PRODUCT DESCRIPTION
PPPPOSI
The
metering pump is truly moving liquid into the
system and has not lost prime. Utilizing
proprietary circuitry coupled with advanced
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.

Additionally, a visual green LED is mounted

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
OSIFLOW will send out a signal with every stroke as long as there is liquid pumping against

SAFETY & CAUTION NOTES
Wear Protection
When working on or around a metering pump,
always wear proper protective clothing and
equipment as recommended by the supplier of the
chemical being pumped.
Remove Power
Disconnect the pump and sensor from their electrical
power sources before performing any maintenance.
If the pump starts operation during maintenance,
chemical may be sprayed & cause injury.
Application of Product
Use the PosiFlow within the specified range.
Using the PosiFlow in any other application than its
intended purpose may result in personal injury or
damage to the product.
Not observing precautions may cause injury or damage to the product.

*The
OSIFLOW Sensor requires a minimum of 30PSI
OSIOSI
total back pressure. If this is not available, the injection
valve supplied with the pump can be retrofitted with an
optional high-pressure spring, part number E90375.
This spring will increase the back pressure at the pump
approximately 50PSI.
