Large diameter electromagnetic flowmeter

Electromagnetic flowmeters that measure flow according to Faraday's law of electromagnetic induction. Electromagnetic flowmeters have the advantage of minimal pressure loss and a large range of measurable flow rates. The ratio of the maximum flow rate to the minimum flow rate is generally more than 20:1. The applicable industrial tube diameter is wide, up to 3 meters. The output signal and the measured flow rate are linear, and the accuracy is high.

1. First make sure that the pipe is full of fluid.

2. If the pipe is too close to the wall, the probe can be installed on the diameter of the pipe with an inclination angle instead of installing it on the diameter of the horizontal pipe. Z method should be used to install the probe

3. Carefully select the dense part of the pipe and polish it thoroughly, apply a sufficient amount of chelating agent to install the probe;

4. The metal pipe with serious fouling on the inner surface of the electromagnetic flowmeter can be used to make the scaling part fall off or crack. However, it should be noted that this method sometimes does not help the ultrasonic waves because of the gap between the scaling and the inner wall. Transmission.

5. Carefully and carefully move each probe near the mounting point to find the maximum signal point to prevent the ultrasonic beam from reflecting the expected area due to fouling on the inner wall of the pipe or due to local deformation of the pipe. Installation point
