PURPOSE
( full specifications are in the manual for the device )
1. PC-V version 2 calculator is a measuring instrument and is intended for automatic converting the volume of gas measured by the meter connected to it under operating measurement conditions to standard conditions. One of the Calculator channels can be used to connect a gas meter in a non-explosive area with the following characteristics pulse signal:
– pulse duration – not less than 50 ms;
– frequency – no more than 10 Hz.,
– switched voltage – 12 V;
– short circuit current – less than 10 mA;
total number of meters connected to PC-V – 2 pcs.
At the same time, the meter connected to the Calculator PC-V version 2 does not require pressure and temperature correction measured by a household gas volume meter.
2. Calculator PC-V version 2 is intended for use as part of flow meters for metering, including for commercial accounting of gases in the gas, oil and gas producing, oil refining, petrochemical industries, industrial facilities and public utilities. and can be installed in explosive areas of open industrial sites and premises where the formation of explosive mixtures of categories IIA and IIB.
3. The PC-V version 2 calculator has an explosion protection marking II 2G Ex ib IIB T3 Gb and can be installed in explosive areas of open industrial sites and premises where the formation of explosive mixtures is possible categories IIA and IIB.
4. Operation of the PC-V Calculator version 2 is allowed at ambient temperature from minus 40 to plus 70 °С.
PS. – based on Calculators PC-V version 2 – measuring systems are supplied FLOUTEC-TM-2-3-4, FLOUTEC-TM-2-3-4-T, FLOUTEC-TM-2-3-6, FLOUTEC-TM-2-3-6-T.
The composition of the listed complexes is given at this link.
TECHNICAL DETAILS
1. The upper limits of pressure measurement by the calculator PC-V version 2 are set according to the order in the ranges:
