Ultrasonic Gas Flow Meter FA1221
Upstream 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.
Features
- Low measurable velocity (from 1 cm/s)
- High turn down ratio (2000:1)
- Uncertainty less than +/-2% from reading
- Repeatability better than 0.5%
