Due to its reliability, a float switch is one of the most frequently used measurement technologies for monitoring liquid media levels. Its simple yet effective design consists of a hollow float within a guide tube, rising and falling with liquid levels and activating switches along the way.

The float switch FTS20 is a simple and cost-effective solution for point level detection in appropriate fluids. It is used in tanks and vessels as a pump protector or level alarm in open basins, like in sewerage treatment plants. The float switch has two output options, a NAMUR switching signal or a change-over contact.

Aug 21, 2015 · Float switches and other liquid level sensors are devices designed to measure the depth, volume, or other metrics in a tank or vessel. Most commonly used to control or measure the flow of liquid in or out of the vessel, as with sump pumps or fuel level gauges, liquid level sensors can be found in a variety of different forms being used for ...

Float switches are highly effective at detecting point-based limit levels for one or more switch points. WIKA’s portfolio has a float switch for almost all liquid media and interfaces, regardless of foaming, conductivity, pressure, vacuum, temperature, vapors, condensation, boiling effects, turbulence, corrosion, or vibration.

We recommend our float type level switch for low cost liquid measurement. The principle of float type level meter is that a float moves up and down due to buoyancy. A reed switch in a stem is actuated by a magnet in the float, and outputs detection signal (see the figure below).

Mar 16, 2018 · The best option for high viscosity liquids is to opt for non-contact options like optical or ultrasonic level sensors for accurately measuring liquid levels. Here’s why: Acoustic waves emitted by ultrasonic liquid level sensors and the measuring of the echo returned, make it possible to know liquid levels without ever having to physically ...

Feb 12, 2018 · Ultrasonic level sensors work by using sound to measure liquid or solid media. These sensors emit a high-frequency pulse outside of the human hearing range and then measure how long before the sound is returned. If low cost tops your list of requirements, then reed switches may be the best option.

The float-type liquid level switch is a simple, easy-to-use, safe, and reliable liquid level controller. It operates faster and has a longer service life compared to general mechanical switches. Compared to electronic switches, it has strong load impact resistance and can achieve multi-point control with a single product.

Oct 11, 2024 · Liquid level switches play a crucial role by offering reliable monitoring and control. They detect the presence or absence of liquid in tanks or pipelines, providing critical information for smooth operations. In this guide, we’ll explore three popular types of liquid level switches: float, capacitive, and tuning fork.

Oct 26, 2023 · Point float level sensors, also known as float switches, are used to detect the presence or absence of liquid at a specific level. They can be used to trigger alarms, pumps, or other control actions. Point float level sensors typically use a single or multiple reed switches that are activated by a magnetic float when the liquid reaches the ...
