What really matters when 

measuring gas mass flow?

Performance - Repeatability - Reproducibility


Do you want Accuracy with Award-winning and Innovative Products?

We have been specifying thermal mass flowmeters for 18+ years and Sage Metering gives you innovative, high-performance gas flowmeters for gas mass flow measurement.  Sage was originator of the first thermal mass flow meter to utilize graphical displays, a hybrid digitally driven circuit and pioneered the industry’s first in-situ calibration verification system.  The high contrast graphical display provides you flow rate, temperature, total flow, a bar graph, and diagnostic information. The digitally-driven circuit eliminates the traditional drift-prone analog Wheatstone bridge, improving your stability, elminating long term drift and provides a reproducble zero flow data point.  This enables you to perform a simple single-point in-situ calibration verfication traceable back to the original NIST calibration certificate.  You can perform this check while the process is running with the SageCom™ software, downloading the results into a PDF format.

How you benefit by using the Sage Paramount Flow Meter:

  • Measures direct mass flow rate/total without needing additional pressure and temperature instruments

  • Insertion probes (for 1.5" - 36" pipes) with optional retractor allows you easy removal and isolation

  • Digital Sensor Drive ensures you measurement stability over time

  • SageCom™ software for expanded gas selection menu allows you to choose from available list of gases/gas mixes to measure flow. and perform NIST-traceable calibration, Bluetooth now available

  • Calibration milliwatts is continuously displayed, providing you ongoing diagnostics

  • Standard 4-20 mA, pulse & Modbus RS-485 outputs, w/optional HART protocol gives you plenty of communication choices

  • Field Zero Calibration Check gives you confidence meter hasn't drifted (download via SageCom™ software) for reporting

  • 24 VDC in local or remote enclosures with optional 120 VAC
