applications frequently require gas flow measurements which
presents challenges for conventional instrumentation: clogging
by liquids, no pressure drop, low flow, etc. The FA1221
gas flow meter was developed to solve these problems.
The proprietary ultrasonic axial time-of-flight measurement
provides accurate flow data startting from flow velocities
as low as 1 cm/s. Such high sensitivity enables reliable
measurement of tiny breathing of tanks (gas venting) as
well as the registration of miniscule motion of flare gases,
casing gases and bio gases.
- Low measurable velocity (from 1 cm/s)
- High turn down ratio (2000:1)
- Uncertainty less than +/-2% from reading
- Repeatability better than 0.5%
