Interface Level Analyzers


Royce now offers a complete line of Interface Level and Point Level Analyzers that make it possible to reliably monitor and control the solid/liquid interfaces in settling tanks and clarifiers; regardless of the size of the plant, process or budgetary constraints and now all analyzers measure and output Clarity as well.

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.

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 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
