Model SLUDGE SAMPler - Special Automatic Water Samplers
SLUDGE SAMPler is designed for sludge sampling from pressure pipelines (up to 6 bar). Sample taking, including blowing of the supply pipe, is done by compressed air. (Air compressor is not included). Sample taking begins with pressurizing the sampling system to higher pressure than the pipeline and the detection of any leakage. The supply valve is then opened and the overpressure in the system cleans the supply pipeline. The sediment flow into the sampling chamber is controlled by expansion receptacle. Once the pressures in the system have been balanced, the compressor pressure pushes the excess sample volume back to the pipeline and the supply valve is closed. In the final stage, the sample is drained into the sampling container. Samples can be taken in regular time intervals or upon impulses from flowmeter after a defined amount of sediment has flown through.
