What are the advantages of Supmea Instruments electromagnetic flowmeters?
2024-07-05
Electromagnetic flowmeter is mainly used for measuring conductive liquid media, can not be used to measure gas, vapor and a large number of gases containing liquid. Affected by the flow rate distribution, in the axisymmetric distribution of conditions, the flow signal is proportional to the average flow rate. Therefore, before and after the electromagnetic flowmeter must also have a certain length of the front and rear straight pipe section. Susceptible to external electromagnetic interference.
Case introduction
The effect in use is affected by many factors. The truth, reliability and accuracy of the measurement are not only related to the converter, but also depend on the sensor, and the excitation technology of the sensor has a great influence on the flow detection.The advantages of Supmea electromagnetic flowmeter are as follows:
- (1)Simple structure, no moving parts and impede the flow of the measured medium of the disturbing parts or throttle parts, easy to adhere to the solid-liquid two-phase medium is not easy to pipe clogging, wear and tear and other issues. Can make up for the mass flow meter is not easy to measure the shortcomings of such media.
- (2)Electromagnetic flowmeter is a measurement of volume flow meter, its measurement is not affected by the density of the fluid, temperature, pressure, viscosity, Reynolds number, as well as in a certain range of conductivity changes. Electromagnetic flowmeter only need to use water as a test medium for calibration, without additional corrections can be used to measure other conductive liquids. This is the other flowmeter does not have the advantage.
- (3)Electromagnetic flowmeter measuring range is very large, some products measuring range up to 1000: 1. For the same caliber sensor, its full scale as long as the medium flow rate in the range of 0.3 ~ 15m / s can be set arbitrarily. Electromagnetic flowmeter measurement range can cover the turbulent flow and laminar flow state of the two velocity distribution state, which is the differential pressure flowmeter, turbine, vortex and other flowmeter can not be compared with it.
- (4)Measurement principle is linear, high measurement accuracy, and completely electrical signal output, the measurement of the reflection speed, can measure pulsating flow and rapid cumulative total.
- (5)Good corrosion resistance.
- (6)The principle is to measure the average flow rate across the water section, which requires less flow distribution. Therefore, the straight pipe section before and after the sensor is required to be shorter than other flow meters.
- (7)It can measure the flow fluid in both positive and negative directions.
The above is Supmea electromagnetic flowmeter manufacturers to provide you with Supmea electromagnetic flowmeter what are the advantages, you can do some reference according to these contents above, I hope to help users in the use of the process to understand more about the maintenance of the way to reduce the instrument in the use of the process of measurement error, often on the instrument for maintenance and maintenance can effectively improve the performance of the instrument.
