Sludge Blanket Level Measurement

Transcription

1 Sludge Blanket Level Measurement Entech Design Inc. manufacture high quality sludge level detectors, interface level analyzers and underwater material profiling systems. Continuous level measurement in 1 to 4 tanks with a single analyzer and multiple sensors provide cost effective solutions in plants of all sizes. Patented dual-axes scanning systems address the demanding requirements of coal-fired power utility boilers. Systems are engineered to meet the unique requirements of the industries in which they are applied. System operating frequencies are selected for the specific requirements of light-density suspended solids typical to Water and Wastewater clarifiers and thickeners. Lower frequency systems are applied in industrial applications with greater solids concentrations and agitation in the settling zone. Superior signal analysis and tracking intelligence is engineered into every system, and performance is proven in extensive field installations. Contact us for a product demonstration in your application! BinMinder 9300 TM provides superior sludge level detection in the full range of water and wastewater clarifiers and thickeners. It's the only system that integrates higher frequency underwater acoustics with advanced 32-bit microprocessor technology designed specifically for lightdensity sludge. BinMinder 9300 TM is the only interface level analyzer successfully adapted to the demanding requirements of dissolved air flotation thickeners for reliable floating scum depth measurement. And, no other instrument is as effective in water treatment clarifiers and sedimentation basins as BinMinder 9300 TM. Effective clarifier and thickener control demands dependable sludge level measurement. BinMinder 9300 TM provides information you can rely on! For Raw & Waste Water Clarifiers, Thickners & DAF Plants Multi-channel system provides cost-effective measurement in 1-4 tanks. Simple upgrade path by field addition of extra sensors. Integral, multi-function graphical LCD provides ready access to current measurements, tank echo-profile display, and convenient set-up menu. Automatic Initialization and Automatic Gain features make set-up and operation extremely easy - enter Tank Depth and Zero Adjust (offset for sensor elevation) and BinMinder 9300 TM does the rest! Self-cleaning transducer option (with integral stainless steel wiper) guarantees continuous operation long after others have failed.
