Gas Turbine Flowmeter

Débitmètre pour turbine à gaz

  • The temperature and pressure compensated gas turbine flowmeter integrates a gas turbine flow sensor and a flow integrator. Its main performance indicators have reached the international advanced level. It is an ideal instrument for gas metering in petroleum, chemical, electric power, metallurgical industry, civil boilers, urban natural gas, gas pressure regulating station metering and gas trade metering.

Détail

Working Principle

When the airflow enters the flowmeter, it first passes through a rectifier with a special structure and accelerates. Under the action of the fluid, the turbine overcomes the resistance torque and friction torque and starts to rotate. When the torque reaches equilibrium, the speed is stable, the speed of the turbine is proportional to the gas flow, and the magnetic field is periodically changed by the magnet on the rotating signal disk, so that the pulse generator outputs a pulse signal with a frequency proportional to the flow rate. The microprocessor in the converter counts and calculates the pulse signal to obtain the working flow, and at the same time detects the temperature and pressure of the medium, converts the working volume flow into the standard volume flow according to the volume correction model and accumulates it to obtain the standard volume total.
