Gas turbine measurement principle introduction

Gas turbine measurement principle
When the gas enters the flowmeter, it first passes through the leading structure of the independent movement and accelerates. Under the action of the fluid, since the turbine blade is at an angle to the fluid flow direction, the turbine generates a rotational moment, which starts after the turbine overcomes the resistance torque and the friction torque. Turn. When the moments reach equilibrium, the rotational speed is stable, and the rotational speed of the turbine is linear with the flow rate. The magnet on the rotating transmitting disc periodically changes the magnetic reluctance of the sensor, so that the frequency induced at both ends of the sensor is proportional to the volumetric flow of the fluid. Pulse signal. The signal is amplified by the preamplifier, and the pressure and temperature signals detected by the pressure and temperature sensors are simultaneously sent to the flow totalizer for processing, and the standard volume flow rate and the standard volume total are directly displayed.
