ATEX Zone 1 Approved
Aysix RIO THERMAL MASS FLOWMETER FOR GASES
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. It is powered by 24VDC (115/230VAC optional). The power dissipation is under 2.5 watts (e.g.under 100 mA at 24VDC). Standard outputs include 4–20mA, pulsed outputs of totalized flow and full Modbus compliant RS485 RTU communications or optional HART communication.
Aysix Rio is Zone 1 approved: II 2G Ex d IIB+H2 T6 Gb. T6 Rating issuitable for gases with ignition temperature as low as 185°F (85°C).
Aysix Rio 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) condition, and compare the reading to the original reported “No 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 Aysix Rio is fully configured upon shipment for the pipe and process conditions requested, if changes are needed, Addresser software is optionally available.
