Air/N2 Gas Mass Flowmeters with Metal Bodies

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 U-shaped 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. 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.

Accuracy:
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.

Environmentally Preferable:
