Natural gas turbine flowmeter product features

When the fluid flows into the flow meter, it is rectified and decelerated under the influence of the integrated rectifier dedicated to the air inlet. Since the turbine blades are at a certain angle to the fluid flow direction, the turbine generates a ignition torque at this time. After suppressing the friction torque and the fluid resistance torque, the turbine begins to rotate. Within a certain flow range, the angular velocity of the turbine rotation is proportional to the volume flow rate of the fluid. According to the principle of electromagnetic induction, the monopolizing magnetic sensitive sensor senses a pulse signal proportional to the volume flow rate of the fluid from the coaxial rotating signal wheel. After amplification, filtering, and shaping, the signal enters the microprocessor unit of the intelligent flow integrator together with the temperature and pressure sensor signals for calculation and processing, and the volume flow rate and total amount of the gas are directly displayed on the LCD screen.
