Waste water

Multi-beam suspended solids sensors for clarifiers, DAFs, and effluent compliance. No wipers. No drift. No fuss

Reliable turbidity and suspended solids monitoring that stays accurate without constant maintenance. Quadbeam’s multi-beam sensors measure the ratio between light paths, so fouling affects all beams equally and the reading stays true. No glass lenses to break, nomechanical wipers to replace. Calibrate on-site against your own lab samples for readings that correlate directly with your compliance data.

Key features:

Listening to nature’s voice

Self-compensating

The multi-beam ratiometric sensor virtually eliminates drift due to contamination or electronic ageing.

Listening to nature’s voice

Built for harsh environments

·One-piece polymer body designed for continuous submersion. No sapphire or glass windows to scratch, foul, or crack.

Listening to nature’s voice

Simple to install and maintain

Mount, wire to your controller, calibrate once against a grab sample. Most installations take under two hours. Standard 4–20mA output.

Right sensor for your process

From low-level effluent monitoring through to high-solids RAS and sludge applications.

Where to apply Quadbeam sensors for maximum efficiency

Applications include:

  • Clarifier optimisation - real-time turbidity and suspended solids data for chemical dosing and sludge blanket control to reduce waste
  • Final effluent compliance - continuous monitoring at the discharge point
  • DAF monitoring - measure solids removal to optimise air-to-solids ratios and lower energy costs
  • RAS/WAS monitoring - track sludge concentrations for consistent biology for plant stability
  • Influent and service water - characterise incoming loads for process planning
  • Industrial pre-treatment - verify trade waste discharge meets consent limits for accurate compliance.
