compact flow sensors

The compact SN 450 range of flow sensors have a linear analogue 4-20 mA output. This
 provides the user with a measure of the flow velocity that can be calibrated. They are
 suitable for use when monitoring the flow of liquids. The probe must be positioned in the
 pipe in such a way that the tip is fully immersed in the medium. With the largest flow, the
 instrument is set to an initial current of 20 mA by means of the trimming potentiometer. If
 there is no flow, the output current will be 4 mA. The largest detectable flow speed is 1.5

Measuring range/Adjustment information

The SN 450 GA is preadjusted at the factory to a detection range of 5-150 cm/s. The steepness of the characteristic curve can be changed with the potentiometer in such a way so that even a flow speed of e.g. 50 cm/s an output current of 20 mA can be reached.

In order to do this the potentiometer is turned clockwise while there is a pre-determined flow until the desired final value is reached.
