KVFN Intelligent Vortex Flow Meter, produced by Shanghai Kentand have gained CE certificate, can be widely used to measurevolumetric flow of overheated & saturated steam, compressed air& general gas, water and fluid etc.

TechnicalFeatures:

• Piezocrystal inbuilt in bluff body to avoid fluid turbulancecaused by external type, no zero drift and high reliability
• No moving parts, high durability
• Convenient installation and maintenance
• Sensor not connect with the measured fluids directly, stableperformance and long service life
• Output pulse signal is directly proportional to flowrate, highaccuracy and no zero drift
• Wide measuring range, turndown ratio 10:1
• Low pressure loss, low cost
• Frequency output not affected by the fluid change in physicalcharacter and composition, meter factor (K) only considers shapeand dimension of eddies. Measurement of volumetric flow can getcompensation once it needs. Then no re-calibration meter factorneeded if damaged parts be exchanged
• Wide application for steam, gas, liquid
