Working Principle of turbine gas meter
The turbine gas meter operates by measuring the velocity of the gas flow. The gas enters the meter and passes through a turbine rotor, causing it to spin.
Turbine Rotation and Signal Generation:
The speed of the turbine rotor is directly proportional to the flow rate of the gas. This rotational speed is converted into an electronic signal, which represents the volumetric flow rate.
Electronic Volume Corrector (EVC):
The EVC enhances the accuracy of the measurement by compensating for variations in temperature and pressure. Sensors integrated with the EVC monitor real-time gas temperature and pressure conditions. The EVC applies correction algorithms to calculate the normalized or corrected gas volume, typically referenced to standard temperature and pressure.
Output Integration:
The meter provides an analog output signal (4-20mA), enabling seamless integration with control systems, SCADA, or other data acquisition platforms.
Reliable Performance Under Fluctuating Conditions:
The turbine gas meter combined with the EVC ensures precise and consistent gas flow measurement, even when operating conditions vary significantly.
This combination of turbine technology and electronic correction makes the turbine gas meter with EVC ideal for applications requiring high accuracy, reliability, and adaptability in gas flow measurement.
