Ultrasonic Domestic Gas Meter
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
