S/85

The Model S85 is an active device which is designed to give an alarm signal if fluid falls below a preset level. It will only signal an alarm after a few seconds of low level to eliminate false alarms due to turbulence.

The fact that the Model S85 has no moving parts and incorporates a built in delay means it is ideal in appliations where mechanically operated switches mis-trigger due to vibration and fluid turbulence.
