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
