Electromagnetic flowmeter features and selection
Electromagnetic Flowmeter is based on Faraday's law of electromagnetic induction for flow measurement flowmeter, the choice of Electromagnetic Flowmeter is the premise that the medium must be electrically conductive, followed by the selection of the following points:
1、According to the size of the common flow rate to decide how large the caliber;
2、According to the medium and temperature selection of the appropriate receiving material, such as electrode material and lining material, mainly corrosion resistance, abrasion resistance degree.
3、According to the pressure to choose the appropriate pressure level flange.
4、According to the power supply is 220VAC or 24VDC and signal output and so on.
5、According to the installation conditions, in order to determine the explosion-proof, protection level, the installation form of split and integrated.
6、In addition to the site environment, select the appropriate shell material, there is no corrosive and so on.
7、The accuracy of the measurement requirements, the reliability of the measurement method, that is, the device will not occur in the operation of the mechanical strength or electrical circuit failure and cause accidents. Measuring instruments, whether in normal production or fault conditions shall not affect the safety of the production system.
8、In order to ensure the safe operation of the instrument on the basis of seeking to improve the accuracy of the instrument and energy saving. To this end, not only to choose to meet the accuracy requirements of the display instrument, but also to choose a reasonable measurement method according to the characteristics of the measured medium.
Electromagnetic Flowmeter has the following characteristics, should also be noted in the selection process:
1、Electromagnetic Flowmeter can be widely used to measure a variety of industrial conductive liquid or slurry. Particularly suitable for a variety of strong acids, alkalis and salts corrosive liquid media, measurement of continuous flow or pulsating flow of these media, can be used to measure a variety of dirty, suspended particles of liquid or large pipe diameter flow. Electromagnetic Flowmeter of these unique uses are some other flowmeter does not have.
2、Electromagnetic Flowmeter transmitter diameter and the measured fluid pipe diameter is identical, no resistance elements, will not cause pressure loss on the fluid, this advantage is also resistance measuring element of the flow meter does not have.
3、Electromagnetic flow transmitter output signal and the measured fluid volume flow is linear This feature with the same Vortex flowmeter, range change is easy, large measurement range, electromagnetic flow transmitter caliber from 15mm to 2.6m, flow rate from 0.3m/s to 10m/s.
4、Electromagnetic Flowmeter to measure the measured liquid volume flow under the working condition, the measurement principle does not involve the influence of fluid temperature, pressure, density and viscosity.
5、Electromagnetic Flowmeter responds quickly and can measure pulsating flow.
