Petroleum Chemical Engineering Steel Waste Water Treatment 4-20mA Electromagnetic Flow Meter
Description
Electromagnetic flowmeter is composed of the sensor and smart converter, and the sensor consists of measuring tube, electrodes, excitation coils, iron core and shell and other components. After the traffic signal is amplified, processed and operated by convertor, you can see the instantaneous flow, cumulative flow, output pulse, analog current and other signals for the measurement and control of fluid flow. It is suitable for the conductive medium whose conductivity is more than 5us/cm, it possesses a variety of power supply and output signal , using the standard RS485 serial communication interface, supports the international standard MODBUS protocol and GPRS and other wireless or wired communication network methods, also has the accumulative pulse equivalent output. It has the measurement, display , remote data transmission, wireless remote control, alarm, remote wireless meter reading system (computer management software and databases) , and other functions.
