Vane Type Liquid Sight Indicator

Utilizes a single observation window and a flow activated vane to furnish a constant readout of liquid flow, clarity and color (this one has an amber lens).

You can possibly order a clear lens from Kaydon (possibly P/N 88460).

Spring actuated vane.

Observation of vane positioning gives an approximate indication of the rate of flow. The vane assumes a position at right angles to the center line of the pipe when there is no flow, and moves at an oblique angle when liquid is flowing.

Designed for easy observation of flow from either the right or left, up or down.

Brass construction with wire brushed exterior finish.

Withstands a working pressure of 125 PSI.

Standard heat treated glass window meets MIL-G-2697 and is furnished with the unit.
