Description
The gas turbine flowmeter absorbs the leading technology of foreign flow meters and is optimized and designed. It is independently developed by integrating gas mechanics, fluid mechanics, electromagnetics and other theories. It is a new type of temperature, pressure, flow sensor and intelligent flow totalizer. A generation of high-precision and high-reliability gas precision metering instruments with good low-pressure and high-pressure metering performance, multiple signal output modes and low sensitivity to fluid disturbance. It is widely used in the measurement of natural gas, coal-to-gas, liquefied gas and other gases. Measurement.
principle
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 blades are at a certain angle with the flow direction of the fluid, the turbine generates a rotational torque, which starts after the turbine overcomes the resistance torque and frictional torque. Turn. When the torques reach balance, the rotational speed is stable, and the turbine rotation speed has a linear relationship with the flow rate. The magnet on the rotating sending disk periodically changes the sensor reluctance, thereby sensing a pulse at both ends of the sensor that is proportional to the fluid volume flow rate. Pulse signal. After the signal is amplified and shaped by the preamplifier, the pressure and temperature signals detected by the pressure and temperature sensor are simultaneously sent to the flow totalizer for processing, and the standard volume flow rate and standard volume total amount are directly displayed.
