pressure sensing technology, the
Sensor provides the most accurate and non-
intrusive flow verification device to date.
Without any moving parts in the sensor, the
standard flow path of the pump is preserved
and the liquid does not move through any gears
or lift a magnet to actuate a pulse in the sensor.
This eliminates any concern of plugging,
leaking or jamming of the flow path or sensing
mechanism.

The OSI OSI will send out a signal with every stroke as long as there is liquid pumping against
LOW
pressure. If the pump becomes either air-locked or in a dead head condition, the sensor will no longer
output a signal. And unlike the competition, if the discharge line breaks or becomes disconnected,
pressure will be lost and the
