What is a Level Switch?
Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a peak.
The substance to be measured can be inside a container or can be in its natural form (e.g., a river or a lake). The level measurement can be either continuous or point values.
Continuous-level sensors measure the level within a specified range and determine the exact amount of substance in a certain place, while point-level sensors only indicate whether the substance is above or below the sensing point. Generally, the latter detects levels that are excessively high or low.

What are the advantages of level switches?
Advantages and Disadvantages
These switches are economical so used for monitoring, controlling & changing liquid levels. Each switch needs raw materials in the manufacturing procedure of control to keep away from waste. The bulk storage control & liquid materials helps in avoiding waste from spillage & overflows.
How accurate are level switches?
The accuracy of GEMS level switches is ±1/8˝ (3.2 mm) of true liquid level. In order to assure the proper accuracy for your liquid, please specify the specific gravity of the media. GEMS will automatically calibrate for the submergence of the float, based on this specific gravity information.
What is the most reliable level switch?
Float switches
Float switches are cost-effective and reliable level switches that can be used with a wide variety of media
Is a level switch analog or digital?
Level switches can have displays that are analog, digital or video displays. Control for the devices can be analog with switches, dials and potentiometers; digital with menus, keypads and buttons; or controlled by a computer.
