Level Switches & Transmitters
Devices used for monitoring and controlling liquid levels in water storage tanks, reservoirs, and various industrial processes are absolutely essential to ensuring the safety and efficiency of these systems. Among these devices, level switches and level transmitters play key roles. In using liquid level switches, one would typically sense either the presence or the absence of a liquid at a specific level and then send an on/off signal to some control device when the liquid hit a defined point. Things like pumps, alarms, or other control systems could be used to "do something" when the liquid level reached that defined point.
In contrast, we have the level transmitters, which send data to indicate the level of the liquid in a tank. These devices work well in the application of accurate level measurement in tank monitoring. They provide a nice continuous level measurement. They give an accurate measurement of the liquid in the tank, and they do it over an extended range. This is why you will find these devices used in process control, wastewater treatment, and the food and beverage industry. They give accurate measurements even in hazardous environments. They give satisfactory performance even with process fluids that are difficult to measure—like those with a range of viscosities or that have a density different from water.
