Burks bklw turbine flowmeter

The fluid flows through the sensor housing. As the blade of the impeller has a certain angle with the flow direction, the impulse force of the fluid makes the blade have a rotating moment. After overcoming the friction moment and the fluid resistance moment, the blade rotates. After the moment is balanced, the rotating speed is stable. Under certain conditions, the rotating speed is proportional to the flow rate. Because the blade The sheet is in the magnetic field of the signal detector (composed of permanent magnetic steel and coil). The rotating blade cuts the magnetic field line and periodically changes the magnetic flux of the coil, so that the electric pulse signal is induced at both ends of the coil. The signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument, Shows the instantaneous and cumulative flow of the fluid. In a certain flow range, the pulse frequency f is directly proportional to the instantaneous flow Q of the fluid flowing through the sensor, and the flow equation is: 0 = 3600xf / K

Where: F -- pulse frequency [HZ]

K -- instrument coefficient of sensor [1 / m3], given by "calibration sheet".

Q -- volume flow of fluid (in working state) [m3 / h]

3600 -- conversion factor

The instrument coefficient of each sensor is calibrated by the company and written in the qualification certificate. When the K value is set in the supporting display instrument, the instantaneous flow and cumulative flow can be displayed.
