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℃.
