Importance of Sea Water Flow Measurement

Seawater stores 96.54% of the earth’s fresh water, which contains a huge amount of minerals, energy and other resources. The current forms of seawater resources development and utilization mainly include: seawater desalination, direct utilization of seawater and utilization of seawater chemical resources.

In seawater desalination

In coastal cities and islands where water resources are seriously short. Mainly large-scale industrial seawater desalination projects. Mainly concentrated in high water consumption industries such as electric power and steel. Seawater desalination projects for islands used in offshore cities.

In terms of direct use of seawater

Mainly for seawater cooling applications. Among them, seawater DC cooling technology is mature and is mainly used in coastal thermal power, nuclear power, petrochemical, steel and other industries. Seawater circulating cooling technology has been gradually applied in the coastal power industry.

In the utilization of seawater chemical resources

It mainly includes salt production from seawater, potassium extraction from seawater, bromine extraction from seawater, magnesium extraction from seawater, etc. In addition to seawater salt production, the main products include bromine, potassium chloride, magnesium chloride, magnesium sulfate, and potassium sulfate.

Therefore, the utilization rate of seawater is getting higher and higher. Even in the future, people will find more favorable treatment and utilization of seawater. Among them, flow measurement before and after seawater treatment, or flow measurement before and after seawater use will become more and more important.

Difficulties in sea water measurement

Seawater is a highly corrosive fluid. Seawater is a very complex multi-component aqueous solution, which contains various ions such as sodium, potassium, calcium, magnesium, copper, zinc, manganese, etc. Its salt content is very high and it is highly corrosive.

Simultaneously, waves and tides create low-frequency mutual stress and impact metal parts. Marine microorganisms, attached organisms and their metabolites also produce direct or indirect accelerated corrosion processes.

Marine corrosion is mainly localized corrosion, which starts at the surface of the component and occurs in a small area. Examples include galvanic corrosion, pitting and crevice corrosion.

Therefore, it is very necessary to consider corrosion issues when selecting seawater flowmeter sensors.

Magnetic flowmeter to measure sea water

Electromagnetic flow is the preferred flowmeter for measuring the volume flow of liquids with a certain conductivity.
Electromagnetic flowmeter is a flow measuring instrument that works based on the principle of electromagnetic induction. It consists of sensors and transmitters.

Advantages

1. There are no moving parts and bluff bodies in the measuring conduit. Therefore, the pressure loss is very small, and there is no mechanical inertia, so the response is sensitive;
2. Wide measurable range: the turndown ratio is generally 10:1, up to 100:1. The flow velocity range is generally 1-6m/s, and can be extended to 0.5-10m/s. The flow range can be from 90mL/h to hundreds of thousands of m3/h. Pipe diameters can range from 2mm to 2400mm or 3000mm.
3. It can measure the volume flow of liquids containing solid particles, suspended matter, or acids, alkalis, and salt solutions with certain conductivity. It can also measure pulsating flow, and can carry out two-way measurement.
4. There is a linear relationship between the flow signal and the fluid volume flow, so the meter has a uniform scale. And the volume flow rate of the fluid has nothing to do with the physical properties and flow state of the medium. Therefore, the electromagnetic flowmeter only needs to be calibrated with water, and it can be used to measure the volume flow of other conductive liquids without correction.
5. Compared with most other flow meters, the requirements for the front straight pipe section are lower.

Disadvantages

1. The temperature and pressure should not be too high;
2. The scope of application is limited. It cannot be used to measure the flow of non-conductive fluids such as gas, steam and petroleum products, and fluids containing more and larger bubbles;
3. When the flow rate and velocity distribution do not meet the set conditions, large measurement errors will occur;
4. When the flow rate is too low, it is difficult to amplify and measure the induced potential of the order of magnitude opposite to the interference signal. And the instrument is also prone to zero drift;
5. The signal of the electromagnetic flowmeter is relatively weak. A little interference from the outside world can affect the accuracy of the measurement.

ultrasonic flowmeter to measure sea water

Ultrasonic flowmeters are instruments that measure volume flow by detecting the action of ultrasonic beams (or ultrasonic pulses) when fluid flows.

The sound wave propagates in the fluid, and the sound wave propagation speed will increase in the downstream direction. , the countercurrent direction decreases, and the same propagation distance has different propagation times. The propagation time method is to calculate the flow velocity by using the relationship between the difference of the propagation velocity and the flow velocity of the measured liquid. Combined with the pipe diameter to obtain the flow rate.

Advantages

1. Ultrasonic flowmeter can be used for non-contact measurement. The clip-on transducer ultrasonic flowmeter can be installed without stopping the flow-carrying tube. Just install the transducer outside the pipeline to be tested. That is, the flow can be measured with an ultrasonic flowmeter on existing pipelines that cannot be cut off or drilled;
2. Ultrasonic flowmeters measure without flow obstruction. No additional pressure loss;
3. The instrument factor of the measuring meter can be calculated from the geometric dimensions of the actual measurement pipe and sound channel. The dry method can be used for calibration. Except for the type with measuring pipe section, it generally does not need to do real flow calibration;
4. Ultrasonic flow meters are suitable for large round and rectangular pipes. And it is not limited by pipe diameter in principle. Its cost basically has nothing to do with the pipe diameter;
5. Doppler ultrasonic flowmeters can measure liquids with high solid content or bubbles.

More about: Insertion Type Ultrasonic Flow Meter Applications

Disadvantages

1. The ultrasonic flowmeter in the propagation time method can only be used for clean liquids and gases, and cannot measure liquids with suspended particles and air bubbles exceeding a certain range. On the contrary, the Doppler method LSF can only be used to measure liquids containing certain heterogeneous phases;
2. Ultrasonic flowmeters with external transducers cannot be used in lined or heavily scaled pipes. And it cannot be used for stripping the lining (or rust layer) from the inner pipe. If there is gas in the interlayer, the ultrasonic signal will be seriously attenuated. Or pipes with severe corrosion (changing the ultrasonic path);
3. In most cases, the Doppler method ultrasonic flowmeter has a low measurement rate;
4. It cannot be used for pipes with a diameter smaller than DN15mm.

conclusion

So, which flow meter should you choose for Sea Water Flow Measurement or salt water flow?
We believe that:

1. If the seawater concentration is low and the salinity is small.

Then ultrasonic flowmeter is a better choice. Such flow meters do not require contact with seawater and avoid corrosion.
At the same time, its flow sensor is not a metal part and is not afraid of corrosive materials.

For this type of seawater, if you choose an electromagnetic flowmeter. Then a 316L stainless steel electrode and rubber lining material should work well.

2. If the seawater has high concentration and high salinity.

Then the external clamp ultrasonic flowmeter is a better solution.

If you want to choose an online electromagnetic flowmeter for better performance. The best choice is Hastelloy C electrode and PTFE lining material. Hastelloy C electrodes are suitable for oxidation of salts such as Fe++, Cu++ and seawater.

3. For seawater desalination projects, plastic pipes are mainly used as water delivery equipment.

Many pipes are in the air. If an in-line electromagnetic flowmeter is used, the electromagnetic flowmeter is heavy. And the plastic tube doesn’t hold it in place very well. As a result, support brackets have to be installed, which adds a lot of cost and inconvenience.

Therefore, we recommend using a transit-time ultrasonic water flow meter. No pipe cutting required, light weight, easy installation, no maintenance etc.

4. If it is to measure the pipeline above DN3000.

Then the external clamp ultrasonic flowmeter is a better choice. For large diameter pipes, clamp-on ultrasonic flowmeters are less costly.

The working principle of High Pressure Rotameter:

The high-pressure metal tube rotameter is the force that the upper and lower ends of the float generate differential pressure to form a rising force when the measured medium passes through the conical measuring tube from bottom to top.

When the lifting force on the float is greater than the weight of the float immersed in the fluid, the float will rise. The area of ​​the annulus will increase accordingly. The fluid velocity at the annulus will drop immediately. The differential pressure at the upper and lower ends of the float will decrease. The float is stabilized at a certain height until the lift force is equal to the weight of the float immersed in the fluid.

The height of the float position corresponds to the flow rate of the measured medium.

The float has a built-in magnet. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.

a. For the local type, the rotating magnet in the local indicator is coupled with the magnetic steel in the float to rotate. At the same time, the pointer is driven to indicate the flow rate at this time through the dial.

b. For the intelligent type, the change of the magnetic field is converted into an electrical signal by a solid-state magnetic sensor in the intelligent indicator. After A/D conversion, microprocessor. D/A output, LCD liquid crystal display, to display the flow rate size and cumulative flow.

What Is Difference Between Rotameter and Flow Meter?

A rotameter is a device that measures the flow rate of liquid or gas in a closed system. It consists of a float that moves up and down in a tube, based on the fluid’s flow rate. The faster the fluid flows, the higher the float rises.

A flowmeter is a device that measures the volume of liquid or gas that flows through it. There are many different types of flowmeters, each designed to measure different types of fluids. For example, positive displacement flowmeters measure the volume of fluid that passes through them, while rotameters measure the rate of flow.

Featured Mechanical Diesel Flow Meters

Characteristics of Diesel Flow

Diesel is a kind of light petroleum, which belongs to the fuel of diesel engine. The use of high-speed diesel engines on cars is more fuel-efficient than gasoline engines.

Diesel demand is growing faster than gasoline. Diesel engines have higher thermal efficiency and higher power than gasoline engines. The fuel consumption per unit is low and relatively economical, so the application is increasing day by day. In many occasions, it needs to be measured.

For oil tanker or diesel storage tank pipeline transportation, it is more suitable to choose a flowmeter with higher measurement accuracy. Because it is not only convenient for trade settlement, but also high precision. The measurement is accurate and can be used for a long time.

