Ultrasonic Sludge Density Meter – Overview The ENV200 is an ultrasonic instrument that measures the density of suspended solids in a liquid. It consists of sensors, a controller, and a junction box. The ENV200 with the PCM (Process Condition Monitoring) algorithm measures not only the size of the received signal but also observes changes in sound velocity and temperatures in the process. As it monitors the operational status and the water status in the pipe it then decides the validity of each measurement, contributing to increased stability and reliability of the measurement. The ENV-200 utilises the EEA (Envelope Energy Average) method that saves the reception signal envelope and then calculates its energy, rather than using the reception signal’s amplitude change. It offers three types of sensors, such as spool-piece, tank-mount, and clamp-on type to accommodate all field demands at installation. Ultrasonic Sludge Density Meter – Features Continuous measurement Process monitoring possible (run, stop, full, empty) 10,000 points data logging EEAM (Envelope Energy Average Method) Various types of sensors Does not require bypass pipeline or special tools to install Clamp-On Ultrasonic Sludge Density Meter – Features Continuous Measurement Low Maintenance No sensor cleaning required for sludge adhesion No wear and tear from flowing medium No special tools required for installation Can be used in a small space No Additional Cost No additional water pipeline needed for sensor cleaning No by-pass line needed for maintenance No Limit on Measuring ASF (Automatic Signal Filter) Can be used for almost any type of sludge
