The EMCO wet gas meter is used to measure the flow rate in natural gasses with a certain level of liquid present. Based on the classical venturi tube according to ISO 5167-4 with single pressure tappings. A third tapping may be applied for liquid flow rate determination using the pressure loss ratio method. The system consists of a classical venturi tube in a metering section. The wet gas meter is designed to perform reliable measurements in applications such as well testing, hydrocarbon metering and monitoring of critical factors such as water breakthrough. The system consists of a classical venturi tube in a metering section. Differential pressure transmitter(s), static pressure transmitter or multivariable transmitters, a thermowell and a temperature transmitter an instrument cabinet, a wet gas flow computer and an over reading correction algorithm and if required for liquid flow determination tracer dilution system.
