Benefits

Early online detection of critical silica levels ensures efficient power plant performance and optimizes maintenance and blowdown cycles by early counter measures.
Standard heteropoly blue method allows direct comparability to lab results.
Best reliability: Unique combination of peristaltic and high-precisions dispenser pumps ensures stable operation and low maintenance.
Optimized investment: The option of up to 6 sample channels meets changing process needs at any time, and connection of Memosens sensors allows an easy upgrade to a complete measuring station.
Seamless integration into process control systems thanks to digital field buses such as Modbus, EtherNet/IP or PROFIBUS.
Advanced diagnostics and remote access via web server enable fast remedy in case of errors.
Drive connectivity: Liquiline Edge Module CYY7 transfers process data to Netilion, independently of the fieldbus. This allows remote overview and the use of IIoT services. It’s available in new products or as upgrade to installed Liquiline platforms.
