Electromagnetic Flowmeter

PMF Series Electromagnetic Flowmeter

It is suitable for the conductive medium whose conductivity is more that 5μs / cm, and it not only has a wide

nominal diameter range, but also adapts to various actual environmental conditions. In addition, it possesses a variety of power supply methods and signal output using the standard RS-485 serial communication interface, as well as supports the international standard MODBUS-RTU protocol and GPRS and other wireless or wired communication network methods, and also has the accumulative pulse equivalent output. It provides the wireless meter reading system that can access the network in a long- distance (computer management software and databases).

Functional characteristics

◆ Excellent measurement repeatability and linearity

◆ Good reliability and anti-interference performance

◆ Good pressure resistance sealing ability

◆ Low pressure loss measurement tube

◆ High intelligentization

◆ Maintenance-free

  Ordering instruction

The following questions should be clear when selects the electromagnetic flow meter :

(1) The medium to be measured must be conductive fluid, and it isn't available to the gas, oil, organic solvents and the non-conductive medium.

(2) When selects the model and specification, we should provide the measurement range of the electromagnetic flowmeter for the manufacturer, then the factory should make a demarcation within the scope of this measure in order to ensure accuracy of the instrument.

(3) The users should provide manufacturers with the medium's process parameters, flow rate and temperature, pressure and other parameters of the selection table, then based on these parameters, select the appropriate meter.

(4) When selects the separate body-type electromagnetic flow meter, the users should propose wiring length requirements to the factory according to the sensor distance away from installation location of converter.

(5) If users need to install accessories, such as supporting flange, metal ring gasket, bolts, nuts, washers and other additional requirements, they can put them forward when ordering.
