Introduction

Gasboard-7900 is a high temperature ultrasonic flowmeter independently developed by Cubic Instruments. Based on the TOF (Time of Flight) principle of ultrasonic wave, one or more pairs of ultrasonic transmitting and receiving devices are installed in the direction of the upstream and upstream of the medium respectively, and 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 field and uneven flow velocity distribution in the pipeline, and 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

• Suitable for acid or wet gas flow measurement, measurement result is not affected by gas composition changes.

• Large measuring caliber range, support 0.3-12m stack diameter.

• Ultra-low flow rates measurement with lower detection limit of 0.1m/s.

• It can be flexibly configured according to requirements, and one or more ultrasonic transceivers can be used for measurement.

• Corrosion-resistant materials are used in the gas contact part of the whole machine, which can be used under high temperature and corrosion conditions of flue gas.

• Using high-speed data processor for faster running speed, and equipped with functions of calibration, configuration, query, diagnosis and others.
