Masterflex® Compact Gas Mass Flow Sensors/Transmitters, Avantor®
Accurate and corrosion resistant.
- Nonclogging straight sensor tube provides high accuracy
- All models include a calibration certificate to NIST-traceable standards
Flow transmitters combine a restrictor flow element with an advanced straight sensor tube to provide high accuracy and repeatability. Gas flow rates are unaffected by temperature and pressure variants within limitations.
Select from aluminum or 316 stainless steel (SS) models. Wetted materials are anodized aluminum, brass, and Viton® for aluminum models; SS and Viton for SS models.
These precalibrated flow transmitters 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 percentage of 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.
