Electromagnetic flowmeter selection

Electromagnetic flowmeter selection instructions

The correct selection of electromagnetic flowmeters is a prerequisite to ensure good use of electromagnetic flowmeters. What kind of electromagnetic flowmeter to choose should be determined according to the physical and chemical properties of the fluid medium to be measured, so that the diameter, flow range, lining material, electrode material and output current of the electromagnetic flowmeter can all be adapted to the measured fluid. The nature and nature and flow requirements.

Measurable fluid

According to the working principle of the electromagnetic flowmeter, the fluid that can be used to measure the flow of the electromagnetic flowmeter must be conductive. Strictly speaking, except for high-temperature fluids, any fluid with a conductivity greater than 5μ/cm should be selected by the corresponding electromagnetic flowmeter. It measures the flow rate. Therefore, non-conductive gases, steam, oil, acetone and other substances cannot use electromagnetic flowmeters to measure the flow rate.

Determination of sensor caliber

The flow rate of the flowmeter is preferably within the range of 0.5-10m/s. At this time, the diameter of the flowmeter can be selected to be the same as the diameter of the user's pipeline. When the flow velocity is lower than 0.5m/s, it is better to increase the flow velocity locally at the instrument part, and adopt the method of shrinking the tube.

Choice of integral type or separate type

Integral type: In the case of a good site environment, the integrated type is generally used, that is, the sensor and the converter are assembled into one.

Separate type: That is, the sensor and converter are installed in different places separately. Generally, the separate type is selected when the following situations occur.

⑴ The ambient temperature or the radiation temperature on the surface of the flowmeter converter exceeds 60°C.

⑵Occasions where pipeline vibration is large.

(3) Severely corroded the aluminum shell of the converter. To

⑷Occasion with high humidity or corrosive gas on site.

⑸The flowmeter is installed in high-altitude or underground debugging inconvenient occasions. To

When ordering, the separation distance between the sensor and the converter should be indicated, generally not more than 200m, and the converter is wall-mounted.
