Natural gas flow metering system

Time of publication:2020-07-08 09:41


With the development of natural gas measurement technology, flow computer has been used to collect flowmeter and related parameters such as temperature, pressure, composition and density in natural gas metering and transmission station. Through corresponding conversion processing, the data is analyzed in accordance with GB / t18603-2014 "technical requirements for natural gas metering system", and the flow measurement data of natural gas is calculated Use this data as a trade settlement document. Chengdu Shidai huidao technology has the " Wisdom Eye" series flow calculation system developed by the company, which can receive the electrical signals of temperature, pressure and flow in real time, correct the temperature and pressure of the flow measurement value, and realize the accurate measurement of the flow.

Technical parameters:

It adopts 32-bit high-performance processor, wince embedded operating system, external touch screen, simple operation, convenient use and friendly interface.

According to GB / t21446, GB / t17747 and other national standards, natural gas flow rate, calorific value, compression factor and other data are calculated, and relevant algorithms of some international standards are also supported.

The flow computer screen can display the accumulated flow, instantaneous flow, pressure, differential pressure, temperature and other data of each set of flowmeter in real time.

It can query historical data, reports, event records, etc.

Calculation capacity: it can calculate 30 orifice flowmeter.

Slot: the host has 8 slots, which can be expanded if more than 8 slots.

It has system setting, parameter modification, data alarm, flow compensation, important operation and other event records.

The prompt box can be used to guide the operation, and the setting of the machine can be easily carried out through the man-machine interface, and the communication with the upper computer can be set through the upper computer.

Communication function: it supports Modbus RTU / TCP, user-defined communication protocol, RS232 / RS485 / Ethernet and other communication interfaces. It can form metering data acquisition and management system of various scales (from several points to thousands of points) according to needs, and can also be connected to SCADA system.
