Mobrey™ MSM400 Series Ultrasonic Suspended Solids Monitoring and Control System

Mobrey

To run at your full potential and maximize process control, you need reliable level instrumentation throughout your facility. The Mobrey MSM400 system continuously monitors the suspended solids or sludge density contained in, or flowing from, a clarifier or settlement tank during de-sludging. Many years of practical experience have shown that measurement of ultrasonic attenuation in a slurry is directly proportional to the percentage of suspended solids.The MSM400 system uses this principle to produce a digital display of the suspended solids measurement.
