Sludge Interface Measurement

Sludge blanket level measurement is the technique of measuring the boundary between two material densities e.g. water and a slightly higher density sludge.

Sludge Blanket Level Detector

Pulsar’s Sludge Finder 2 is a controller and transducer system that provides reliable continuous sludge blanket level measurement. It is used in thousands of applications worldwide for detecting sludge blanket levels in primary, secondary, tertiary settlement tanks either with stationary or travelling bridges, clarifiers, gravity thickeners or sequencing batch reactor (SBR) systems.

Radio Telemetry System

Pulsar’s Radio Telemetry System is available as either a stand-alone transmitter or fitted internally into a Sludge Finder 2 controller. It transmits the information from up to two 4-20mA output signals and two relays to a matched receiver unit. Units are paired so an unlimited number of pairs can be used in the same location and transmission security is assured by ‘frequency hopping’ and a visual signal strength indicator.

Pump Control

Pulsar’s pump controllers offer a variety of control routines depending on the level of pump automation and management you require. Ranging from simple pump control routines such as duty assist and duty back-up to more advanced routines such as pump efficiency, predictive maintenance and pump reversing.
