A sample pump (side or immersed type) provides a continuous stream of sample at 8 m3/h through one filter tube while the other tube is in stand-by. The filter tubes operate under virtually zero pressure conditions. The filtrate pump has two functions: It determines the filtrate volume and supplies the Monitor with the necessary sample pressure.
