Turbine / Ultrasonic Metering System
Turbine / ultrasonic metering system is a skid-mounted metering system for custody transfer metering in the metering station of long distance gas pipeline.
Application
The system integrates the functions of filtering (or the filtering part is separated), metering, flow ratios, on-line calibration, system venting, leak alarm and automatic switching, having the characteristics of high metering accuracy, good safety performance, continuous stable metering and high explosion proof requirement.
In a typical pipeline station the sequence is: Station inlet → Filtration → Regulation → Metering → Station outlet.
Scope of supply
- Characteristics 3D This system is composed of some subsystems, such as filtering system, metering system, flow ratios system, gas chromatograph analysis system, on-line calibration system, venting system, gas leak alarm system and etc.
- The accuracy of the filtering system is much more strict comparing to in other situations,besides gas turbine flowmeter or gas ultrasonic flowmeter, straight pipe meeting the requirement and suitable flow computer for temperature and pressure compensation calculation are used in the metering system.
- On-line type gas chromatograph detects the gas components.
- Two or more flowmeters series to achieve intercomparison,what is flow ratios.
- According to processing requirement,on-line calibration system reserves on-line calibration port in the system.
Capacity, design conditions and scope of supply are confirmed per project.
