Gas Turbine Flowmeter

When the air flow enters the flowmeter, it first passes through the leading structure of the independent core and accelerates. Under the effect of the fluid, the turbine blade is at a certain angle with the flow direction of the fluid. At this time, the turbine generates a rotational torque. After the turbine overcomes the resistance torque and friction torque, it starts to rotate. When the torque reaches balance, the belt is stable, and the rotational speed of the turbine is linear with the flow, The magnetic resistance of the flow sensor is periodically changed by the magnet on the rotating signaling disk, so that the flow sensor can sense a frequency signal proportional to the volume flow of the fluid. The signal is amplified by the preamplifier, shaped, and then transmitted to the microprocessor of the flow totalizer for operation with the pressure and temperature signals detected by the pressure and temperature sensors, which can be converted to display the standard volume flow and the standard volume cumulative total.
