Cross-Stack Ultrasonic Flue Gas Flowmeter Gasboard-7900M

Introduction

Gasboard-7900M is a high-temperature ultrasonic flowmeter independently developed by Cubic Instruments. Based on the TOF (Time of Flight) principle of ultrasonic waves, one or more pairs of ultrasonic transmitting and receiving devices are installed in the upstream and downstream directions of the medium respectively. The gas flow rate in the flue is calculated through the time difference of ultrasonic wave transmission, and the volume flow rate of the flue gas is calculated according to the cross-sectional area of the flue duct.

This flowmeter adopts the non-contact measurement method, which can effectively solve the measurement difficulties such as unstable flow fields and uneven flow velocity distribution in the pipeline. It can maintain continuous real-time stable monitoring in the harsh environment of high temperature, high humidity and high dust during the flue gas discharge process.

Features

High Precision: Line-average flow velocity measurement with accuracy ≤±1.5% F.S., measuring flow rates as low as 0.1 m/s.

Multi-parameter Measurement: Simultaneous monitoring of temperature, pressure, and flow rate in a single device.

Wide Application Range: Supports stack diameters from 0.3-12 m, with customizable 2 or 4-channel configurations.

Non-contact Design: External probe mounting with corrosion-resistant materials for enhanced durability in harsh environments.

Strong Anti-interference: Autocorrelation detection technology effectively eliminates on-site noise interference.

Universal Compatibility: Suitable for acid and wet gas measurement, unaffected by gas composition changes.

Intelligent Processing: High-speed processor for rapid data analysis, with integrated calibration and diagnostic functions.

Specifications

Application

The ultrasonic flowmeter can be widely used in the flow rate and flow monitoring of pollution sources and discharge outlets in Wet FGD, petroleum, coal, electric power, natural gas, steel, building materials, chemical, petrochemical, textile, nonferrous metal, waste incineration etc.
