Product details

Product Instructions

Working principle of electromagnetic flowmeter measurement principle 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 E. Electromotive force e is proportional to the magnetic flux density B, measure the inside diameter d and the product of the mean velocity v. Electromotive force e (traffic signal) checked out by electrodes and cables to the converter. Converter after the traffic signal will be amplified, to display fluid flow and energy output pulse, analog current signals for flow control and the flow adjustment.

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

4. Magnetic flow meter use SMD devices and SMT technology.

5. Self-checking function.
