What is the working principle of a liquid turbine flowmeter?
The liquid turbine flowmeter is the speedy kind of flowmeter dependent on the principle of balancing the torque. The harmonious flow passes through the housing of the sensor because the blades of the impeller have a particular angle along the direction of the flow. The pressure of the fluid forces the edge to make the rotational torque. The blades start rotating when the resistance of the fluid and friction torque have overcome. The torque is stable when the torque gets the balance. Under some specific conditions, speed is directly proportional to the flow rate. Because of the blade’s magnetic permeability, there is a magnetic field of the signal detect consisting of coils and permanent magnets.
The blade that is rotating cuts down the magnetic lines of the forces. The magnetic flux of the coil keeps changing periodically. The signals of electrical pulse get induce at both ends of the coil. This signal gets amplify and shaped again by the amplifier. Continuously, there is a formation of the rectangular shape pulse wave and a particular amplitude. Its transmission is displayed on the liquid turbine flowmeter remotely. The display is of the total amount of the fluid or instant flow. In some specific flowing ranges, the frequency of the pulse f is directly proportional to the instantaneous flow Q of the flowing fluid through the sensor.
The equation of the flow: Q=3600*f/k
fà frequency of the pulse in Hz

QÃ is the instantaneous flow (under specific working conditions) [m3/h]

The meter coefficient of every sensor is fill in the verifying certificate by the manufacturer of the liquid turbine flowmeter. The value of k is present to match the displaying instrument. The display is of the instantaneous flow and total flow.
