K-factor (k value) is a coefficient calculated by calibrating and comparing the instrument with other measuring devices that meet the accuracy requirements before it is put into use
this coefficient is a fixed value, which is the actual coefficient obtained by the flowmeter manufacturer after calibrating each instrument, and has nothing to do with the initial design
gear flowmeter, also known as constant displacement flowmeter, referred to as PD flowmeter, is a kind of high accuracy in flow meters, especially suitable for high and low viscosity medium flow measurement. The micro flowmeter uses mechanical measuring elements to continuously divide the fluid into a single known volume part, and measures the total volume of fluid according to the number of times that the metering chamber fills and discharges the fluid of the volume part step by step and repeatedly
extended data:
1) before the flowmeter is installed, the pipeline must be thoroughly cleaned. In the whole pipeline system, if there is no strict filter device, the filter should be installed in front of the instrument to prevent impurities from entering the meter
The flowmeter should be installed at the outlet of the pump, and the flow control valve should be installed at the downstream of the instrument. When in use, first open the upstream stop valve, and then slowly open the downstream flow control valve or stop valve. Do not open or close suddenly When the instrument is in use, it should be full of liquid.
