for corrosive media. Generally there are radar level meters and guided wave radar level meters. Or customize an anti-corrosion input level sensor made of PTFE.

The following is also a case of measurement by one of our customers. The measuring medium is: a metal tank containing 98% sulfuric acid. The tank is large and comes with a picture of the level transmitter installed.

Marine Water Tank Level Sensors have always been an important part of the marine tank monitoring system. There are many places on ships where water levels need to be detected. Such as fuel, fresh water and sewage storage tanks. The liquids in these tanks are a critical resource for ship operations and require constant monitoring to ensure supply and appropriate storage. For example, the water level in the water storage tanks and pipelines of the fire protection system also needs to be monitored to ensure that there is sufficient water supply in an emergency. Even equipment that handles seawater, sewage or other waste liquids needs to monitor water levels to ensure proper operation of the equipment.

RFQ

What are Marine Water Tank Level Sensors?

Marine Water Tank Level Sensors are specially designed to measure the water level inside ships. For example, in fresh and drinking water as well as gray water or waste water storage tanks on ships, Marine Water Tank Level Sensors can detect liquid levels from very low to very high.

Marine Water Tank Level Sensors generally use capacitive, hydrostatic, or radar measurement technologies. Convert the water level into an analog signal and then transmit it to the marine tank monitoring system. To effectively monitor, record and control the liquid level in the tank. And the sensors are often used in conjunction with alarm systems to alert users when the level in the tank reaches a certain level.

marine tank monitoring system

Marine Tank Monitoring System is a system used on ships to monitor the liquid levels of various storage tanks (such as oil, fresh water, sewage, etc.) in real time. It is an important part of ensuring the safe and efficient operation of ships.

In addition to monitoring water levels, other liquid levels also need to be monitored on ships. The installation of liquid level measurement and alarm systems on oil tankers and chemical ships is to monitor cargo tanks and other oil and water tanks. On the one hand, by measuring the liquid level, the crew can keep track of the various conditions of the ship during navigation to ensure the best loading of the ship. More importantly, it is to prevent the liquid level from being too high and causing overflow. To avoid causing fires and contaminating the surrounding marine environment.

The following are some basic features and components of the system:

• Function:
  • Monitor the liquid level in the storage tank in real time.
  • Record and analyze liquid level data.
  • Sounds an alarm when the liquid level exceeds the preset range.
  • Sometimes other parameters such as temperature and pressure of the storage tank can also be monitored.
• Sensor:
  • The liquid level sensor is the core component and can be float type, capacitive type, radar type, pressure type, etc.
  • As needed, it may also include temperature sensors, pressure sensors, etc.
• Display and control terminal:
  • Usually located in the control room or bridge of the ship, it is used to display the liquid level information of each storage tank in real time.
  • Allows operators to set alarm thresholds, view historical data, and more.
• Correspondence:
  • Communication is required between the sensors and control terminals within the system, which may be wired (such as RS485, Ethernet) or wireless.
  • In more advanced systems, remote monitoring capabilities may also be provided, allowing a land-based management center or other vessel to obtain data in real time.
• Data processing and storage:
  • Systems will typically include a data processing unit to receive, process and store data collected from sensors.
  • Facilitate subsequent analysis, statistics and reporting.
• Power and backup:
  • Considering the particularity of ship power supply, the system usually has its own power module with battery backup to ensure that it can still work normally in the event of a short-term power interruption.
• Alarm function:
  • When the liquid level exceeds the preset safety range, the system will automatically send out an audible and visual alarm to remind the operator to handle it in time.

RFQ

So which High temperature level sensor should you choose? This needs to be chosen based on your actual measurement parameters. Next, let’s analyze it together.

Featured High Temperature Level Sensors

Different types of high temperature level sensors

There are many types of level sensors. Different types of liquid level gauges can withstand different temperatures. In order to save you time in purchasing, we have compiled here the high temperature parameters that various level meters can withstand.

Of course, this summary is mainly based on the high-temperature level sensors produced and supplied by our Sino-Inst. The level sensor types and temperature parameters provided by other manufacturers are not necessarily the same.

Liquid level measurement under high temperature conditions is nothing more than three solutions.
The first is the replacement of materials.
The second is to add cooling structural parts.
The third is to add cooling assistance, such as water, liquid nitrogen, etc.

If you need to measure high-temperature liquid level and don’t know which level sensor to choose, you can contact our sales engineers for consultation.

High temperature water level measurement

The temperature of water, the boiling point of water at standard atmospheric pressure is 100°C. However, at higher pressures, such as in a pressure cooker or industrial boiler, the boiling point of water increases. In fact, under very high pressure environments, water can exist in a liquid state up to 374°C, which is its critical temperature. So while water has a standard boiling point of 100°C at 1 atmosphere of pressure, it can exist at higher temperatures at elevated pressures.

