The Smart Diver is a ruggedised mud diver that provides measurement of mud levels, settling zones and overflow clarity in thickeners, clarifiers, washers and decanters. Tank profiling (suspended solids vs depth) is also provided, as it is specific gravity profiling and bed level measurement. For more information call +61 3 9786 1711.

Instrumentation and Control of Sedimentation Equipment

Some of the process variables that are commonly monitored on a thickener are torque, rake height, bed level, bed pressure, feed rate and density, underflow rate and density, settling rate, and overflow turbidity. Many of these are easily measured, while some can be difficult.

Tailings Thickeners | Hawk Measurement Systems

The Sonar Acoustic transmitter can be calibrated to work with two different densities. We can track the Compact Bed Level to control the underflow pump. We can also track a lighter density within the interface column that when affected by a settling problem with in the Thickener will rise hydraulically upwards towards the launders.

An intelligent control strategy for thickening process ...

10-09-2015· Through the online measurement of the thickener operation parameters including feed flow rate, mud bed level, and underflow concentration, an intelligent control strategy for thickener underflow and flocculant addition is proposed based on the mass balance model and expert rules.

Sludge level sensors and transmitters for sedimentation ...

To measure sludge level where clogging and fouling can occur (primary and secondary clarifiers, sludge tanks, thickeners, etc.), we recommend sensors with a wiper. For sludge level measurement in a secondary clarifier that has a surface skimmer or in clear water sedimentation tanks, you can use a standard sludge level detector.

Instruments for bed level detection - Coastal Wiki

Acoustic bed level detection (echo-sounding instruments) The most common system for measuring water depth is the single-beam echo sounder. This sonar instrument uses a transducer that is usually mounted on the bottom of a ship. Sound pulses (usually 210 KHz for surface detection) are sent from the transducer straight down into the water.

How to Use | Thick-It

Add level measured thickener into a dry, empty glass. Pour entire amount of desired cold or hot liquid into glass over thickener powder. Immediately begin stirring briskly with fork, spoon, or whisk for 30 seconds to 1 minute. With water and juices, let stand for 1-2 minutes and serve. With milk and supplements, let stand for 3-6 minutes and serve.
