Automatic Sludge Blanket Level Monitoring with continuous output, simple operation and low cost of ownership.

Ideal For: Final settlement tanks, Clarifiers, Primary settlement tanks

The ASLD 2200 is a fully automatic sludge blanket level detector primarily designed for the water and waste water industry but could be applied to other types of process. It utilises a servo-driven sensor which continually tracks the settled interface and produces a 4-20 mA output which is proportional to the depth of the blanket. The ASLD 2200 is supplied with either a Infrared or Soli-Tech 20v2 sensor. The use of infrared attenuation as the principle of operation for the sensor allows Partech to ensure sufficient sensitivity to monitor sludge blankets in a wide variety of applications. It should be noted that sensor selection can be site dependent, Partech are happy to provide full support in the selection of the correct sensor.

The sensor will normally be in the area of the tank just above the sludge and will therefore be kept away from the worst of the fouling that can occur in the treatment of either potable or dirty water. Provision must be made for transmission of the output signal to the control system; this is normally possible via spare slip rings. Where this is not possible a radio telemetry option is available, allowing transmission directly to the control system without the need for installation of cables.
