The measuring instrument operates based on the ultrasonic measurement method. Media contacting parts are manufactured using chemically resistant PVDF. This ensures that aggressive media can also be measured without problem. The instrument is installed directly in
the pipe of the medium being measured.
Interfering influences, such as air bubbles, are identified by the DulcoFlow® and forwarded to the analysis unit as an error message. The instrument, which is structured for wall mounting, is designed for a measurement range of 0.1 to 50 litres per hour.

Measuring principle
The DulcoFlow® flow meter measures the volume flow of pulsing flows. The ultrasonic, time of flight measurement
method is used. For the time of flight measurement, a sound signal is alternately transmitted in and against the
direction of flow. The time difference is then a measure of the mean flow velocity.
Use of the ultrasound measurement method automatically compensates any temperature induced changes in the
medium. Operation without moving parts guarantees a long service life and wear-free operation.
