Use The flow sensor is suited to continuously measure flow or monitor liquids such as hot water, heating water, or standard water-glycol mixes in HVAC plants and applications. The sensors can be used in automation and control systems as control sensor or measured value sensor.

Note mounting position and flow direction Mount the flow sensor only in the intended position or proper flow direction (note the arrow on the connecting pipe). The measured flow values will be wrong if the sensor is mounted in the wrong position or direction. 15 97Z0 4 Install the flow sensor where the pipes are completely filled with the medium to be measured, and where gas bubbles and cavitation in the medium are avoided. 0° .
