Oxygen (O2) 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 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 analogto-
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.
