Users Manual of this product.
The Sondar3000 sludge interface level meter consists of a microprocessor-based controller and transducers. This system measures and controls the solid/liquid interfaces in clarifiers, thickeners, settling tanks and other similar vessels. The Sondar3000 uses an ultrasonic measurement technique and is compensated for sound velocity due to variation in the temperature of the measured liquid/solid. The Sondar3000 measures not only sludge level but also the "rag layer" level that forms above the sludge. The Sondar3000 provides an automatic sensor cleaning unit that cleans off any scum deposited on the face of the sensor.
Features
- Sensor output power and measurement algorithm setting for various environments and media
- Graphic LCD display showing current output and percentage of set sludge level
- Auto sensor cleaning function
- RS-232 or RS485 is provided as an option
- Sondar3000-S single channel Sondar3000-D dual channel
