Description
MTSB Ultrasonic Gas Flow Meter is based on the theory of acoustic transit time to calculate the average velocity of gas movement by measure time of the upstream and downstream, in which the ultrasonic waves generated by two bi-directional transducers travel along the path angled with respect to pipe axis.
Features
No moving parts, low pressure drop, low maintenance
Bi-directional measurement
Simple installation, excellent performance
High accuracy and good reliablility
Ex-proof: Exd(ib) BT4(exclude acetylene)
Temperature and pressure compensation
Real time LCD display
Self-diagnose
High accuracy up to 0.5%
Application
MTSB Ultrasonic Gas Flow Meter can be applied extensively to the supply, transmission, distribution of most dry gas in fields such as underground air storage, power stations, petrochemical industry, aluminum melters etc. There is a wide range of gas can be measured by MTSB including natural gas, compact gas, compressed air, fuel gas, corrosive gas, poisonous gas, high-purity gas etc.

Notes:
1) The above flow range is in working condition, while flow range standard condition (0.1MPa, 20℃）shall be converted to flow range in working condition for model selection.
2) Unit for pressure is MPa, and unit for temperature is ℃;
3) For MTSB≥4.0MPa, the flow meter must work with pressure ≥0.5MPa
