Point Level Sensor Types from Monitor Bin Level Switches. Level sensors are used to detect liquid or powder levels, or interfaces between liquids. they are an important part of a fluid system because the position and displacement of an object or media is critical to know in many applications. Вђў flow--many types of flow meters convert flow to pressure or displacement, using an orifice for volume flow or coriolis effect force for mass flow. capacitive sensors can then measure the displacement. вђў pressure--a diaphragm with stable deflection properties can measure pressure with a spacing-sensitive detector. вђў liquid level --capacitive liquid level detectors sense the liquid level.


Level switches can also be designed to detect the level of solid materials such as wood chips, grain, coal, or animal feed in a storage silo, bin, or hopper. a common design for this application is a small paddle wheel, inserted into the bin at the desired height, which is slowly turned by a small electric motor. when the solid material fills the bin to that height, the material prevents the semrad has over 20 years of experience in providing the australian industry with high quality, highly reliable level measurement. by using equipment such as our level switches and level transmitters, we are able to create entire systems that have been tailored to your application.

The float level measurement technology is the most simple, reliable, and economical technology on the market. for a typical pump automation, it is necessary to use two floats level switches: a first float switch to start the pump, and a second one to stop it. level sensors are used to detect liquid or powder levels, or interfaces between liquids. they are an important part of a fluid system because the position and displacement of an object or media is critical to know in many applications.
