Second, the principle of natural gas turbine flow meter
When the fluid flows into the flowmeter, it is rectified and accelerated under the action of an inlet-integrated rectifier. Since the turbine blades are at a certain angle with the fluid flow direction, the turbine generates a rotational torque. After the friction torque and the fluid resistance torque are overcome, the turbine Start rotating. In a given flow range, the angular velocity of the turbine rotation is proportional to the volume flow of the fluid. According to the principle of electromagnetic induction, a magnetic sensor is used to induce a pulse signal proportional to the volumetric flow of the fluid from a coaxially rotating signal wheel. The signal is amplified, filtered and shaped to enter the intelligent flow integration together with the temperature and pressure sensor signals. instrument micro processing unit performs arithmetic processing, and the total gas volume flow and directly displayed on the LCD <br> <br> three, gas turbine flowmeter features
