Automatic Sludge Blanket Level Detector
This detector automates sludge removal in clarifiers and tanks by tracking liquid-solids interfaces. It reduces energy use and maintenance costs by operating pumps only when necessary. The system features automatic beam intensity adjustment for varying concentrations and works in confined spaces like lamella separators. Municipal and industrial facilities benefit from its reliability in diverse applications including DAF units and SBRs.
Suspended Solids Density Meter
This ultrasonic meter provides real-time %SS readings for sludge and slurries in pipes and tanks. It measures concentrations from 0.1% to 15% without nuclear components, making it safe and permit-free. The system automates pump operations to maintain optimal density while resisting interference from fluid color or particulates. Available as inline or throw-in models for different installation requirements.
Duckbill Automatic Composite Sampling System
This air-powered sampler collects influent/effluent samples in challenging conditions using compressed air instead of pumps. It operates in freezing temperatures and remote locations while meeting regulatory monitoring needs. The system handles high lifts and long runs without clogging, with explosion-proof construction and self-cleaning capabilities for reliable sampling.
Sludge Sleuth Detector
This compact detector provides single-point monitoring of sludge interfaces with adjustable sensitivity controls. It automates pump operations when sludge reaches set concentrations, featuring LED indicators and relay outputs. Designed for municipal and industrial clarifiers, it includes self-diagnostics and offers both rigid and hanging installation options for different tank configurations.
Sludge Gun Portable Detector
This battery-powered handheld device measures sludge levels in tanks, lagoons, and septic systems. It features audible density feedback through a speaker and thumbwheel sensitivity control for varying conditions. The weatherproof design includes cable markers for depth measurement and operates without calibration. Ideal for field technicians needing portable monitoring solutions.
