K-BULK
ULTRASONIC FLOW METER
Images for demonstration purposes only: elements may vary
K-BULK is the ultrasonic flow sensor designed for precise thermal energy measurement in centralized heating and cooling systems. The measuring element, with no moving parts, ensures long-term reliability even under harsh operating conditions. The metallic body with IP68 protection includes battery-powered electronic (10+1 years lifetime), making the device suitable for humid or demanding environments. Thanks to the dual ultrasonic paths and compatibility with Maddalena KS3C calculators and KPTEG probes, K-BULK guarantees maximum accuracy and interoperability in direct metering systems.
