Pipeline-type Flanged Installation Vortex Flow Meter Gas Flow Meter
Introduction
Vortex flowmeter is a flow meter operating with Karman Vortex Street principle for flow rate of gases (air, oxygen, nitrogen, coal gas, natural gas, chemical gas, etc.). It could be used in automatic control system as flow transmitter. The product adopted advanced differential technique, together with measurement of isolating, shielding and filtering, it had possesses better anti-vibration performance and signal stability.
Features
1. Flange body: integrally forged pieces, it will avoid break down into pieces.100% SS304 material,we can provide material report.
2. Circuit Board: Digital circuit board,anti most of the supplier use analog circuit board,digital circuit board enjoy the advantages of anti-vibration and anti-interference.
3. Flow converter: Distinctive modular design, amateurs can operate, disassemble and assemble easily, it will avoid accident risks.
4. Welding: adopt the advanced fish scale technology,which makes the welding seam looks nice and smooth.
5. Japan OVAL technology with embedded-type sensor, triangular prism will not fall off, we already apply for patent.
6. Our medium temperature sensor can measure highest temperature around 350℃,normal it is -40~250℃.
