Flange Clamp Connecation Vortex Flow Meter Gas Flow Meter For Compressed Air From Air compressor
Introduction
Karman vortex flowmeter, which is widely used in industry, is a kind of flowmeter made by using the phenomenon of Carmen vortex. When the vortex generator is vertically inserted into the fluid, Karman vortex street will be formed when the fluid bypades the generator. Under certain conditions, the asymmetric vortex train can remain stable. In this case, the frequency f of the vortex is directly proportional to v of the flow rate of the fluid, and inversely proportional to d of the front width of the vortex generator.
KVF flowmeter is a Karman vortex flowmeter using the principle of Carmen vortex flowmeter, can be used for air, oxygen, gas, natural gas, and other chemical gas measurement. The product adopted advanced differential technique, together with measurement of isolating, shielding and filtering, it had possesses better anti-vibration performance and signal stability.It is characterized by small pressure loss, large range, high precision, almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow in working conditions. No moving mechanical parts, so high reliability, small maintenance. Instrument parameters can be stable for a long time.
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℃.
