Suspended Solids Density Meter

Markland's Meter monitors silt/sludge concentrations in pipes, clarifiers & tanks, and automates de-sludging, using the inherently safe attenuation of non-radioactive ultrasound (no permits, no approvals required).

This instrument helps Utilities/industrial water & wastewater plants by measuring primary, secondary, return-activated and backwash sludge. It allows users to program underflow pumps to automatically shut off before sludge becomes too thin, and helps determine polymer dosages for improved filter press/centrifuge/digester performance. These efficiencies improve the outflow available for reuse.

Percentage suspended solids readings are continuously sent to a computer/control system, enabling calculation of mass flow rate. By observing changes in density, operators may also gain early awareness of breaks in filtration material. Readings are not affected by the colour of particulates or fluid.

The inline pipe spool-piece sensor is non-intrusive and supplied in various pipe sizes and materials (including PVC and carbon/stainless steel). A throw-in style probe is also available, which can be used as a single point interface level detector as well, allowing operators to program de-sludge pumps to turn on when the rising sludge blanket contacts it. Each style is simple to install, calibrate and clean.