Accurate measurement of water levels under high temperature conditions is critical across multiple industries and applications. For example, power plants, geothermal energy production, industrial processes, and HVAC systems in large commercial buildings all require water level measurement at high temperatures. In order to meet this demand, a variety of liquid level sensors suitable for high-temperature environments are available on the market, such as ultrasonic sensors, capacitive sensors, and hydrostatic pressure sensors. Different sensors vary in the temperature range they can handle.

High temperature Oil level measurement

High-temperature oils are widely used in many industrial fields. From automotive manufacturing and oil and gas extraction to food processing and chemical industries, accurate measurement of oil levels is required.

In the automotive and aircraft industries, for example, high-temperature oils are used to lubricate and cool engines, transmissions and turbines.

In the oil and gas industry, high temperature oil levels need to be measured and monitored during refining and processing.

In food processing, high-temperature oils are often used for cooking and processing of food.

Commonly used liquid level measurement techniques:

• Radar (guided wave) sensor: Measures oil level by using electromagnetic waves. Suitable for high temperature and high pressure environments, for example, it can handle temperatures from 80°C to 450°C. Even higher temperatures can be customized.
• Hydrostatic Pressure Sensor: Measures fluid level based on the pressure generated by the oil column, ideal for closed tanks and containers.
• Capacitive Sensor: Measures oil level by detecting changes in capacity and can handle temperatures from 80°C to 250°C.
• Magnetostrictive level transmitter: -40°C-320°C, measurement accuracy can be as high as 0.01% FS.

When selecting a sensor suitable for high temperature oil level measurement, it is important to consider the actual application requirements such as temperature, pressure and oil properties, as well as the accuracy and reliability of the sensor.

High temperature Tank level measurement

Large tanks for storing and handling high-temperature liquids are common in numerous industrial sectors. These liquids may be petroleum, chemicals or other industrial feedstocks that require storage at high temperatures during production. Therefore, it becomes critical to accurately and reliably measure the level of these tanks.

Why is high temperature storage tank level measurement so critical?

Safety factors: High-temperature liquids may be flammable and may also be harmful to humans. Therefore, it is crucial to ensure that liquids do not spill or leak.
Economic benefits: Accurate liquid level measurement can ensure the continuity of the production process, avoid resource waste, and improve efficiency.

Then the liquid level measurement of high-temperature storage tanks is also more complicated. When selecting a suitable level measurement technology, a number of factors must be considered. Including the properties of the liquid, tank design, temperature and pressure, etc. It is important to ensure that the chosen technology provides accurate, reliable data and ensures the safety of personnel during all operations.

In high-temperature storage tank liquid level measurement, more people will choose: high-temperature radar, high-temperature guided wave radar, capacitance, magnetostriction, or differential pressure level meter.

In fact, many times, whether our level sensors can meet the liquid level measurement under high temperature will also be related to the pressure. For example, for radar level meters, high temperature measurement and high pressure measurement cannot be satisfied at the same time. Therefore, when you pay attention to your measured temperature, you also need to pay attention to the measured pressure. We at Sino-Inst, as a professional measurement supplier, also have pressure transmitters that meet high temperature measurement for you to choose from.

Industrial applications of high temperature level sensors

High temperature liquid level sensors have a wide range of applications in industry. Here are some typical industrial application scenarios involving high-temperature fluids or materials:

1. Condensation tower: In the petroleum and chemical industries, condensation towers are used to cool and condense high-temperature gases. Accurate measurement of liquid levels in these towers ensures process continuity and prevents overfilling.
2. High-temperature molten salt: In solar heat collection and energy storage systems, high-temperature molten salt serves as the heat storage medium. Level sensors ensure that the molten salt is maintained at the proper level as it collects and releases heat.
3. High temperature aluminum liquid: In the smelting plant, liquid aluminum flows and is stored at high temperature. The use of high-temperature liquid level sensors can accurately measure the liquid level of liquid metal to ensure the stability of the casting process.
4. Molten glass: In glass manufacturing, raw materials are heated to extremely high temperatures until they melt. Accurate liquid level measurement is critical for glass molding and production.
5. High-temperature boilers: In the field of energy and power generation, water in high-temperature boilers needs to be heated under high pressure. A level sensor ensures that the water level does not get too low, preventing the boiler from overheating.
6. Chemical reactor: In some chemical processes, liquid reactants need to be heated at high temperatures. Accurately measuring the liquid levels in these reactors ensures the continuity and stability of chemical reactions.

More Level Measurement Solutions

Cooling Tower Level Sensors refer to a type of level meter that can be used to measure the water level of cooling towers. Cooling Tower Level Sensors are an important part of the cooling tower’s cooling function. The cooling tower liquid level control system is mainly used to control the cooling water level in the cooling tower to maintain it within a reasonable range at all times. And it can realize real-time monitoring of liquid level and abnormal alarm function. To ensure that it will not cause high temperature failure or damage to the air compressor.

RFQ

Cooling Tower Water Basins

A cooling tower is a heat exchange system that brings air and water into direct contact to lower the water temperature.

