Ultrasonic Flare Gas Flowmeter
The Lauris FF1225 series Ultrasonic Flare Gas Flow meter, designed and manufactured for accurate flare gas metering. Lesser meter technologies, not “Fit For Purpose” are at times selected in a cost cutting effort These inferior solutions can result in inaccurate flow measurements and higher maintenance costs.
The FF1225 delivers accurate gas flow measurement over a wide range with minimal maintenance intervention. The flow meters are offered with several options including local or remote mount transmitter, temperature and pressure transducers, and a multi-path version that provides flow uncertainty of better than 1%. Both the local or remote LCD display shows velocity, flow rate, total flow.
