ENV-100 |
Description
WESS ENV-100 sludge blanket level meter utilizes its specialized ultrasonic technology to measure sludge interface level in various types of clarifiers, settling tanks, and thickeners. The ENV-100 offers useful information with numeric & graphic screens, such as range of blanket level, echo profile image, and logged data analysis etc. By adopting VTA(Visual Threshold Voltage) and ASF(Abnormal Signal Filter) functions, user can overcome the harsh field condition. Its built-in probe cleaning nozzle makes automatic probe cleaning efficiently with no additional cost and the swing bracket helps to protect the probe from skimmer travels
