Control of electromagnetic flow meter scale grounding and installation requirements

Abstract: the control of electromagnetic flow meter scale grounding and installation requirements of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: the electromagnetic flowmeter installation, pay attention to the sensor must be separate grounding, which requires the grounding ring should be reliable grounding, grounding resistance less than 10, otherwise may cause no order or report to the police. Some people often grounding is not standard, lead to appear in the future. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a control of electromagnetic flow meter scale grounding and installation requirements for details. In the installation of the electromagnetic flowmeter, attention should be paid to the sensor must be separate grounding, which requires the grounding ring should be reliable grounding, grounding resistance less than 10 & Omega; Or you could do a lot, no order or report to the police. After some people often grounding is not standard, lead to some problems cannot be found, the control group, the installation of the electromagnetic flowmeter problem, describes some attention points, for readers' reference. In the installation of the electromagnetic flowmeter, attention should be paid to the sensor must be separate grounding, which requires the grounding ring should be reliable grounding, grounding resistance less than 10 & Omega; Or you could do a lot, no order or report to the police. Pay special attention when installation, can't put the grounding and protection of gasket. Electromagnetic flowmeter separation type grounding in principle should be at the side of the sensor, converter grounding should be in the same place. Such as sensors in a pipeline cathodic corrosion protection, in addition to the sensor and grounding ring together, with a thick copper wire ( 16mm2） Bypass the sensor jumper pipe on two connecting flange, isolation between the cathodic protection current and sensor. Control of electromagnetic flowmeter installation position requirement should be paid attention to in using the environment to avoid external electromagnetic interference, especially to avoid the interference of power frequency electromagnetic field. Some field of high power motor, such as large transformer equipment can produce interference of flowmeter measurement, an error indicator. You also need to note is be sure to use the manufacturer with the instrument (attached Or regulation models) Signal cable, because the converter and the distance between the sensor is subject to the conductivity and the signal measured medium cable type, namely, the distributed capacitance of the cable, wire section and shielding layer, etc. Usually single shielded cable is used for industrial water or acid alkali, can transmit distance of 100 m; And low electrical conductivity of liquid and the transmission distance is longer, according to the rules to use 3 layers shielded cable. To avoid interference signal, the signal cable must be within the earthing protection of the steel pipe, single can't install the signal cable and power supply cord in the same pipe. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

Nowadays, it is very common for us to utilise in electromagnetic flow meter slurry. And the quality of is decisive to production efficiency.

A detailed plan must be developed if we hope to reach your profitability goal. Once we have a certain figure in mind, Beijing Sincerity Automatic Equipment Co., Ltd and our staff need to determine all the steps necessary to reach that goal and act on them.

In terms of mass flow meter, why is it different than other production? How does it fit a true need or desire for your requires? Is it simple to use? Make life easier?
