LZD350/150G series mining electromagnetic flowmeter coal slurry electromagnetic flowmeter

Description :

　　Electromagnetic flowmeter, electromagnetic flowmeter manufacturer, electromagnetic flowmeter supplier, electromagnetic flowmeter manufacturer, coal slurry flowmeter, heavy turbidity fluid flowmeter

　　There are generally two types of flow meters used in coal mines: split type flow meters and integrated flow meters

　　Electromagnetic flowmeter and ultrasonic flowmeter

　　Complete specifications, simple structure, high precision, and accurate measurement; The coefficients before leaving the factory have been calibrated using standard metrology. The gas drainage flow rate in coal mines is measured by the radial pressure measurement method. When the continuous flow fluid passes through the throttling device in the pipeline, the flow velocity of the orifice flowmeter will increase. There is a static pressure difference between the upstream and downstream sides of the throttling device of the orifice flowmeter, and there is a constant relationship between the flow rate and the pressure difference. Therefore, the flow rate of the fluid can be calculated by measuring the pressure difference. LZD350/150G series mining orifice flowmeter

　　Range confirmation

　　The flow rate of the medium measured by the electromagnetic flowmeter for general industrial use should be 2-4m/s. In special cases, the flow rate should not be less than 0.2m/s and should not be greater than 8m/s. If the medium contains solid particles, the commonly used flow velocity should be less than 3m/s to prevent excessive friction between the lining and electricity; For viscous fluids, the flow velocity can be chosen to be greater than 2m/s. A higher flow velocity helps to automatically eliminate the effect of viscous substances attached to electricity, which is beneficial for improving measurement accuracy.

　　Under the condition that the range Q has been determined, the size of the flowmeter diameter D can be determined based on the range of flow velocity V mentioned above, and its value can be calculated by the following formula:

　　Q=πD2V/4

　　Q: Flow rate (㎡/h) D: Inner diameter of pipeline V: Flow rate (m/h)

　　The range Q of the electromagnetic flowmeter should be greater than the expected flow value, while the normal flow value should be slightly greater than 50% of the flowmeter's full-scale scale.
