3.6.1 Installing FlowSensor
The Solaris FlowSensor FLS20 (image 3-40, 16 41 07), available as an accessory, is a measurement instrument that
records the flow volume in the solar panels and the feed temperature. The measurement range of the FlowSensor FLS20 is
between 0 and 20 l/min (flow volume) and 0 to 120 °C (feed temperature). The measured values are shown in the display of the
Solaris RPS3 P2 control and pump unit. Thanks to the speed control of the tank circulation pump, the Solaris RPS3 P2 control
and pump unit automatically adjusts the passing flow during operation.
