Characteristics of sewage electromagnetic flowmeter
An electromagnetic flowmeter is an instrument that can be used to measure the volume flow of various conductive liquids in pipes and channels. Its characteristics are as follows:
It adopts a 16-bit embedded microprocessor, featuring fast computing speed, high precision, and programmable low-frequency rectangular wave excitation, which enhances the stability of flow measurement and has low power consumption.
2. It adopts SMD devices and surface mount technology (SMT), ensuring high circuit reliability.
3. There are no moving or flow-blocking parts inside the pipe, and there is almost no additional pressure loss during measurement.
4. On-site, the measurement range can be modified online according to the actual needs of the user.
5. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.
6. There are no flow-blocking components inside the measuring tube, no pressure loss, and low requirements for straight pipe sections. It has good adaptability to slurry measurement.
7. Select electrode and lining materials reasonably, that is, they should have good corrosion resistance and wear resistance.
8. Fully digital quantity, strong anti-interference ability, reliable measurement, high precision, and the flow measurement range can reach 150:1
9. Ultra-low EMI switching power supply, with a wide range of applicable power supply voltage variations and excellent anti-EMI performance.
The measurement results are independent of the flow velocity distribution, fluid pressure, temperature, density, viscosity and other physical parameters.
11. High-definition backlit LCD display, full Chinese menu operation, convenient to use, simple to operate, easy to learn and understand.
12. Infrared handheld operator, 115KHZ communication rate, long-distance non-contact operation of all functions of the converter (optional)
There are three accumulators inside that can respectively display the forward cumulative quantity, reverse cumulative quantity and difference cumulative quantity. It is equipped with a power-off clock inside that can record 16 power-off times (optional).
14. It has digital communication signal outputs such as RS485, RS232, Hart and Modbus Profibus-DP (optional).
15. It has self-checking and self-diagnosis functions.
16. Hourly total volume recording function, recording the total flow volume by hour, suitable for time-of-use metering system (optional)
