- 1 - 4th edition No. SS2-MVC200-0100 OVERVIEW The Multivariable Mass Flow Meter AIRcube, a compact flow meter has all function necessary to measure nitrogen (N2) gas, carbon dioxcide (CO2 ) gas and air. The model MVC10A/MVC10F can accurately measure differential pressure, static pressure, and process temperature to dynamically calculate fully compensated mass flow of factory compressed air, and N2 gas in food and beverage for anti-oxidation. The model MVC10A/MVC10F is very useful to save energy with indicating cost of air, N2, CO2 and leak-check function. FEATURES High accuracy A state-of-the-art Dual Sensor realizes accurate measurement of mass flow rate by measuring Differential Pressure (DP), Gauge Pressure (GP), and Temperature (T) for the density compensation. Full display function Model MVC10A/MVC10F can display volume flow and mass flow, and velocity or pressure. Stable measurement . The streamline shaped flow tube (etube) can minimize the scaling and the clogging. . Output is with excellent reproducibility due to smooth and stable streamline by elliptic tube. The rangeability of flow rate is as wide as 1 to 30, so measurement is possible down to almost zero flow rate. . Even with a short upstream length, it provides high accuracy. Unique functions . Cost indication To save energy management, it has cost indication. . Auto ranging function The measuring range can automatically set with memorizing maximum flow even if the actual flow rate is unknown. . Leak check function Measuring pressure in pipe with built-in pressure sensor, indicate leak rate necessary to economize energy. APPLICATIONS . Measuring air flow each manufacturing process . Promoting economized energy to grasp actual consumption of air each factory and shop . Observing capacity of equipment . Measuring flow of N2 & CO2 gas PRINCIPLE The AIRcube is a differential pressure flow meter based on the Bernoulli theorem. Flow (Q) is calculated by the following equation. ΔP : Actual differential pressure ρ : Density of gas P1 : Primary pressure T1 : Temperature A : Flow coefficient .. = ..
