Sensor design solves wet-gas flow measurement problems
The new optional Wet Gas (WG) MASSter Sensor (photo) delivers accurate, repeatable gas-flow measurement in the presence of moisture and condensation droplets. Available with the Model ST80 Series flowmeters, this new WG sensor configuration features a mechanical design that shunts moisture, condensation and water droplets away from the thermal flow sensor, thus maintaining an accurate gas-flow measurement while minimizing errors that could occur due to a cooling effect on the sensor. The WG MASSter Sensor option can be used in applications that have either moisture entrained in the gas or for protection against down-the-pipe rain in larger, vertical stacks. The ST80 Series flowmeters with the WG MASSter Sensor option are suitable for pipe diameters from 1 to 99 in. (25 to 2,500 mm) and air/gas temperatures up to 850°F (454°C). They have an accuracy of±1% of reading,±0.5% of full scale and repeatability of±0.5% of reading with flowrates up to 1,000 ft3/s (305 Nm3/s) and 100:1 turndown. — Fluid Components International, San Marcos, Calif.
