Ultrasonic stack gas flowmeter
April 2011
Flow Measurement & Control
Durag’s D-FL 200 volume flowmeter is an ultrasonic measuring system operating on the differential transit time principle. The system provides continuous in situ measurement of flow and velocity in flue gas. It is specifically designed for flow monitoring below the dew point in aggressive gases.
Automatic zero point and reference point control is possible, while options for temperature and pressure correction are available. The sensors are completely separated from the gas by means of purge air.
The transducers transmit and receive impulses continuously, while the gas flow alters the transit time. The time upstream is reduced and the time downstream is prolonged. The system meets IP65 protection requirements. The length of the measuring range is up to 8 metres with a maximum operational temperature of 200°C.
High limit values are indicated immediately, permitting timely intervention by the plant’s control system in order to comply with prescribed emission values. The system is programmed using keys on the evaluation unit or via the PC.
