SAGE PRIME™ THERMAL MASS FLOW METER FOR GASES
Sage Prime is the top selling meter in our Product Line. The Sage Prime Thermal Mass Flow Meter features a bright, high contrast, photo-emissive OLED (Organic LED) display of Flow Rate, Total and Temperature in a robust, yet lightweight, dual-sided NEMA 4 enclosure. The Flow Rate is also displayed graphically in a horizontal bar graph format. The rear compartment is completely separated from the electronics, and has large, easy-to-access, well marked terminals, for ease of customer wiring (see photo below). It is powered by 24VDC (12VDC optional, or 115/230VAC). The power dissipation is under 2.5 watts (e.g. under 100 mA at 24VDC).
The Sage Prime Flow Meter is offered in Integral or Remote style (which has lead-length compensation up to 1000 feet as well as an Explosion Proof Junction Box). Specify any standard probe length or ﬂow body size. It has a 4-20 mA output as well as a pulsed output of Totalized Flow (solid state transistor drive). In addition, Sage Prime supports full Modbus® compliant RS485 RTU communi cations (IEEE 32 Bit Floating Point).
Sage Prime is CE approved, and CSA, UL approved for Hazardous Service1 (see “Approvals”under the “Knowledge Base” tab on the website). For ATEX Zone I approvals, request Sage Rio Flyer (SIX Series).
CONTINUOUS DIAGNOSTICS & FIELD CONFIGURABILITY
Sage Prime has continuous diagnostics. The raw calibration milliwatts (mw) is always displayed in the upper left hand corner of the meter’s display. At any time, you can check this reading at a “No Flow” (0 SCFM) con dition, and compare the reading to the original re ported “No Flow” value noted on the last few lines of your meter’s Certi ﬁcate of Con formance or the Flow Meter’s data tag. This in-situ diagnostic procedure not only checks the sensor performance and the “Live Zero” calibration point, but it also veriﬁes that the sensor is clean. It essentially provides a means to validate that the meter is oper ating properly, veriﬁes that there is no shift or drift, and eliminates the need for annual fac tory calibrations. This simple ﬁeld diag nostic procedure, in addition, veriﬁes that the sensor is free from contami nation, even without inspection. Although Sage Prime is fully conﬁgured upon shipment for the pipe and process cond itions requested, if changes are needed, SageCom™ software is optionally available for ﬁeld reconﬁgurability and performance validation and a printed report.
MAJOR BENEFITS OF THERMAL MASS FLOW METERS
- Direct Mass Flow – No need for separate temperature or pressure transmitters
- High Accuracy and Repeatability – Precision measurement and extraordinary repeatability
- Turndown of 100 to 1 and resolution as much as 1000 to 1
- Low-End Sensitivity – Measures as low as 5 SFPM (e.g., 1 SCFM in a 6″ pipe)
- Negligible Pressure Drop – Will not impede the ﬂow or waste energy
- No Moving Parts – Eliminates costly bearing replacements, and prevents undetected accuracy shifts
- Dirt Insensitive – Provides sustained performance
- Ease of installation and convenient mounting hardware
