Holding tank level indicators can help us monitor and control liquid levels. Whether it is a fuel tank on a truck, a fire water storage tank, an underground sewage storage tank, or even a marine storage tank, etc. Replacing manual inspection with automated Level Monitoring System can be faster and more accurate.

Level Monitoring System for Industrial Holding Tanks

Disassemble the system

Before setting up a Level Monitoring System for Industrial Holding Tanks, we need to first understand what should be included in the system.
Based on our many years of experience in level monitoring services at Sino-Inst, we have simplified the entire system from complexity. Simply put, the system can be divided into two parts: Level sensor + Tank level Monitor.

These two parts are both independent and interrelated. You can choose different types of level sensors and Tank level Monitors according to actual needs. Then use the connection key, which is our signal output (such as RS485, 4-20mA) to make them work synchronously.

Exploring Advanced Level Monitoring Technologies

Part 1: Level Sensor

We have analyzed the working principles, advantages and disadvantages of various level sensors in detail in our previous blog. You can learn more about it. Here, we briefly introduce a few commonly used ones:

  • External ultrasonic level sensor: It can be simply pasted on the bottom of the tank for liquid level measurement. Suitable for tanks less than 2 meters. Like a truck fuel tank.
  • Capacitive level sensor: suitable for liquid level measurement under various special conditions such as high pressure, high temperature, extremely low temperature, etc.
  • Ultrasonic level sensor: low-cost non-contact measurement. You can choose anti-corrosion and explosion-proof materials.
  • Radar level sensor: wider application range. High measurement accuracy. Can be applied to tanks with a measuring range of 30m.
  • Magnetostrictive level sensor: the most accurate level sensor. Can be customized as an oil level interface sensor. It can also be customized to measure temperature at the same time.
  • Hydrostatic pressure level sensor: enables low-cost, large-range measurement.
  • Float level sensor: The measurement principle is the simplest.

Part 2: Monitor System

We generally configure paperless liquid level recorders for users to measure and record on-site liquid level signals. It can even perform alarm, signal output, printing and other functions according to user needs.

Monitor system

For example, some of our common models:

7620/7620R Series LCD Volume Display Regulator/ Recorder is specifically designed for industrial on-site regular and irregular canned liquid, volume and mass conversion.

The device has empowered by the surface mounting technology, featuring the design of multiple-layered protection and isolation, with a strong anti-interference capability and high reliability. It has used the embedded operating system with USB data dump function. The data storage time could reach up to 720 days. By using U disk and host computer analysis software, one could call and view the historic curve of process variants and relevant historic data from time to time. It also could match with various liquid sensors, such as ultrasonic liquid level meter. The device has sound anti-theft and anti-damage and other features.

T710 series 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.

Universal input of NHR-8100/8700 series color paperless recorder (capable of inputting by means of configuration: standard voltage, standard current, thermocouple, thermal resistance, millivolt, etc.). It can be equipped with 18-channel alarm output or 12 -channel analog transmitting output, RS232/485 communication interface, Ethernet interface, mini-printer interface, USB interface and SD card socket; can provide sensor distribution; is equipped with powerful display function, real-time curve display, historical curve retrospection, bar graph display, alarm list display, etc. The meter is of high cost effectiveness due to its humanized design, perfect function, reliable hardware quality and exquisite craftsmanship.

Other requirements support customization.

Steps to quickly build an industrial holding tank level indicator

Let’s say you only have the tank now. There is no liquid level sensor or system.

Understand the basic parameters of the tank. For example, the shape, height, width, wall thickness, pressure, and temperature of the tank. Is there stirring inside the tank?

  • Understand the condition of the media. Is the medium corrosive? Will there be evaporation?
  • Be clear about your needs. For example: You want to achieve synchronous detection of liquid levels in 6 storage tanks.
  • Choose appropriate level sensors and tank level monitors. Make purchases based on the parameters and needs you have mastered above.
  • Install the liquid level sensor. (For specific installation steps and installation details, refer to the manufacturer’s recommendations)
  • Signal connection. Output the signal line of the level sensor to the Tank level Monitor system. For example, the access of 4-20mA signal line.
  • Calibration and testing. After setup and testing, you can easily monitor the liquid level of industrial holding tanks.

If you already have a holding tank level sensor, just select the applicable level monitors based on the output signals supported by the level sensor.

More Level Measurement Solutions

We at Sino-Inst are professional suppliers of holding tank level indicators. Our level sensors and level monitoring systems are widely used in various industries. For example, it can be used as sewage holding tank level indicator or marine holding tank level indicator.

In addition to supplying holding tank level indicators for tanks, we also provide pressure and temperature measurement solutions for various tanks. Including measurements under extreme conditions such as explosion-proof, anti-corrosion, high temperature, extremely low temperature, etc. There are also flow meters that can be used to monitor the flow of tank media filling pipes.
