Description

The TRUFLO switch ensures protection against flow changes that could be detrimental to equipment and processes. The TRUFLO functions by diaphragm action brought about by a flow through a calibrated nozzle. The movement of the diaphragm is used to operate a microswitch.

The underside of the diaphragm is in direct contact with the inlet flow, the upper side with the outlet flow from the calibrated nozzle. With no flow through the TRUFLO a spring loaded plunger holds the diaphragm in the down position.

Flow through the calibrated nozzle causes a pressure differential between top and bottom of the diaphragm, with the higher pressure on the underside of the diaphragm, pushing it upwards. This in turn causes the plunger to move, which changes over the microswitch.
