Insights

Product & Semiconductor Flow Expert

New compact clamp-on ultrasonic meter targets contamination-sensitive semiconductor fluid loops with claimed high accuracy and easy integration.

Malema launches the M-3100 Series, a clamp-on ultrasonic transit-time meter for liquid-filled closed conduits aimed at semiconductor use on Oct. 14, 2025. The design prioritizes non-contact sensing to reduce contamination risk and offers stated accuracy of ±2% and repeatability of ±1%. Physical sizes include 1/4", 3/8" and 1/2" models and a DIN rail mount for tight spaces.

The business mechanism is straightforward: a non-invasive sensor reduces process interruption and contamination risk while enabling flow measurement without pipe penetration. Integration options include analog outputs and RS-485 Modbus, plus a GUI for parameter tuning, which eases deployment into existing control systems.

Key dependencies and risks include actual field performance versus the stated ±2% accuracy, installation variability on clamp-on devices, and adoption by semiconductor tool and fab engineers who require proven contamination controls. The announcement provides no independent test data or customer deployments, so measured validation is needed.

Concrete items to watch are documented third-party validation or published install case studies, availability and lead times, and any firmware or software release notes that define supported Modbus registers; expect early validation evidence within the next 3–12 months.
