SS2-MVC300-0100 Azbil Corporation - 4 - SPECIFICATIONS Basic specifications Process fluid Steam only (saturated steam) Measurement range and accuracy [Flow rate] Measurable range See Table 1 through 4 on Page11. Accuracy Standard specification: ±3% rdg High-accuracy specification: ±2% rdg Range of guaranteed accuracy [Pressure (static pressure)] Measurable range 0.101 to 3.5 MPa abs* * This is output range of analog output * This is not an operating pressure limit. Accuracy Shown below * Since the absolute pressure sensor is used for the process pressure measurement, the gauge pressure is set as 0.101 MPa abs. [Temperature] Measurable range 0 to 300°C * * This is output range of analog output * This is not an operating temperature limit. Accuracy Accuracy is not specified because the temperature output is calculated from the steam table. Repeatability ±0.5% rdg of flow rate output Fluid pressure Rated pressure of a selected process connection Ambient temperature and steam temperature: Ambient humidity 10 to 90% RH (no condensation) Power source voltage 24 VDC (16.7 to 45 VDC) Pressure loss MVC30A: Ploss = MVC31A: Ploss = Ploss: Pressure loss when the flow rate is Q (kg/h or m3/h) Q: Flow rate (kg/h or m3/h) Qmax: Maximum flow rate in the range of guaranteed accuracy.
