Vortex flowmeter for ambient carbon dioxide gas measurement

Project Overview

Background: The user's on-site pipe material is carbon steel, nominal diameter DN15; measuring medium carbon dioxide; temperature: normal temperature; operating pressure: 0.4MPa; the environment is non-flammable and explosive place; the available on-site power supply is 24VDC; measuring range 0-20m³ /h.

Carbon dioxide is an acid gas, so 304 stainless steel was chosen as the body material; in order to match the on-site pipelines, the matching flange was made of carbon steel; the flowmeter The rated pressure is 1.6MPa to meet the working requirements; there are no special requirements for signal output, and it is equipped with a standard 4-20mA current output signal; according to the tradition of measuring gases with vortex flowmeters, a temperature and pressure compensation device is recommended, which can provide more stable and accurate measurement Get the flow size. The accuracy range of this flow meter is 1.5%, which meets the on-site requirements.
