Thermal Mass Flowmeters/Controllers


The Compact Series of flowmeters and controllers are the ideal alternative to traditional Variable Area (VA) flowmeters (Rotameters). Practically unaffected be Temperature and Pressure variations, they offer a wide range of sizes with high accuracy and extended flow turn-down.

The Compact Series is available in battery powered (ca. 2 year duration) and 24 Vdc versions. With optional Totalizer and Alarm functions and optional manual control valve, this flowmeter is well suited for TrigasFI's low cost manual gas mixing systems and similar applications.
