The Endress+Hauser Liquiline System CAT180 is a self-cleaning backflush filter for sampling from pressurized pipes and outlets. The Liquiline System CAT810 provides filtrate for continuous online monitoring of municipal and industrial wastewater and industrial processes. Its self-cleaning crossflow filter avoids filter blocking, thus increasing your process safety. Thanks to a minimized dead volume, it reflects changes in your process promptly and shortens the response time of your downstream measuring devices.
