At present, each enterprise most of sewage flow meter adopts the electromagnetic flowmeter, it is a kind of speed type water meter, is by Faraday.

More flow meter manufacturers choose model price quote you are welcome to inquire, here is the cause of abnormality of sewage flow meter scale and measures for solving the article details.

Abnormal reasons and solutions of sewage flowmeter: sewage flowmeter is a kind of measuring the pipe flow accumulative volume measuring instruments.

At present, each enterprise most of sewage flow meter adopts the electromagnetic flowmeter, it is a kind of speed type water meter, is by Faraday's law of electromagnetic induction principle.

Flowmeter measurement abnormal phenomenon and for various reasons, here I will combine the work actual from water supply pipe network and to analyze the characteristics of the flow meter itself mainly exist the following phenomena and reason: phenomenon 1: many users of water meter in water have a slow rotation phenomenon.

Performance in the presence of water meter initiating pointer stop walking, sometimes into three circle a circle, back in the water this kind of phenomenon is more obvious during the rush hours, we call it a water meter rotation phenomenon.
The reason (
1)

: the water pressure fluctuation according to the working principle of water meter, we know on water in the water meter is the kinetic energy of flow in table to drive the impeller rotation to drive the meter device to measure.

In the case of no water, connection pipe internal water pressure at the ends of the water meter is balanced, because the & other;
A home a table & throughout;

After modification, the same unit of water meter basic are concentrated in one place installation, and is close.

When adjacent users open valve in an instant, the original pressure balance is damaged, connect the main pipe pressure is lower than before table after the pipe pressure, pressurized water after the table by table before expansion with the decrease of the pressure, there will be a small amount of water flowing through a water meter impeller, form a reversal, the pressure balance.

Water pressure when the valve is closed, sharply before the table tube will rapidly increase, the pressure is greater than the table after before table, table after water will shrink due to compression, at this time and there will be a small amount of water flowing through a meter, forms the forward, reaching a new pressure balance.

Due to the effect of the structure of the water meter, flow meter resistance of different from different directions, though into water is the same, but the speed of the impeller are very different, is faster than the reverse.

But when there is no air in the pipeline, the resulting water quantity is less, generally no more than 1 m3 per month.

In fact, caused by water pressure fluctuation water meter rotation zui fundamental reason is the pipe is air.

We know gas has strong compressibility, when water pressure increases, the air was extrusion flow in a pipe or water appliance of the high, form the compressed gas, when the water pressure and air pressure is equal in balance;

When the water pressure reducing pressure is greater than the water pressure, the compressed gas expansion, promote water flow back, so repeatedly, resulting in a water flow movement, to drive the impeller rotation.

For most of the water meter, the forward count is greater than the reverse, plus the compressibility of the gas is very strong, if the table after the pipe with air and the water pressure fluctuations affect the scale space will be very big, the resulting water amount is larger;

When adjacent water users more frequent, the more the amount of water is less per month also have (
2 ~ 3)
M3, many more than ten cubic meters.

The situation of the trapped air many actually caused the pipeline, such as: tap water in the production and supply will have a lot of gas in the process of integration, at the same time during the construction of a pipeline maintenance, replacement of water meter, the transformation pipeline will also into gas, in addition, stop at occurred off the pipeline network of water area and in the end of the solar water heater and pipes will save gas.

Measures: 1, install the check valve to prevent water pressure fluctuation's influence on the water meter measuring, one-way check valve installed in front of the table can prevent water back.

When pressure after the table before the water pressure is greater than the table, the table after the water has been compressed, water meter forward;

When the table before the water pressure drop, the check valve in the table after the pressure under the action of automatic shutdown, water meter will not produce rotation;

When tables before water pressure rise again, as long as the pressure does not exceed pressure after the check valve, water meter and will not turn again.

Therefore, install a one-way check valve can reduce water meter rotation frequency, can well solve the water pressure fluctuation water meter measuring abnormal problem.

2, the drain tube air due to large pipe air impact on water meter measuring, must therefore be household table of the pipeline of new or modified exhaust.

Exhaust, all equipment shall be of open valve individually, as far as possible will do tube air, reduce the gas content in the water, and for long absence or uninhabited users, should shut down does not stay at the user meter table valve, avoid gas mixed with tube caused by the water, and water meter rotation causes because of pipe network pressure fluctuations.

The gas mass flowmeter is based on the principle that the speed of heat absorption is directly related to the mass flow rate. The sensor of the instrument is composed of two reference level thermal resistances (platinum RTD). One is a mass velocity sensor T1, and the other is a temperature sensor T2 that measures changes in gas temperature. When these two RTDs are placed in the measured gas, one sensor T1 is heated to a constant temperature difference above the gas temperature, and the other sensor T2 is used to sense the measured gas temperature. As the gas mass flow rate increases, the airflow takes away more heat, and the temperature of sensor T1 drops. To maintain a constant temperature difference between T1 and T2, the heating power of T1 must be increased. According to Kim's law of thermal effect. When the moving gas molecules hit the thermal resistor, they absorb and take away heat. The larger the flow rate, the more molecules contacting the thermal resistor, and the more heat absorbed. The heat absorption is related to the number of molecules, thermal characteristics and flow characteristics of a certain gas. So which industries are gas mass flowmeters suitable for? 1.

In this article, we will take an in-depth look at the principles behind Coriolis flow meters and explore their various applications in different industries.

Understanding the Principles of Coriolis Type Flow Meters

Coriolis flow meters work on the principle of the Coriolis effect, which is the apparent deflection of moving objects caused by the rotation of the Earth. In the case of flow meters, the fluid flows through a vibrating tube, causing a slight twisting motion due to the Coriolis force. This twisting motion is measured by sensors and converted into a flow rate. The key advantage of Coriolis flow meters is that they can measure both the mass and volume flow rate of a fluid, making them highly accurate and versatile.

The vibrating tube in a Coriolis flow meter is typically made of metal and is attached to the main pipeline through which the fluid flows. As the fluid moves through the tube, it causes it to twist and vibrate in a specific pattern. The degree of twisting is directly proportional to the mass flow rate of the fluid, allowing for precise measurement. Additionally, the phase shift between the inlet and outlet of the tube can be used to calculate the density of the fluid, further enhancing the accuracy of the measurement.

Advantages of Coriolis Flow Meters
