Why should the electromagnetic flow meter be grounded?
Can the electromagnetic flow meter measure pure water?
Let's see below detailed description for the electromagnetic flow meters model selection.
The Electromagnetic Flow meter can be horizontal, Vertical or slide mounted.

China magnetic flow meter selection and get the electromagnetic flow meter price.
Actually, the electromagnetic flow meter consists of two parts, transmitter and sensor.
(3) The measuring range is large, and the diameter of the electromagnetic flow transmitter is from 2.5mm to 2.6m.
In order to make the electromagnetic flow meter operate stable and reliable, the following requirements should be paid attention to when selecting the installation site.
When there is no flow or small flow, the heavy solids in the fluids are down andthe fatty substances are up to be away from the electromagnetic flow meter electrodes area.
To avoid negative pressure(damaging the liners), the electromagnetic flow meter shouldn't mount in the inlet of the pump, outlet is recommended.
(2) The electromagnetic flow meter determines the volume flow rate in the working state by measuring the speed of the conductive liquid.
If the electromagnetic flow meter converter does not consider the fluid density, it is not appropriate to give only the volume flow at normal temperature.
In this regard, we need to pay attention to the use of the above medium with a higher temperature sterilization process,which is with the electromagnetic flow meter lined with a certain risk, if the operation is a little careless, easy to damage the instrument.
If the inner lining material of the electromagnetic flow meter sensor is PTFE, a ground ring should be used to protect the flanged of PTFE from damage.
As long as it is grounded according to the requirements, the mag flow sensor is connected to the metal pipe, and the medium in the metal pipehas a good electrical connection with the earth, so that the electromagnetic flow sensor can no longer be equipped with ground wire.
Hart Communicator and Hart modem can set the electromagnetic flow meter parameters,the communication address is non-zero value, and baud rate is 4800.
When the magnetic flow meter sensor is installed on the plastic pipe or the pipe with insulating paint or paint, the two ends of the mag flow sensor should be installed with ground wire, so that the measured medium in the pipe and the earth short circuit have zero potential,otherwise the electromagnetic flow transmitters cannot work normally.
(3) The installation and commissioning of the electromagnetic flow meter is more complicated than other flow meters, and the requirements are more stringent.
(4) The electromagnetic flow meter measures the volume flow rate of the fluid under test, and the influence of temperature, pressure, density and viscosity of the fluid is not involved in the measurement principle.
When a certain section of the upstream and downstream tubes of the electromagnetic flow tube is not filled with liquid and the pipeline pressure fluctuates,the average flow rate is zero, and the axial flow velocity flowing through the electrode has a certain swing.
(4) When the electromagnetic flow meter is used to measure the viscous liquid with dirt,the sticky substance or sediment adheres to the inner wall or the electrode of the measuring tube, so that the output potential of the transmitter changes, which brings measurement error, and the dirt on the electrode reaches a certain level.
When mounting the electromagnetic flow sensor in Cathodic Protecion Pipe, grounding wires should by pass the sensor and bridge joint the two flanges and isolate the cathodic protection current and mag flow sensor.
The Electromagnetic water Flow meter can be horizontal, Vertical or slide mounted.
Electromagnetic flow meter.
(1) The application of electromagnetic flow meter has certain limitations.
