Measurement nodes as a part of GRS, AGRS, GRP

The equipment package which is a part of gas metering station is similar to an equipment package of metering station of GIS, except for in certain cases functions of duplication of measurement of component structure and physical and chemical indicators of gas, duplication of the channel of measurement of a gas rate, lack of functions of control of electrodrive cranes, a reserve automated workplace of the operator, the densitometer, the modular building of the block of measuring pipelines.

Are a part of a node of measurement:

• the block of measuring pipelines with converters of an expense and straight sections
• the gas quality control block the complex of hardware components of an automatic control system metering station which is carrying out the following functions:

1. automatic detection of a volume expense and amount of the natural gas given to standard conditions on each IT and on a node in general.
2. definition in the automatic mode of component composition of gas, gas density under standard conditions, volume combustion heat, Vobbe's number, dew point temperature on moisture and hydrocarbons.
3. forming and documentation of periodic reports.
4. automatic self-diagnostics of the equipment and automatic input of a reserve.
5. information transfer about amount of transported gas and operating modes of a node in master station (or industrial control system of the enterprise).
6. ensuring safe functioning of a node of measurement of an expense
