1、 Product Overview

Ultrasonic sludge concentration meter is an online monitoring instrument designed for measuring the concentration of high concentration sludge and slurry in municipal sewage, industrial wastewater, industrial slurry and other treatment processes. Real time online monitoring of changes in sludge and suspended solids concentration ranging from 0.2% to 60% and automatic control of related process can be achieved. Ultrasonic measurement method is safer than X-ray measurement method and is therefore widely used in the field of water treatment.

Scope of Application

Water treatment plants, sewage treatment plants: return sludge, primary sedimentation tank, secondary sedimentation tank, concentration tank, sludge dewatering, etc

Washing mine: detection and control of particle impurity concentration such as slurry concentration, coal slurry concentration, mortar concentration, pulp concentration, etc
