Non-filled tube electromagnetic flowmeter

 Non-filled tube Electromagnetic Flowmeter is a kind of automatic flowmeter that uses the velocity - area method to continuously measure fluid flow in the open pipeline.

It can continuously measure the instantaneous flow rate, velocity, cumulative flow rate and other data in the open non-full pipe.

Especially suitable for sites that need to be measured under the condition of incomplete pipes,such as municipal rainwater discharge pipes, waste water, sewage and irrigation water pipes.

Non-full pipe electromagnetic flowmeter is a small measuring system composed of an electromagnetic velocity sensor, an ultrasonic level gauge and a flow converter, which can continuously measure the flow rate and liquid level of the fluid in the open non-full pipe. As long as the user enters the inner diameter of the circular pipe or the width of the square pipe, the electromagnetic flowmeter of the incomplete pipe will automatically calculate the flow in the pipe. And automatically displays instantaneous flow, flow rate, cumulative flow and other measurement parameters.

Functions and Features:

 It can be used to measure the flow of open non-full pipes (round pipes, rectangular pipes or other special shaped pipes).

It can be used for continuous measurement of municipal rainwater, waste water, sewage discharge and irrigation water pipes.

Can realize automatic measurement of forward and two-way flow;

The sensor can work reliably for a long time under harsh site conditions and sewage quality.

Wide velocity measurements range from 0.01m/s to 15m/s;

High flow measurement accuracy , not affected by downstream back-water, blocking and other factors;

Large screen, backlight LCD display, measurement data can be clearly read under strong light or at night;

Complete function in display and output, it’s able to display the instantaneous flow, flow rate, cumulative flow, liquid level and other measurement data of the liquid in the pipe;

Computer communication interface 232, 485 (optional);

GPRS wireless remote data transmission function (optional);

Timekeeping, counting and timer function when power is off .
