Gas flow metering units and skids (GFMU and GFMS)

Application

Gas flow metering units and skids (GFMU and GFMS) are designed or technological and commercial metering of natural gas corrected to standard conditions by means of automatic electronic adjustment of temperature and pressure readings.
GFMU is designed for a required pressure; it is used in the structure of GMS, AGDS and for other process needs.

GFMU configuration

GFMU can consist of the following lines and their possible configurations as per a technical specification:

• basic gas pipelines with a bypass;
• basic gas pipelines with 100% reservation;
• basic gas pipelines with 100% reservation and the line of small gas flow;
• configuration with Z-shaped diagram, etc.

On the basis of measuring method we can offer several GFMU modifications with application of different components:

• orifice plates;
• turbine meters;
• rotational meters;
• ultrasonic meters;
• vortex meters.

Measurement error of GFMU is up to ±1.5% according to the requirements to the standard of commercial gas flow.

For commercial gas flow metering natural gas is reduced to standard conditions by a flow computer selected by the customer; it can be Floboss 107, SuperFlow, HyperFlow, etc. Absolute and differential pressures and gas temperature are measured by sensors produced by certified companies. If it is necessary to measure gas parameters, GFMU is equipped with chromatographs and calorimeters.

Functions

GFMU has the following functions:

• momentary gas flow measurement and indication under working and standard conditions;
• accumulation and storage of average hourly and average daily parameters and gas volume in archives within 30 days and a possibility to output this data to the display and external devices;
• gas parameters recording;
• identification of abnormal situations during operation of the unit and gas measurement in accordance with the specified algorithms and contractual values within the period of this abnormal situation.

Types of structure

• in the frame,
• in the frame and under the roof,
• in the unit, etc.

Depending on the temperature conditions absolute and differential pressure sensors can be located in a heat-insulated heated cabinet.

According to design assignment BatysMunaiGazZhabdyktary, LLP can produce gas flow metering units and skids (GFMU, GFMS) of any configuration and capacity.

To select the measuring instruments and design a construction taking into account all the requirements, we ask you to fill in the questionnaire presented on our website. In order to take into account all customers’ requirements would you be kind to fill in a questionnaire at our website.
