The Compact Displacer Level Switch for Water is an economical and efficient option for controlling water levels in atmospheric storage tanks. It uses the buoyancy principle to detect water levels and is designed for easy installation and minimal maintenance.

Compact Displacer Level Switch

Compact Displacer Level Switch

The Compact Displacer Level Switch is composed of two displacers spaced at appropriate intervals and suspended via a rope, which are connected to a coupler rod with an actuator for on-off switch operation.

When the water level rises and reaches L1 (high level), the top displacer submerges into the water, generating a buoyant force that moves the actuator upwards to trigger the micro switch. Conversely, when the water level falls and reaches L2 (low level), the actuator lowers due to the reduced buoyant force, causing the microswitch to release.

To adjust the control range to suit specific applications, the spacing between the displacers can be modified to reposition them to the desired location on the rope. The Compact Displacer Level Switch is a reliable and efficient solution for controlling water levels, providing accurate and repeatable switch operation.

Installation of Compact Displacer Level Switch

Installation of Compact Displacer Level Switch

During installation, the Compact Displacer Level Switch can be either flange-mounted on the tank top or bracket-mounted on the tank side wall. It is important to take the necessary precautions to prevent any restrictions on the displacer movement caused by the tank internals.

The switch should be mounted at a distance from the inlet and outlet of the tank flow to minimize the effects of turbulence and suction. By adhering to these guidelines, the Compact Displacer Level Switch can be installed securely and optimally for reliable and accurate level control.

Displacer Switch Wiring

To enable pump on-off control during tank fill and drain operations, the Compact Displacer Level Switch must be properly terminated and wired. This involves connecting the microswitch of the switch to the pump control panel through suitable cables while ensuring that all connections are secure and properly tightened.

This will enable the level switch to effectively control the pump operation based on the level of the water in the tank, ensuring efficient and effective water management.
