The advantages of electromagnetic flowmeter in the measurement of sediment sewage

1. The electromagnetic flowmeter has no mechanical inertia and is sensitive to the reaction. It can measure the instantaneous pulsating flow, and can also measure the flow in both directions.
2. The output of the electromagnetic flowmeter is only proportional to the average flow velocity of the measured medium, and is independent of the flow state (laminar or turbulent flow) under a symmetric distribution. Therefore, the electromagnetic flowmeter has an extremely wide measuring range, and its measuring range can reach 100:1, and some even reach a running flow range of 1000:1.
3. The sensor of the electromagnetic flowmeter has a simple structure, and there are no movable parts in the measuring tube, and there are no throttling parts that hinder the fluid flow. Therefore, when the fluid passes through the flowmeter, it does not cause any additional pressure loss, and is one of the flow meters that operate the energy consumption in the flowmeter.
4. The scope of industrial electromagnetic flowmeters is extremely wide, ranging from a few millimeters to several meters, and the domestic real-flow calibration equipment with a diameter of 3m has laid the foundation for the application and development of electromagnetic flowmeters.
5. The electromagnetic flowmeter is a volume flow measuring instrument. During the measurement process, it is not affected by the temperature, viscosity and density of the measured medium in terms of conductivity (in a certain range). Therefore, the electromagnetic flowmeter can be used to measure the flow rate of other conductive liquids only after being calibrated by water.
6. It can measure the flow rate of smear medium, corrosive medium and suspended liquid-solid two-phase flow. This is due to the fact that there is no obstructive flow component inside the metering tube. Only the measuring tube lining and the electrode are in contact with the fluid to be measured, and the material can be selected according to the nature of the fluid to be measured.
