Liquid level float switch TDFS Series

Product Overview

The liquid level float switch is an automatic level control device with a simple structure and reliable performance, designed for monitoring and controlling liquid levels in various media. Its operating principle is based on buoyancy and mechanical transmission: the float moves with the liquid level, driving the internal switch to automatically trigger alarms or control equipment operation. The product features easy installation, high stability, and strong anti-interference capability, making it widely applicable in liquid level management for water supply, drainage, storage tanks, and industrial equipment.

Core Functions

Liquid Level Linkage Control: The float adjusts its angle with liquid level changes, directly activating the internal micro switch to automatically switch between high and low liquid level states.

Automatic Pump Control: Enables automatic start/stop of water pumps based on liquid level, facilitating autonomous drainage or water replenishment operations.

High/Low Level Alarm: Triggers an immediate switch signal when the liquid level reaches preset thresholds, activating audible/visual alarms or transmitting signals to the control system.

Dry-run Protection: Automatically cuts off equipment power during fluid depletion to prevent pump damage from dry operation.

Application Areas

Water Supply and Drainage Systems: Automatic water supply for tanks/towers, basement drainage control

Industrial Process Control: Chemical tank level monitoring, boiler water level management

Environmental Treatment Equipment: Water level control in wastewater treatment plants, rainwater recycling systems

Agricultural Irrigation: Automatic replenishment for reservoirs, irrigation system water source management
