Single-Ended Ultrasonic Gas Flow Meter

Product Overview

The Single-Ended Ultrasonic Gas Flow Meter is a high-precision instrument designed for gas flow measurement in complex industrial and municipal environments. Utilizing non-contact ultrasonic measurement technology, it provides stable, real-time monitoring under high temperature, high humidity, dusty, and multi-component gas conditions. The device addresses common measurement challenges such as low flow rates, uneven distribution, and unstable flow fields. Its single-ended open-hole installation minimizes maintenance requirements and allows for independent operation or integration with CEMS (Continuous Emission Monitoring Systems). The meter is widely used in municipal, industrial, and energy sectors for accurate gas flow monitoring.

Working Principle

The meter operates on the ultrasonic principle, using line-averaged flow measurement to achieve high-precision, non-intrusive monitoring. Autocorrelation detection technology effectively suppresses ambient noise interference, ensuring accurate measurement across low flow rates (as low as 0.1 m/s) and high flow conditions. The system can simultaneously measure gas temperature and pressure, providing comprehensive flow data, and supports embedded data processing, calibration, configuration, and diagnostics.
