The Ultrasonic Measuring Instruments, Density, Level and Flow

In recent years, wastewater treatment plant operators’ efforts have increasingly been aimed at devising economically efficient processes in wastewater and sludge treatment besides actually eliminating pollutants. Use of modern instrumentation and control systems in various stages of the wastewater treatment plant processes supports, or rather permits in many cases, controlled wastewater and sludge treatment. By using WESS’s sludge blanket level meter & suspended solid density meter great cost savings can be achieved over the year Automates the discharge of waste activated sludge based on the sludge blanket level Waste activated sludge draw-off is controlled by continuous measurement of the sludge level using a minimum/maximum contact for the sludge level.   Increase the hydraulic capacity of a thickener and the gas yield in a digester, decreases heating energy used in a digester Sludge which is too thin causes increased costs in heating digestion tanks, in the sludge dewa...

ENV200 basically utilizes ultrasonic signal attenuation principle. 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 temperature in the process. The ENV200 use the EEA(Envelope Energy Average) method that saves reception signal and then calculates its energy, rather than using the reception signal’s amplitude change.
