Turbine Gas Air Steam Flow Meter Transmitter
1.introduction of gas turbine flow sensor / transmitter
This Turbine Gas Air Steam Flow Meter Transmitter does not have a live display function, and only transmits the flow signal of the working condition far away. The instrument is low in price, flexible and convenient, and small in size. It is especially suitable for computer control systems such as secondary display, PLC and DCS.
When the airflow enters the flowmeter, it first passes through the leading fluid 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 magnets on the rotating transmitting disc periodically change the magnetic field of the sensor, thereby inducing a proportional relationship with the volumetric flow of the fluid at both ends of the sensor. Pulse signal.
