Product Description

Product introduction:
The ultrasonic gas meter for industry and commerce is a fully electronic gas meter that uses the principle of ultrasonic time difference method for flow measurement. The meter has the characteristics of accurate measurement, wide range ratio, wide temperature adaptation range, strong temperament adaptability, small size, high reliability, and high temperature and pressure compensation function. The product adopts the ultrasonic scheme of full independent research and development, breaking the monopoly of foreign technology and realizing the independent control of key technologies.

Product features:
• Accurate measurement: full flow point electronic calibration, high-precision correction
• Sensitive metering: small flow sensitive metering
Small size: small size, easy site selection, installation and maintenance
Temperature and pressure compensation: real-time temperature and pressure compensation, reduce gas loss, reduce supply and marketing difference
Safety gas monitoring: it has a variety of gas safety warnings such as abnormal large flow gas consumption, slight leakage, continuous constant flow gas consumption, and no gas for many days.
• High reliability: fully electronic metering, no moving parts
• Public network communication, decentralized deployment

Technical advantages:
• Independent research and development of ultrasonic flow channel
• Independent research and development of transducer
• Autonomous algorithm of domestic metering chip
• Independent research and development of flow verification equipment, sealing testing equipment, automatic production line
