Introduction to stainless steel electromagnetic flowmeter

Stainless steel electromagnetic flowmeter,JTLDB stainless steel electromagnetic flowmeter measurement accuracy is not affected by fluid density, viscosity, temperature, pressure and conductivity changes, sensor voltage signal and average velocity is linear, so the measurement accuracy is high.

JTLDB stainless steel electromagnetic flowmeter measurement accuracy is not affected by fluid density, viscosity, temperature, pressure and conductivity changes, sensor voltage signal and average velocity linear relationship, so the measurement accuracy is high.Stainless steel electromagnetic flowmeter measures open flow parts in the pipeline, so there is no additional pressure loss;There are no moving parts in the measuring pipe, so the sensor life is very long.As the induction voltage signal of stainless steel electromagnetic flowmeter is formed in the whole space full of magnetic field, which is the average value of the surface of the pipe, the straight pipe segment required by the sensor is shorter, with the length of 5 times the diameter of the pipe.Stainless steel electromagnetic flowmeter sensor part only lining and electrode contact with the measured liquid, as long as a reasonable choice of electrode and lining material, can resist corrosion and wear.

How to select electromagnetic flowmeter correctly

What kind of electromagnetic flowmeter to choose should be determined according to the physical and chemical properties of the medium being measured.By the principle of electromagnetic flowmeter, electromagnetic flowmeter can choose to measure flow of the fluid must be conductive, strictly speaking, in addition to the high temperature fluid, just any fluid conductivity is greater than 20 us/cm can choose corresponding electromagnetic flowmeter to measure flow rate, because the conductive materials such as gas, steam, oils, acetone cannot select electromagnetic flowmeter to measure flow rate.

Determination of the caliber of the sensor

The flow rate of the flow meter should be within the range of 0.1-5m/s. At this time, the diameter of the flow meter can be selected to be consistent with the diameter of the user's pipe.

Selection of three electrodes and grounding ring materials

Stainless steel electromagnetic flowmeter

When selecting electrode materials, the corrosion resistance of the tested media should be considered, generally one grade higher than that of the process pipeline materials.

The earthing ring can be made of the same material as the electrode or the same material as the process pipeline.

When the process pipeline is a metal pipeline with no insulation coating on the inner wall, the earthing ring may not be selected.
