Kurz 454FTB-WGF Wet Gas Flowmeter

The Kurz 454FTB-WGF Wet Gas Flowmeter is a single point insertion thermal mass flowmeter designed for wet gas flow measurement. Kurz 454FTB-WGF thermal mass flowmeter is the only thermal mass flowmeter designed to accurately and reliably measure wet gas flow.


In condensing gas environments such as landfill or digester gas measurement, moisture can cause problems with thermal mass flowmeters. Water droplets forming on the sensors heated element result in an increase in energy to the element.  This causes the meter to report much higher flowrates than are actually occurring. Large water droplets can cause significant flow spikes for up to 30 minutes.


Kurz have adapted their successful 454FTB design by heating the heated sensor to 300°C above the ambient temperature sensor. As the water droplets impact the heated sensor they immediately vaporize and create a layer, caused by the Leidenfrost effect, which diverts the remaining water around the sensor leaving it unaffected by the moisture in the gas.  Access the latest configuration software and more at
