Master Flex Flow Meter 32654-12 Aalborg Thermal Gas Mass, Aluminum Body with Display to 1L/min H2 1pc

Precisely measure flow rates and totals.









Proven design uses metal body components for added durability
Accumulated flow can be logged using an optional totalizer
Includes NIST-traceable certificate





These flowmeters feature an advanced straight-tube sensor that ensures accurate and repeatable results. Gas flow measurements are unaffected by moderate temperature and pressure variations at the inlet. The meter also allows a four-point calibration across the flow range to improve meter linearity. Output data from the meter can be sent via a 0 to 5 VDC or 4 to 20 mA signal; an analog to-RS converter is available for data collection and analysis on your PC.

All meters include a detachable 3 1/2-digit LCD that can be tilted up to 90° for easy reading. Remotely mount the display up to three feet using extension cable 32662-70, cable sold separately. The optional totalizer 32650-22 displays accumulated flow. The meter is protected from polarity reversal or short circuit by a built-in resettable fuse. Aluminum models have wetted materials of anodized aluminum, brass, and Viton; stainless steel (SS) models have wetted materials of SS and Viton.

These precalibrated flow controllers operate at inlet pressures between 5 and 60 psi and at gas temperatures between 59 and 77 °F (15 to 25 °C) while maintaining the stated percent full-scale accuracy and linearity. When operating beyond 5 to 60 psi, add ±0.01%/psi full-scale; if operating beyond 59 to 77 °F (15 to 25 °C), add ±0.15%/ °C full-scale.

Power supply allows flowmeters to be powered by AC voltage. Order 110 VAC power supply 03277-00, or 220 VAC power supply 03277-05. Power supplies are sold separately.
