Azbil MVF1003CAN0110000 Micro Flow Vortex Gas Flowmeter incorporates a µF (Micro Flow) sensor made by silicon micro-machining and thin film technologies. Because a high-sensitivity, quick response sensor that is a mere 1.7 mm square and 0.5 mm thick is used for the detection of the vortex frequency, a wide measurement range of 100:1 has been achieved. Since this flowmeter covers such a wide measurement range in the service flow range, they can be used for popes with unknown rate, without worrying about selecting a suitable model. Since Temperature and pressure compensation functions are integrated, there is no need to use temperature and pressure sensors and compensation devices, thus reducing the cost of ownership. Comprehensive interfaces such as 4 to 20 mA instantaneous flow rate output, pulse output for totalization communications functions (RS-485 communication), etc. are integrated as standard functions. Therefore this device can be used in combination with a wide variety of external devices. The instantaneous flow rate / total flow display enables easy confirmation of these values at the work site. IP67 structure for outdoor applications. Volumetric flow rate accuracy (air, at 23 °C and at 0.01 MPa): ± 2% rdg at 154 m3/h (actual) or more ± 2% RD*. Accuracy after temperature and pressure compensation: At 0.5 MPa ± 3.3% rdg at 156 m3/h (normal) or more ± 3.3 RD**, CE marked.
*Differs according to operating pressure and flow rate
**The above accuracy after temperature and pressure compensation with a pressure sensor having a span of 0 to 1 MPa
