Description
Ultrasonic gas meter is a fully electronic speed metering device developed and produced by our company that uses ultrasonic measurement. It is characterized by non-contact, no moving parts, large range ratio, good linearity, high reliability and high measurement accuracy.
Key Strengths
Low pressure absorption No mechanical wear Good repeatability Ultra compact No moving parts High measuring precision with more stationary error curve Temperature and pressure compensation Stable operation and long service life without noise Non-magnetic element and measurement not easily affected by magnetic field
Key Technologies
Large range ratio Small starting flowrate Two-way measurement Fault self-detection Valve shut-off due to overflow
