Working principle of sanitary electromagnetic flowmeter:

Sanitary electromagnetic flowmeter is an induction meter to measure the volume flow of conductive medium in the tube according to Faraday's electromagnetic induction law. In addition to measuring the flow rate of general conductive liquid, it can also measure the volume flow rate of liquid-solid two-phase flow, liquid flow with high viscosity and saline, strong acid and strong alkali liquid. Widely used in chemical, environmental protection, metallurgy, medicine, paper, water supply and drainage industries.

Product features:

No moving parts in the pipeline, open flow components, almost no additional pressure loss in the measurement.

The measured results are independent of physical parameters such as velocity distribution, fluid pressure, temperature, density and viscosity.

The range can be modified online according to the actual needs of the user.

High definition backlight LCD display, all Chinese menu operation, easy to use, easy to operate, easy to learn and understand.

Using SMD device and surface mount (SMT) technology, the circuit reliability is high.

The 16-bit embedded microprocessor is adopted, the calculation speed is fast and the precision is high, the programmable frequency is low frequency rectangular wave excitation, and the stability of flow measurement is improved.

Full digital volume processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range up to 150:1

Ultra-low EM1 switching power supply, wide range of supply voltage, good EMC resistance.

With RS485, RS232, Hart and Modbus digital communication signal output.

It has the function of self - check and self - judgment, and provides the sensor with the function of infinite nonlinear correction.

Power off protection, the operation result of the flow meter and the parameters set by the user will not disappear after power off, EEPROM can protect the set parameters and cumulative value

Converters and sensors are equipped with a variety of protection registration and installation methods, including IP68 level for submersible installation.
