Simple Operation • “Flow - No Flow” Switch
Use for both oil flow and water flow indication

Description
The TELEFLO is a rugged flow switch designed for a wide range of oil and water flow applications. For over 50 years, the TELEFLO flow indicator and switch has provided equipment protection against the loss of flow, protecting thousands of installations against costly equipment damage due to inadequate liquid flow.

Applications:

  • Bearing Lube Oil
  • Gear Box Lube Oil
  • Machine Tool Coolants
  • Cooling Water Lines
  • Seal Water

Features

  • Spring loaded vane actuated by liquid flow is connected to a red dial pointer that indicates a liquid flow reading on a graduated scale.
  • Switch is set by the factory, causing switch operation when the red dial pointer advances 1 1/2 + 1/2 graduations from the rest or no-flow condition.
  • The TELEFLO is a low flow switch. No adjustments are needed if the application requires a low flow switch.
  • After the TELEFLO is in operation, the switch cam may be accessed and adjusted for a different switch setting (most applications do not require any adjustments).
  • Complete liquid flow control is obtained by installing two TELEFLO flow switches in a series. The first in the series is set as a low flow switch, and the second in the series is set as a high flow switch.

Operation
The red dial pointer and switch are located in the head casting. The spring loaded vane is set in motion by liquid flow in the body casting. The vane rotates the red dial pointer and switch cam as liquid flow moves against the vane. The vane shaft connected between the head casting and body casting are sealed with a Viton “O” ring. The removal of the four cover screws permits easy access for connecting to switch terminals or cam adjustments. The factory sets the switch causing switch operation when the red dial pointer advances 1 1/2 + 1/2 graduations from the rest or no-flow condition.

The fluid enters in at the inlet and moves against the spring-loaded vane. The vane shaft connected to the red dial pointer rotates according to the amount of fluid advancing against the vane. The movement of the red dial pointer indicates fluid flow. The vane shaft also operates a cam that activates a SPDT switch.
