Ultrasonic Sludge Blanket Level Meter

Ultrasonic Sludge Blanket Level Meter – Overview

The Ultrasonic Sludge Blanket Level Meter utilises enhanced ultrasonic technology to measure the sludge interface level in various types of clarifiers, settling tanks and thickeners. The superior accuracy and reliability give continuous and real-time measurement. The numeric & graphic screens display the distance to the blanket, and give an echo profile image to ensure correct configuration during commissioning and saved data analysis. Additional features such as ASF (Abnormal Signal Filter) eliminate irregular field noise such as moving structures intermittently obscuring the signal. It also incorporates a compressed air cleaning system that keeps the sensor running optimally and guarantees maintenance-free measurement. Specially designed mounting kits are also available. Applications include Waste Water Treatment Plants, Sewerage Treatment and Industrial Water Treatment
