Special equipment vortex flowmeter characteristics and its application

Project Overview

Special equipment vortex flowmeter is a volume flowmeter developed based on the Karman vortex principle to measure the volume flow rate of gas, steam or liquid, the volume flow rate under standard conditions or the mass flow rate. The special equipment manufacturing license, or TS certification, refers to the supervision and inspection by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on the production (including design, manufacturing, installation, modification, maintenance and other projects), use, inspection and testing of special equipment, and the assessment of the special equipment manufacturing license.

Qualified units will be granted business licenses and management actions to use the TS certification mark. At present, special equipment vortex flowmeters are mainly used for flow measurement of industrial pipeline media fluids, such as gas, liquid, steam and other media. The application inner diameter range of the vortex flow sensor is 25-300mm (full tube type). The application inner diameter range of the insertion vortex flow sensor is mm (insertion type). The full-tube type measures liquid with an accuracy of 1%, measures steam and gas with an accuracy of 1.5%, and the plug-in type measures liquid with an accuracy of 2%, measures steam and gas with an accuracy of 2.5%. The temperature of the measured medium is -20~150℃, -40~250℃, +100~350℃ (tube type only) output signal is three-wire voltage pulse, three-wire system 4-20mA, two-wire system 4-20mA.

The special equipment vortex flowmeter has a simple structure and is easy to install and maintain; it has high measurement accuracy, no moving parts, and high reliability; it has strong adaptability and various structural forms, and can measure a variety of fluid media, such as liquids, gases, and high temperatures. Steam, cryogenic liquid and partially miscible fluid; small pressure loss, can be used for a long time. Currently, there are few vortex flowmeter manufacturers with special equipment manufacturing licenses. Supmea Instruments can provide special equipment vortex flowmeters with TS certification.
