A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float. Another common type is a float that raises a rod to actuate a microswitch.
A float ball (in orange color) Liquid level floats, also known as float balls, are spherical, cylindrical, oblong or similarly shaped objects, made from either rigid or flexible material, that are buoyant in water and other liquids.
Magnetoresistive level sensor. Magnetoresistance float level sensors are similar to float level sensors however a permanent magnet pair is sealed inside the float arm pivot. As the float moves up the motion and location are transmitted as the angular position of the magnetic field. This detection system is highly accurate down to 0.02° of motion.

Magnetic float level sensors involve the use of a permanent magnet sealed inside a float whose rise and fall causes the opening or closing of a mechanical switch, either through direct contact or in proximity of a reed switch. With mechanically actuated floats, the float is directly connected to a micro switch.
Tidal poles and float gauges were the primary means of sea-level measurement for over 150 years and continue to operate at some locations today. While still part of modern-day tide gauge instrumentation, these technologies have since been superseded by pressure gauges (similar to depth gauges ), acoustic/ultrasonic gauges, and radar gauges.
Since the parasitic capacitance of the sensor is related to the electric field's (E-field) path to ground, it is important to choose a ground plane that limits the concentration of E-field lines with no conductive object present. Designing a capacitance sensing system requires first picking the type of sensing material (FR4, Flex, ITO, etc.).
The weight of a float is about 20 kg without sensors. Floats can carry a variety of sensors to collect data. A common sensor used is a CTD to collect data about the conductivity, temperature, and depth (which is related to pressure). The salinity can be calculated from the measurements taken by the CTD.
