SAGE PRIME™ THERMAL MASS FLOW METER FOR GASES

Sage Prime: Lowest energy usage of any Thermal Mass Flow Meter

Sage Prime™ is our most popular gas Thermal Mass Flow Meter preferred by our Industrial, Environmental and Commercial customers for a variety of applications. It is packaged in a robust, yet lightweight, dual-sided NEMA 4 enclosure with easy access to a separate rear compartment. Large, well marked terminals provide ease of customer wiring, providing full Modbus® compliant RS485 communications, isolated 4-20mA outputs, pulsed outputs of totalized flow, and the choice of 24VDC or 115VAC/230VAC operation (12 VDC Optional). The Prime can be incorporated into almost any Gas Flow application, is CE compliant, and meets UL, CSA and ATEX standards for hazardous service. It features a bright, high contrast graphical display (organic LEDs) reporting Flow Rate, Total and Temperature and even provides the raw calibration milliwatts (mw) for diagnostics which is the key to our popular, money saving, In-Situ Calibration Check.

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 display of Flow Rate, Total and Temperature in a robust, yet lightweight, dual-compartment industrial 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 24 VDC (12 VDC optional, or 115/230 VAC).The power dissipation is under 2.5 watts (e.g. under 100 ma at 24 VDC).

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 communications (IEEE 32 Bit Floating Point). Sage Prime is CE approved, and CSA, UL and ATEX approved for Hazardous Service⁽³⁾ (see Approvals tab on the website).

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" condition, and compare the reading to the original reported "zero flow" value noted on the last few lines of your meter's Certificate of Conformance 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 operating properly, verifies that there is no shift or drift, and eliminates the need for annual factory calibrations. This simple field diagnostic procedure, in addition, verifies that the sensor is free from contamination, even without inspection.

Although Sage Prime is fully configured upon shipment, for the pipe and process conditions requested, there are three strategies if changes are needed: Sage DONGLE; the Sage ADDRESSER software program; or the Sage ADDRESSER PLUS advanced program. Contact Sage for details.
