Introduction

The volumetric tube is a flow standard device for verifying the liquid flowmeter. This section covers the basic structure and technical performance requirements of the volumetric tube, Guide its design, installation and verification. This standard relates to the volume tube is a dynamic start and dynamic stop test equipment, the fluid in the quarantine period Continuous flow through the volume tube, the flowmeter can work in the normal test. This type of volumetric tube includes. replaceer, standard pipe section, Detection switch three parts. When the displacer enters the ball (or separation) zone with the fluid, the fluid flows through the bypass and the displacer stops run. According to the principle of this part, you can create a fixed or movable volume tube. The standard pipe section of the volumetric tube may be straight pipe or elbow (U-type), can be designed so that the displacer around a closed loop in one direction (one-way), can also be designed in two directions Line (two-way). Dynamic measurement of liquid hydrocarbons Volumetric metering system Part 2. volume tube

1 Scope

This part of GB/T 17286 gives technical guidelines for the design, installation and verification of volume tubes. This section does not include volume tube verification and A detailed calculation method for flowmeter verification. This section applies to different liquids, different types of flowmeters, and volume tubes that are tested using different methods. This part does not apply to small volume tubes.
