Optical Liquid Level Sensor Market Growth, Forecast and Value Chain 2015-2025: FMI Estimate


                

Optical liquid level sensor is a contact-type sensor used for point level sensing of organic, corrosive and aqueous liquids that exhibits upper free surfaces. Optical liquid level sensor works on principle of optical reflection and detects change in transmission of light emitted from light emitting diode (LED) mounted on infrared LED and infrared photo detector. Based on the presence or absence of liquid, change in transmission is sensed. Optical liquid level sensors are used to detect level of liquid-liquid interfaces and liquids with suspended solids. Optical liquid level sensors are comparatively Inexpensive as compared to other liquid sensing technologies.
