The Liquistation CSF48 automatic water sampler complies with worldwide water regulation, features a fail-safe cooling system and vandalism-proof housing guaranteeing outstanding safety for your samples. Easy, menu-guided sample programming and tool-free maintenance save you time in your everyday tasks. Liquistation can be upgraded to a complete measuring station for modern environmental monitoring at any time giving you the flexibility to address future demands.
Liquistation CSF48 is suitable for the following applications:
Municipal and industrial wastewater treatment plants:
- Self monitoring
- Process monitoring
- Monitoring of indirect dischargers
- Monitoring of sewage systemAuthorities and water management authorities:
- Water protection and water quality
- Monitoring of direct and indirect dischargers
Benefits
Automatic water sampling in full compliance with all relevant national and international standards such as ISO 5667
100% adaptable to any monitoring task from time- or flow-controlled sampling to event-controlled sampling
By connecting up to four Memosens sensors, the sampler can be upgraded to a fully-fledged measuring station (e.g. for event monitoring)
Offers all the benefits of the Liquiline platform, such as uniform operation of all devices, easy expandability and reduced need for spare part stock thanks to standardized components
Fully integrable in any process control system thanks to digital fieldbus communication and remote access via web server
Quick cleaning and maintenance thanks to easy, tool-free removal of wetted parts
Heartbeat Technology enables status-oriented maintenance of the device, saving resources and costs
