Electromagnetic sewage flowmeter

Overview of Electromagnetic sewage flowmeter
Electromagnetic sewage flowmeter is composed of sewage electromagnetic flowmeter sensor and sewage electromagnetic flowmeter converter. It is used to measure the volume flow of all kinds of conductive liquid in the pipeline and channel.
Electromagnetic sewage flowmeter can be widely used in municipal water supply, iron and steel, petroleum, chemical, electric power, industry, water conservancy, water resources and other departments of the volume flow measurement of conductive liquid, especially suitable for channel, small river flow measurement and environmental treatment of sewage measurement.

Main features of Electromagnetic sewage flowmeter
Electromagnetic sewage flowmeter is simple structure, firm and reliable, long service life
The measuring tube has no moving parts and components resistance, no pressure loss, won't produce congestion measurement, reliable and strong anti-jamming capability Small volume, light weight, easy installation, less maintenance, wide range measurement is not affected by the fluid temperature, density, pressure, viscosity, conductivity, etc Can install on servant road opening reformation, construction installation is simple, Small engineering than the general electromagnetic flowmeter cost and installation cost is low, especially suitable for large and medium caliber pipeline flow measurement using advanced processing technology, solid state packaging, long life, so that the instrument has good measurement accuracy and stability

Installation requirements of Electromagnetic sewage flowmeter
1) Selection of installation environment for sewage electromagnetic flowmeter:
Keep away from devices with strong electromagnetic fields, such as large motors, large transformers, and large frequency converters.
The installation site should not have strong vibration, the pipeline is fixed firmly, and the ambient temperature does not change much.
The installation environment should be convenient for installation and maintenance.
2) Selection of installation position of sewage electromagnetic flowmeter:
The installation position must ensure that the pipe is always filled with the liquid to be tested. Select the liquid flow pulse small place, that is, should be far away from the pump and valve, elbow and other local resistance parts. When measuring two-phase (solid, liquid and gas, liquid) liquids, the place which is not likely to cause phase separation should be selected. The inner diameter or circumference of the measured pipe should be easy to measure and the ellipticity should be small.
3) Length of straight pipe section of sewage electromagnetic flowmeter: the length of straight pipe section on the upstream side of the sensor installation pipeline should be greater than or equal to 10D, and the length of straight pipe section on the downstream side should be no less than 5D(D is the diameter of the measured pipeline).
4) Flow control valve and regulating valve:
The flow control valve shall be installed in the pipeline under test on the upstream side of the sensor, and the flow regulating valve shall be installed on the downstream side of the sensor.

Technical features of Electromagnetic sewage flowmeter
The measurement accuracy is not affected by the fluid density, viscosity, temperature, pressure and conductivity changes, the sensor induced voltage signal and the average flow rate is linear, so the measurement accuracy is high.
Measure open flow in the pipe, so there is no additional pressure loss; The sensor has a long life because there are no moving parts in the pipeline.
Because the induced voltage signal is formed in the entire field-filled space and is the average of the load surface of the pipe, the straight pipe section required for the sensor is shorter, with a length of 5 times the pipe diameter.
Only the lining and electrode of the sensor part are in contact with the liquid under test. As long as the electrodes and lining materials are reasonably selected, they can be resistant to corrosion and wear.
The converter adopts the international latest and most advanced MCU and surface mount technology (SMT), reliable performance, high precision, low power consumption, stable zero point, convenient parameter setting. Click Chinese LCD to display cumulative flow, instantaneous flow, flow rate, flow percentage, etc.
Two-way measurement system, can measure forward flow, reverse flow. Special production technology and high quality materials are adopted to ensure that the performance of products remains stable for a long time.
