KROHNE has expanded its flow technologies for data centers with its OPTIFLUX electromagnetic and OPTISONIC ultrasonic flowmeters designed to maximize cooling availability, optimize system efficiency, and enhance reporting in modern data center environments.
The OPTIFLUX 2000 electromagnetic flowmeter delivers reliable, bi-directional flow measurement across a wide dynamic range making it well suited for chilled water and glycol-based cooling circuits commonly found in data centers. With chemically resistant polypropylene or hard rubber liners, no moving parts, and a full-bore design, it provides long service life without pressure loss, even in applications involving low-concentrated chemicals. With measurement accuracy to ±0.3% of measured value, combined with diagnostics for conductivity, electrode error, and process and ambient temperature, this device supports consistent performance in demanding cooling applications.
When conductivity is too low, KROHNE’s OPTISONIC inline and clamp-on ultrasonic flowmeters offer high accuracy, long-term stability, and insensitivity to magnetite, ensuring reliable measurement even where traditional technologies may drift over time. OPTISONIC clamp-on versions enable cost-effective, non-invasive installation on existing pipework, with no minimum conductivity requirement, making them ideal for retrofits or installations on non-conductive media in data center cooling systems. A wide turndown range and comprehensive diagnostics help operators maintain tight control over flow conditions, supporting efficient, resilient operation of critical cooling infrastructure.
A defining advantage of KROHNE’s data center flow portfolio is the integration of comprehensive diagnostics via OPTICHECK, including MID-MI-004 certified versions that support rigorous verification and compliance requirements in energy and cooling measurement. OPTICHECK enables on-site verification of OPTIFLUX, OPTISONIC, and other devices without process interruption, providing detailed diagnostic data and documentation to support asset management and quality assurance programs. With embedded and service-tool-based verification options, operators can regularly confirm meter performance, reduce the risk of undetected measurement drift, and support predictive maintenance strategies in mission-critical data center environments.
