Electromagnetic Flow Meter for Conductive Liquid

Working Principle

Working principle of electromagnetic flow meter measurement is based on the Faraday law of electromagnetic induction. Measurements of the flow meter tube is lined with insulating material of a non-magnetic alloy spool. Two clicks along the diameter through-wall fixing on the measuring tube. The electrode head is flush with the lining inner surface. Field coil by waves when pulsed excitation by both parties, will be measured perpendicular

to the pipe axis direction produces a magnetic flux density of the magnetic field b. At this point, if you have

some electrical conductivity of fluid flows through the measuring tube, cut magnetic lines of induction electromotive force. 

Features:

1.No moving and blocked flow parts in the pipeline, almost no additional pressure loss in the measurement.

2.Measurements results are independent of physical parameters, such as flow distribution, fluid pressure, temperature, density and viscosity.

3.On-site modification of the measuring range available.

4.LCD display, easy to use and simple to operate.

5.Using SMD devices and SMT technology.

6.Using 16-bit embedded processors with fast speed and high accuracy, enhancing the stability of measurement.

7.Anti-interference, reliability, measurement range up to 150:1.

8.Ultra low EMI switch, wide range of power supply voltage.

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

10.Self-checking function.

Application:

Due to its unique advantages, it is widely used in the fields of petroleum, chemical industry, steel, light industry, sewage processing, environmental protection, water conservancy project and pharmacy to measure the volume flow of the conducted liquid mediums, such as alkali, salt solution and so on.
