Ultrasonic Sludge Depth Meter
K-DM
Key Features
- Equipped with a microprocessor for stable and continuous statistical signal measurement
- Measures the depth without disturbance
- Excellent tracking of depth level changes
- No moving parts, hence maintenance is very easy
- Current value can be verified
- Displays the sludge depth on a color screen

Main Functions
- Enhanced display function with a large LCD
-LEVEL, TEMP, TREND, GRAPH (Ultrasonic ECHO waveform) - Simple parameter setting function
- Adjustable LCD brightness
- Possible to connect two sensors to one converter
- Built-in TREND function allows for monitoring past 5 minutes to 48 hours of LEVEL changes on the LCD
- Data logging (micro SD card) feature
