Monitoring Equipment for fluids

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
m/s.
