Level Switches, Float Switches & Sensors
About our Level Switches, Float Switches & Sensors
Level switches are critical components in a wide range of industrial and commercial applications. These devices are designed to monitor changes in liquid or gas levels and flow rates, enabling precise control and efficient management of systems and processes. Their reliability and accuracy make them essential in ensuring safety, preventing overflow or dry running, and maintaining optimal operational performance.
What is a Level Switch?
A level switch is a versatile device used to detect the level of a liquid or solid material within a container, tank, or silo. When the material reaches a predefined level, the switch activates to trigger an action, such as sounding an alarm, controlling pumps, or opening and closing valves.
What is a Float Switch?
A float switch is a specialised type of level switch that uses a buoyant float to detect the level of liquid in a tank or container. As the liquid rises or falls, the float moves with it, triggering the opening or closing of an electrical circuit to activate the desired action, such as starting or stopping a pump.
Float switches are commonly used in water tanks to control filling and prevent overflow, sump pumps to activate automatically as water levels rise, and liquid storage systems to maintain proper levels in industrial and domestic applications. These simple yet reliable devices are valued for their ease of use, cost-effectiveness, and versatility across various environments.

Frequently Asked Questions
- What is the Difference Between a Float Switch and a Level Switch?
-
Float switches are a specific type of level switch that use a buoyant float to detect liquid levels, while level switches can use technologies like capacitance, ultrasonic waves, or conductivity to monitor both liquids and solids. Float switches are ideal for basic liquid level detection in water tanks and pumps, whereas level switches are more versatile, offering advanced options like continuous monitoring and use in complex or hazardous environments such as chemical processing or food manufacturing. Understanding these differences is key to choosing the right solution for your application.
- What is a Water Sensor?
-
A water sensor is a device designed to detect the presence, absence, or level of water in a specific environment. These sensors use various technologies, such as conductivity, capacitance, or ultrasonic waves, to monitor water levels or detect leaks. When water is detected or reaches a predefined level, the sensor sends an electrical signal to trigger an action, such as activating a pump, shutting off a water supply, or raising an alert.
- How Accurate Are Level Switches?
-
The accuracy of a level switch depends on its type, design, and the specific application in which it is used. Generally, level switches are designed to provide reliable point-level detection rather than continuous level measurement, and their accuracy is typically sufficient for most industrial, commercial, and residential applications.