To achieve this, water is continuously pumped to the top of the tower. There it flows through a series of baffles, mixing with air. And collected in the pool directly below the tower or the sump next to the tower. As heat and water escape from the tower through evaporation, additional water must be added to the system periodically.

Cooling towers come in many sizes, from rooftop systems to building size and beyond. A typical birdbath is open to the air and has a depth of 4 feet or less. Made of fiberglass, metal or concrete. The capacity is large enough to hold all the water in the system.

Cooling towers have two basic control systems, one for adding liquid to the pool. The other is used to turn the water recirculation system on or off. The main requirements of this application are to monitor the fluid level, automatically fill the basin and prevent the system from drying out.

At present, cooling towers generally use packed towers. If the tower liquid level is too high, it may easily cause:

1. The dehydration effect of the cooling tower is not good;
2. System pressure fluctuation increases;
3. The porcelain ring in the tower is easily broken;
4. Increase the workload of each water outlet.

Cooling tower water level monitoring and control system

If there is a new cooling tower now. A water level monitoring and control system needs to be established. The following design points can be considered. This is all based on our Sino-Inst’s years of experience in providing liquid level measurement services.

• Identify goals and needs:
  • Do you only need to monitor the liquid level, or do you also need to control the liquid level?
  • What are your liquid level accuracy needs?
  • Are there special temperature, pressure or fluid property requirements?
• Choose the right Cooling Tower Level sensor:
  • Based on the previous discussion, you might choose ultrasonic, Hydrostatic, or capacitive sensors as they are suitable for a wide range of applications and provide continuous level measurement. We discuss these techniques in detail below.
• Installation location:
  • Ensure the sensor is optimally positioned to accurately measure the entire liquid level range.
• Output and communication:
  • Choose a sensor with a standard output (e.g. 4-20 mA) that can be easily integrated into existing control systems.
  • Consider using modern communication protocols such as Modbus or HART for remote access and debugging.
• Level Control:
  • If level control is required, you may choose to use a solenoid valve or pump to increase or decrease the liquid.
  • Controllers can automatically turn these devices on or off based on set points, ensuring liquid levels remain within the desired range.
• Security and Alarm:
  • Set high and low level alarms to prevent the system from overloading or drying out.
  • Consider using a redundant system to ensure backup level measurement in the event of a primary system failure.
• System verification and calibration:
  • After the system is started, a full range of liquid level measurements are taken to ensure that all components are functioning properly.
  • Calibrate the sensor regularly to ensure measurement accuracy.
• Maintenance and monitoring:
  • Check all equipment regularly to ensure there is no wear or damage.
  • Consider using a remote monitoring system to check fluid levels and system status from any location.

Hopefully this blueprint will provide a good starting point for your cooling tower level monitoring and control system. If you have any specific questions or need further guidance, please let me know!

Implement cooling tower level control

After choosing the appropriate Cooling tower level sensors. We need to set up the cooling tower water level control.

The control of cooling tower water level is a key link to ensure the stable operation of cooling tower. The correct water level ensures cooling efficiency while also avoiding equipment downtime due to lack of water. The following is an introduction and guidance on how to achieve cooling tower water level control:

Connect and control equipment:

Cooling Tower Level sensors typically output a 4-20 mA current signal, which can be connected to a local controller or central control system. These control devices can be PLC, SCADA, DSC or independent level controllers. Any control device will do as long as the device can accept a 4-20 mA current signal.

Configuration operation scope:

The operating range of the controller needs to be programmed according to the measurement span of the Cooling Tower level sensor. Also, consider that the sensor’s 4 mA set point is typically above empty box conditions. Once the controller’s operating range and engineering units are configured correctly, they can be applied to relay set points for pumps, valves, or alarm automation.

Critical control points:

The main control task is to ensure that the cooling tower is filled in time before the water is reduced due to evaporation. This avoids process interruptions due to lack of water. Typically, this is accomplished via a valve. The filling process should start at a low level and stop at a high level.

Set alarm point:

• A low level alarm or shutdown set point should be set below the open valve set point to ensure filling begins before the low level reaches this point.
• For safety reasons, it is recommended to use an independent high level alarm or safety shutdown system in addition to the main control system.
• Likewise, for process protection it is recommended to use an independent low level alarm or safety shutdown system.

The PLC, SCADA, DSC or independent level controllers mentioned above need to be provided by professional suppliers. If you do not have these systems and want to achieve control, you can use the level recorders provided by Sino-Inst.

The T710 series ultrathin paperless recorder adopts the new large-scale integrated circuits to realize the reliable protection and robust anti-jamming for input, output, power supply and signals. The recorder can achieve eight-channel universal signal input (the configurable and optional inputs include standard voltage, standard current, thermocouple, thermal resistance and millivolt), four-channel alarm output and one feed output. It has the RS485 communication port, Ethernet port, micro-printer port, USB device port and SD card socket. The recorder enjoys a powerful display function, which can achieve real-time graphic display, historical graphic recalling, bar graph display and alarm status display.
