There are several industries where sludge levels or solids in liquids need to be detected. For example, in sediment tanks or basins, filters or lamella separators in the metal industry, in chemical plants, in lime or gravel works and in the wastewater industry. What matters here is the measurement accuracy and also durability of the sensor technology. Pollution, chemicals and gases often have a negative affect on the sensors and require special resistance.
Continuous level measurement:
The plumb bob series NivoBob® NB 3300/3400 meets the requirements of many interface measurements and are very reliable due to the simple measuring principle. A 4-20mA analog signal as well as a Modbus RTU/Profibus DP interface are available for level evaluation.
Level limit measurement:
Vibration forks of the Vibranivo® series VN 1000 or VN 5000 can be used to measure limit levels of slurries and solids in liquids. The wetted parts are made of resistant stainless steel. With the VN 1030 and VN 5030 versions, even depths of approx. 4m can be realized when installed from above in a tank or basin. The high sensitivity required for the respective solids detection can be easily set on the electronics.
