Sight-Rite™
Fluid Flow Indicator

The Sight-Rite™ flow indicator is highly recommended for applications where visual inspection is critical and liquid output is required. It is designed to enhance the already reliable PurgeX® 1/4" piston line of injector pumps. The Sight-Rite™ couples the reliability and precision of an electric indicator with the simplicity of a flow sight. It permits checking of fluid flow at a glance via a green LED light.  It is ideal wherever a simple and economical fluid flow indicator is required.

Sight-Rite™ is compatible with the Air Operated PurgeX® liquid delivery injector pump.  Each injector pump can precisely deliver an output range from zero to .009 cubic inches per cycle.  Due to small volumes of fluid dispensed, an operator may not be able to visually determine whether or not fluid is being dispensed.  Additionally, the operator may not be able to safely inspect a lubrication point in distant areas or near rotating equipment.  The Sight-Rite™ indicator quickly and safely confirms that fluid is being dispensed, and each pulse of liquid cycled through the Sight-Rite™ activate the indicator light.  The Sight-Rite™ thus provides added security that fluid is being applied in critical applications.

The construction is sturdy and compact. Bodies are manufactured from rugged epoxy and acetyl to resist chemicals and solvents. The internal mechanisms are constructed from brass and stainless steel to resist rust and corrosion under the most adverse conditions. The versatile units are capable of detecting flow for fluid viscosities from SAE 10W through SAE 50W oils.

Each Sight-Rite™ is supplied with a high-efficiency green LED that is daylight visible and powered by a button cell battery source.  The Sight-Rite™ flow indictors are supplied with 1/8-FNPT connections at the inlet and outlet.  The Sight-Rite™ is ideal for an entire facility or a single application.