According to the role of diesel: the use can be divided into marine diesel engine, locomotive diesel engine, automobile diesel engine, power generation diesel engine, agricultural diesel engine, construction machinery diesel engine, etc.

Diesel Fuel: Diesel fuel is primarily diesel. Light diesel oil is usually used for high-speed diesel engines. Light diesel or heavy diesel for medium and low speed diesel engines.

Mechanical Diesel Flow Meter Working Principle

Oval gear flow meters are our most commonly used Mechanical Diesel Flow Meters.

The oval gear flowmeter is composed of a metering box and a pair of elliptical gears installed in the metering box, and the upper and lower cover plates form a sealed crescent-shaped cavity (due to the rotation of the gear, it is not sealed) as the calculation unit of a displacement .

The flow meter is mainly composed of a housing, a counter, an elliptical gear, and a coupling (magnetic coupling and axial coupling), etc. As shown in the figure.

1.Counter 2. Transmitter

3. Accuracy adjuster (used above DN50)

4. Sealed coupling

5. Front cover 6. Cover plate

7. Oval gear 8. Shell

9. Rear cover

When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet pushes a pair of gears to continuously rotate, and the liquid measured by the crescent-shaped cavity is continuously transported to the outlet. The product of four times the secondary displacement is the total amount of the measured liquid flow.

The elliptical gear generates a torque to make it rotate under the action of the pressure difference △p of the measured medium.

The rotor 1 and the rotor 2 are alternately driven by one to rotate the other. There are two magnets on each rotor as signal generating elements. There is a magnetic signal detecting element at the center of the two axes at the bottom of the cavity. Whenever the magnet turns to the detecting element, the sensor counts as a pulse.

Each pulse corresponds to a certain amount of medium discharge F, F=XXml/p, so the volume flow Qm per unit time can be obtained: Qm=F*H, F is the amount of medium removed by each pulse; H pulse per unit time number.

Metal Tube Flow Meter-Variable Area Flow Meters Principle

A Metal Tube Flow Meter is a variable area flow meter. It consists of measuring tube, float, indicator, process connection, and so on.

Rotameter flow meter working principle

When the measured fluid passes through the annulus formed by the cone and floats from the bottom to top.

The differential pressure produced at the upper and lower ends of the float forms the force for the float to rise.

When the rise of the float is greater than the weight of the float immersed in the fluid. The float rises.

The annulus area increases accordingly. The fluid velocity in the annulus drops immediately.

The differential pressure at the upper and lower ends of the float is reduced. The lifting force acting on the float also decreases.

Until the rising force equals the weight of the float immersed in the fluid, the float will stabilize at a certain height.

The height of the float in the tapered tube and the flow rate through it correspond to each other.

What is LORA Smart Water Meter?

With the development of the Internet of Things technology, the “members” of the water meter family have undergone various changes. The new LORA smart water meter is favored by large water companies with spread spectrum modulation technology.

Presumably everyone is very unfamiliar with the word “LORA” in the Lora smart water meter. “LORA” stands for long-distance low-power data transmission, and it is a patented technology of a company in the United States. It uses chirp spread spectrum modulation technology and requires no wiring. A SIM card is added inside the concentrator host to realize wireless remote data transmission. Its receiving sensitivity has reached an astonishing -148dbm.

Compared with other advanced level chips in the industry. The higher receiving sensitivity improves more than 20db, which ensures the reliability of network connection.

Compared with other ordinary smart water meters, LORA smart water meters have the advantages of strong anti-interference, strong signal reception, low power consumption, and no wiring. Completely beats other ordinary smart water meters. It must be the trend of water meter products in the future.

Wireless Remote LORA Water Meter vs Mechanical Water Meter

With the continuous update of intelligent remote transmission technology, traditional mechanical water meters have been hit unprecedentedly in the industry. Will mechanical water meters be replaced by new smart water meters? Then we have to see which of their respective performance can better meet the market demand.

Let’s take the current popular LORA wireless remote water meter as an example to compare it with ordinary mechanical water meters.

The most prominent drawback of ordinary mechanical water meters is its meter reading method, and the impact of this drawback is becoming increasingly prominent.

In our inherent thinking, it is a very common and normal thing for meter readers to go door-to-door to read meters. However, under the impact of technologies such as the Internet of Things, the efficiency of door-to-door meter reading has been questioned.

The LORA wireless remote water meter developed using new technology is a meter reading command issued by the meter reader through the remote meter reading system. After the LORA module on the wireless remote water meter receives the meter reading command, it will The data is uploaded to the server. The meter reader can read the water meter data. This avoids the high cost and low efficiency of manual meter reading and the nuisance problems caused by household meter reading.

No matter what kind of water meter and what kind of function it has, they are all born to serve people’s lives. Whoever can provide more convenience and higher efficiency will be pushed to the stage of history.
