Level Switches, Float Switches & Sensors

Level switches and flow switches are essential components in industrial and commercial applications. These devices monitor changes in liquid or gas levels and flow rates, enabling precise control of systems and processes.

At Applications Engineering, we offer a comprehensive range of high-quality level switches and flow switches to meet diverse customer needs. Our products are designed to ensure dependable performance, even in challenging environments.

What is a Level Switch?

A level switch is a device that detects the level of a liquid or solid in a container. It can trigger alarms, control pumps, or operate valves when the material reaches a specific level. Common applications include water treatment, chemical processing, and food manufacturing.

What is a Float Switch?

A float switch is a type of level switch that uses a buoyant float to detect liquid levels. As the liquid rises or falls, the float moves with it, opening or closing a circuit to trigger an action. Float switches are ideal for water tanks, sump pumps, and other liquid storage systems.

How Does a Float Switch Work?

The float moves with the liquid level, either rising or falling within the container. This movement causes the internal contacts of the switch to open or close, signalling an action such as stopping a pump or raising an alert.

How Does a Water Level Sensor Work?

Water level sensors monitor the liquid level within a tank or reservoir using technologies like capacitive or ultrasonic sensing. When the water reaches the pre-determined level, the sensor signals the system to take action, ensuring safe and efficient operations.

Types of Level Switches Available

• Plastic Level Switches: Lightweight and resistant to non-corrosive liquids.
• Stainless Steel and Alloy Level Switches: For harsh environments where corrosion resistance is critical.
• Adjustable Tank Level Switches: Offering flexible actuation points.
• Optical and Solid-State Level Switches: Ideal for non-mechanical, high-precision measurements.
• Marine and Pump Level Switches: Designed for demanding marine and industrial applications.
