Product Overview

Introduction:
The ultrasonic series smart gas meter was developed on the basis of ultrasonic measurement technology. It features a compact design without moving components and possesses advantages such as high reliability, high precision, and a wide measurement range ratio. These combined advantages make it a highly sophisticated and reliable solution for modem gas metering applications.

Approvals:

Main Advantages

Compact and Lightweight

Characterized by a smaller size and lighter weight compared to diaphragm gas meters under the same flow rate

High Precision and Wide Range Ratio

Electronic Volume Conversion

The built-in temperature and pressure sensors facilitate real-time volume conversion to the base condition

Protection against Interference and Tampering

Benefiting from ultrasonic measurement technology, it is immune to magnetic interference. Additionally, it is equipped with tamper detection and timely reporting features

Multiple Gas Safety Detection

It includes functions such as overflow detection, reverse flow detection, continuous flow detection, over-high/over-low temperature/pressure alarm, dismantling detection, and water ingress detection

Firmware Update

Supports both OTA and local firmware updates, which enhance maintenance efficiency and reduce operational costs

Operating Principle:

The ultrasonic gas meter calculates the gas flow rate V by measuring the time difference between Tup (the time the upstream transducer sends an ultrasonic wave to the downstream transducer) and Tdown (the time the downstream transducer sends an ultrasonic wave to the upstream transducer), which in combination with the cross-sectional area of the flow channel S calculates the gas flow rate.
