Level measurement is an integral part of process control, and requires continuous and accurate measurements
under all conditions. Optech tested its Sentinel 3100, a NEMA 4 laser level monitor, at a large public utilities
department. It is important to know the water level in the surge compensation tanks; the water has to be above a
certain level before the pumps can cycle on or else the pumps can be damaged by pumping air. Other technologies
were unsuccessful because of the narrowness of the tanks, and since nothing could be placed inside the tanks, the
sensor had to be non-contact. The Sentinel 3100 measured successfully to the water surface inside the tank. When
compared to a tape measure, the results agreed favorably.
