ultrasonic flow meter / for gas / wall-mount

Ultrasonic sensor system to measure the velocity and the volume flow of flue gas or process gas in pipes or ducts.
Two identical sensors transmit and receive ultrasonic pulses alternately. The flow velocity of sample gas is precisely calculated from the transit time difference dependant on the direction. Taking into account the cross-section of the stack, the gas temperature and absolute pressure the flow rate is calculated in parallel.
D-FL 220 performs automatic check cycles and requires extremely low maintenance.
In situ measurement, continuous measurement
Measurement even in wet or dust-laden flue gas
Allows calibration to measure the volume flow
Also suitable for thick-walled stone / insulated ducts
Automatic zero and reference point check
Sensors are purged and are therfore not in contact with sample gas
Easy installation, adjustment and maintenance
No separate control unit required
Normalization of the flow measurements as an option
Very low maintenance
