KVFN Интеллектуальный вихревой расходомер

KVFN Intelligent Vortex Flow Meter, produced by Shanghai Kent and have gained CE certificate,can be widely used to measure volumetric flow of overheated & saturated steam, compressed air & general gas, water and fluid etc. Technical Features: Piezocrystal inbuilt in bluff body to avoid fluid turbulance caused by external type, no zero drift and high reliabilityNo moving parts, high durabilityConvenient installation and maintenance Sensor not connect with the measured fluids directly, stable performance and long service life Output pulse signal is directly proportional to flowrate, high accuracy 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 physical character and composition, meter factor (K) only considers shape and dimension of eddies. Measurement of volumetric flow can get compensation once it needs. Then no re-calibration meter factor needed if damaged parts be exchanged Wide application for steam, gas, liquid Technical Specifications: Size: DN15 DN300 Medium: Liquid / Steam / Gas Accuracy: Pipe Type: ±1.5% (gas, steam), ±1.0% (liquid); Inserted Type: ±2.5% (liquid),±3.0% (gas)Repeatability: Pipe Type: 0.5% (gas, steam), 0.33% (liquid); Inserted Type: 0.83% (liquid), 1.00% (gas)Rated Pressure: GB 1.6MPa, 2.5MPa, 4.0MPa, 6.4MPa; DIN PN16, PN25, PN40; JIS 10K, 20K, 40K; ANSI Class150, Class300, Class600Signal Output: Pulse Output, Two Wire 4 20mADC, RS-485, Hart, ModbusPower Supply: 24VDC / 3.6VLithium Battery / Double Power Supply (24VDC, 3.6V Lithium Battery) Installation type: Flanged Type / Wafer Type / Fixed Inserted / Adjustable Inserted /Adjustable Inserted (withballvalve)Protection Grade: IP65Explosion Proof: Exd IIBT3 6/ Exia IIC T3 6Fluid temperature: -40 +250oC (-40 +120oC for insterted), +100 +350oC (high temperature)
