Product Overview
The MUGF-SB Ultrasonic gas flowmeter is based on the principle of acoustic transit time to calculate the average gas move velocity by measuring upstream and downstream time, in which the ultrasonic waves generated by a pairs of by-directional transducers assembled with an angle respect to axis.
- No moving parts, low pressure drop, long life span;
- Bi-directional measurement;
- Simple installation, easy maintenance;
- High accuracy and good reliability;
- Ex-proof: Exd(ib)IIBT4 (exclude ecetylene);
- Temperature and pressure compensation;
- Suitable for small flowrate and large size pipe.
