It is mostly used in construction sites for surveying. Laser level measurement devices can work with variety of materials such as bulk solids, slurries, and opaque fluids like dirty sumps, milk, and liquid styrene etc. Just like an ultrasonic sensor, a laser transmitter is also mounted at the top of the tank which then directs a short pulse of light in downward direction towards the surface of the process liquid. This light is then reflected back to the sensor. The measurement system includes a timing circuit which is used to determine the time taken by the light signal to return back and hence finds out the distance between the sensor and the process material.
