IN handling Liquids where a continuous rate of flow is an operating aid and necessity, it is desirable to know at a glance the rate of flow in GALLONS PER MINUTE.  With a clear Pyrex® tube entirely around the body and an indicator just inside the tube for easy reading, the rate of flow is observable at all times.  The flange of the float deflects the liquid against the wall of the tube and helps keep it clean and the indicator remains visible even in liquids of high sediment content.  The small size of the flow rater permits minimum line spacing.

Teleflo/Dial Type

Construction: Bronze

Pressure Rating: 125 PSI at 200°F

For many liquids, particularly dark or opaque, the Teleflo indicator with its easy to read, vane-actuated dial, indicates the relative amount of liquid flowing through a pipeline.  It can be installed in vertical or horizontal pipe lines, with flow in any one direction.

Requires at least 1/2 GPM minimum flow to ensure correct dial reading.

When the Teleflo is equipped with a microswitch and conduit connection, it can operate a bell, whistle or similar alarm.  When used in relay, it can be used to shut off a pump motor should the liquid flow stop.
