Electromagnetic flowmeter sensor

Electromagnetic flowmeter sensor, electromagnetic flowmeter sensor is a very popular flowmeter commodity in the flowmeter market at the present stage. Many customers want to know and understand the characteristics and functions of electromagnetic flowmeter sensor.Many people are also not very clear about the electromagnetic flowmeter is how a kind of sensor machinery equipment, today we will give you a detailed introduction of the electromagnetic flowmeter sensor is how a flowmeter commodity.

Electromagnetic flowmeter sensor, unlike people usually touch the flow meter goods.Electromagnetic flowmeter sensor is generally composed of two parts, which are generally composed of electromagnetic flowmeter and electromagnetic induction flow sensor.What is the electromagnetic flowmeter sensor used for? Many people also feel more curious. The key of the electromagnetic flowmeter sensor is to measure the instantaneous flow and volume flow of some fluid and conductive liquid.Just to give you a better idea of what the volume of this liquid is.

Mounting position and flow azimuth electromagnetic induction flow sensors may be installed horizontally, vertically or obliquely.When installing horizontally, the sensor electrical level shaft must be placed horizontally.

That avoids the short-term insulation of the electrical level caused by the bubble brought in by the fluid;The electrical level can also be prevented from being covered by alluvial matter in the fluid.Do not install the sensor at a higher level to prevent vapor accumulation. Install the sensor at a higher level in the piping.

Vertical installation, should be in the direction of the flow upward, so that no flow or flow is very hour, the fluid often brought into the heavy solid particles moved down, and the light fatty substances raised the electrical level of the sensor.When measuring the solid - solid flow, such as slurry, slurry, vertical installation can avoid solid - phase sensing settling and sensor lining unsymmetrical damage.In a down pipe outlet, for poor installation site, should also be avoided.

There should be some back pressure at the sensor installation place. The immediate emptying of the sensor inlet and outlet may lead to non-full liquid in the measurement tube. This is a poor installation place and should be avoided.

In order to prevent the negative pressure in the sensor, the sensor should be installed in the back of the pump, not installed in the front of the pump.

If the sensor is installed on the road with negative electrode etch protection tube, in addition to the sensor and the earthing ring are grounded together, the thick copper wire should also be used to avoid the sensor and grounding on the two flanges of the pipeline, so that the cathode protection current is between the sensor.

Electromagnetic flowmeter shows negative flow during installation or operation. This is considered normal. Install again.The sensor is not installed according to the inflow indicator, resulting in the measurement of the opposite direction.There will certainly be a way to deal with the failure, so this is not a big worry.

The measuring line is empty or not filled with gas.At this point, the flowmeter will display a negative value or the flow value will fluctuate.The power cord of the sensor is connected in reverse, because the electromagnetic flowmeter has the function of positive and negative flow measurement and shows the reverse flow.Switch the power cords.Fill the pipe with the measured medium so that the flowmeter has a measurement standard.
