		<description><![CDATA[When we talk of liquid level sensors, we’re usually referring to tiny systems that are used to detect levels of liquids (like in the fuel tanks of automobiles).
These sensors are also used to detect interfaces between liquids like oil and water or between liquids and solids.
They can sense the level of liquids either continuously or at certain points following which certain alarms are triggered, like we see the red or yellow low-fuel light on the fuel gauge of a car.
Liquid level Sensors that are used for continuous monitoring depend on pressure, ultrasound or vibration, or a combination of any of these methods.]]></description>

		<description><![CDATA[Refrigeration, the process of maintaining an enclosed space at a temperature lower than the surroundings, has wide application in various industries like food processing, power plants, hospitals, pharmaceuticals etc. as well as for commercial use like supermarkets etc. The 3 main methods of achieving refrigeration are cyclic, non cyclic and thermo electric, out of which cyclic method is the most common.
The major components of cyclic refrigeration systems are compressor, condenser, evaporator and expansion valve that correspond to compression, condensation, evaporation and expansion part of the thermodynamic cycle respectively...]]></description>

		<description><![CDATA[Valves perform a variety of functions in refrigeration systems. They are used for expansion of vapour, regulating flow of water or vapour, pressure and temperature regulation, activating a device etc. Depending on the function there are various types of valves available viz. expansion valves, stop &#038; regulating valves, solenoid valves, safety valves, pressure controlled valves, etc.
Valve regulators are used for many different functions in commercial and industrial refrigeration like capacity regulation, condensing pressure regulation, evaporation pressure regulation, receiver pressure regulation, crankcase pressure regulation etc...]]></description>
