PRIME™ DATA SHEET
PRIME™ THERMAL MASS FLOW METER FOR GASES
The Prime is the top selling meter in our Product line.The 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 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). The Prime is CE approved, and CSA, UL and ATEX approved for Hazardous Service(3).
CONTINUOUS DIAGNOSTICS & FIELD CONFIGURABILITY
The 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 the Prime is fully configured upon shipment, for the pipe and process conditions requested, there are three strategies if changes are needed: The DONGLE; the ADDRESSER software program; or the ADDRESSER PLUS advanced program. Contact NOVO Environmental for details.
MAJOR BENEFITS OF THERMAL MASS FLOW METERS
