Accessories
CSA Class I, Division 2 certified radios and modems can be included in the Scanner 1141 enclosure.
Since these devices are rated up to +60°C (+140°F), the Scanner 1141 operating temperature must be
reduced to +50°C (+122°F).
Lightning arrestors are also available for radio antenna connections. Since these devices are rated up to
+50°C (+122°F), the Scanner 1141 operating temperature must be reduced to +40°C (+104°F).
Currently, remote communication devices and lightning arrestors require CSA special acceptance.
Firmware
The Scanner 1141 supports version 4.3.5 and higher of the standard Scanner 1100 Series firmware for
turbine and orifice measurements. Two or three flow runs can be configured in the Scanner 1141, within
the limits of memory (256 Kbytes of RAM/NVRAM) to perform the following calculations:
•
AGA-3 calculations for orifice metering using MVT, MVX-II, analog and RTD inputs
•
AGA-7 calculations from a linear flow meter, such as a turbine meter
•
flow through a liquid stream based on pulse or analog inputs
•
monitor runs to measure pulse input totals or analog inputs
