Sludge Transfer and Blanket Level

Sludge transfer flow and blanket level in settling tanks, where coating and low velocity defeat clean-liquid instruments.

Category
Sludge & Slurry
Standard lead time
7 working days for standard models; a sludge-blanket installation check adds 3 working days.
Package
3 recommended instruments

The problem at this measuring point

Sludge coats the sensor within days, so a clean-liquid meter drifts and then jams. The blanket level in a settling tank is a soft interface, not a clean surface, and an echo taken at the wrong gain reports the tank floor as sludge.

How we choose the principle

If the process is Use this principle
Sludge transfer line, solids present, conductive Electromagnetic flow meter with a non-stick lining
Solids and gas, low velocity, poor straight run Doppler flow meter, unmounted or clamp-on
Blanket level in a settling tank Ultrasonic sludge level meter, fixed-top installation
Level difference across a screen or a channel Differential level measurement with two sensors

Scope of supply

Aumeascon supplies the instrument and the stainless or coated mounting hardware. The site provides the tank or pipe access, the power supply and the 4-20 mA or Modbus connection. Clarifier structural work is outside the supply.

Sludge is where clean-liquid instruments go to fail. The medium coats, the flow is slow and non-uniform, and the number that matters is often a solids concentration rather than a volume.

Content plan — this package

  • Site photographs: one or two photographs of an installation of this package, so the mounting and the pipework are visible before the visit.
  • Measured results and case data: what the readings were before and after commissioning, and the permit or report the measurement now feeds.
  • The commissioning checklist: what the site prepares, what is checked on the day and what the handover record contains.
