- Model ENV200 Series - Ultrasonic Sludge Density Meter



The ENV200 is an ultrasonic instrument that measures the density of suspended solid in liquid. It comprises of sensors, a controller, and a junction box. ENV200 with PCM(Process Condition Monitoring) algorithm measures not only the size of received signal, which is often measured by conventional ultrasonic density meters but also observes changes in sound velocity and temperatures in the process. As it monitors operational status and water status in pipe and then decides the validity of each measurement, it contributes to increasing stability and reliability of the measurement. The ENV200 utilizes the EEA (Envelope Energy Average) method that saves reception signal envelop and then calculates its energy, rather than using the reception signal’s amplitude change. ENV200 offers three types of sensors, such as spool-piece, tank-mount, and Clamp-on type to accommodate all field demands at installation.
