Overview
  • Precisely control flow rates with built-in valve
  • Proven design uses metal body components for added durability
  • Accumulated flow can be logged using an optional totalizer
  • Includes NIST-traceable certificate

These controllers 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.

The flow rate set point can be established by either a local potentiometer or by a remote 4 to 20 mA or 0 to 5 VDC signal. Output data is sent via a 0 to 5 VDC or 4 to 20 mA signal; an analog-to-RS converter is also available for data collection and analysis on your PC.

All controllers include a detachable 3-1/2-digit LCD that can be tilted up to 90° for easy reading. The display is remote mountable to three feet using extension cable 32662-70. The totalizer option 32650-22 will display total accumulated flow.

The controller 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.
