The Royce series of Interface Level Analyzers use an ultrasonic ranging technique to measure the depth of interfaces within the tank. The 25 series sensors are available in polyurethane for standard applications and Kynar for high temperature or chemical applications.
A Stainless Steel sensor is available for explosion proof applications. The sensor is mounted just below the surface of the water. Royce offers a hinged bracket sensor mounting option that accommodates surface skimmer passage automatically with the rotation of the rake.
The Model 2501A is a low-priced instrument designed for interface monitoring applications which does not require Speed of Sound Correction.
The Model 2511A is capable of having the ultrasonic speed of sound signal from its transducers changed by the user in applications where liquid mediums other than water are in use. It also has four setpoint relays which can each be used as either a “high” or “low”
setpoint. A serial output is available on both Models for the purpose of tying a number of the units to a central process control computer.
The Model 2505 system incorporates all the features of the Model 2511A allowing individual monitoring and control on every primary, secondary, and Thickening clarifier in the plant - economically.
The economical Series 2100 Point Level Detectors consist of the Model 2110 Single Channel Detector for single point optical interface detection where control setpoints allow the user the keep the interface in a single location.
The Model 2120 Dual Level Detector allows for the user to control the interface between two levels in the clarifier.
