Explanation/Annotation:For determination and commercial record of expenditure and volume of hot and coldly
water é in systems of heat and water supply and other fluids.
is included in State register of measuring means of Russian Federation .
Detailed model description:Information, displayed on LC display: flow rate, (Cuba. m hour);
parcel of liquid, passed through pipe-line, progressive total
(Cuba. m); working time in ðåëüíûõ hours (year, day, hour, minute).
hourly average and the average daily parameters, which remain deposited in the archives and
LC display, the stamp, the PC are put on: parcel of liquid, passed
through pipe-line, (cu. m.. ; calendar data, demanded
parameters and working time of ðàñõîäîìåðà-ñ÷åò÷èêà.
delivery set: primary sensor of expenditure for MM ÄÓ=15-200
or 2 piezoradiators with set of montage parts for encastre in
pipe-line for yes more 200 MM; calculator, state. 1; cables set
for connecting of piezoconverters.

time, % + (-) 0. 1 + (-) 0. 1
a side benefits: can be completed general-purpose
printer cable (under order), which allows to use other
printers; have the programme version, for providing of them
capacity to work in local network to 32 customers. |
