This flowmeter provides the functions and performance required to monitor and manage factory air consumption. Its development was based on the following points derived from discussions with customers about monitoring and managing factory air consumption.
Mass flow rate measurement
Integration of all functions needed for monitoring and managing air consumption
Low cost
This device is equipped with a constriction mechanism whose measurement principle is the same as that of orifice, nozzle, and Venturi tube differential pressure flowmeters. The constriction mechanism employs an elliptical throat that was developed by Azbil Corporation and has a proven track record. Among its strong points is high-accuracy measurement in short straight pipes. For the converter, we use a multivariable sensor that detects differential pressure, pressure, and temperature with high accuracy. The converter applies density correction to the process variable detected by the multivariable sensor to give an accurate mass flow rate.
Auto ranging function
In differential pressure type flowmeters, the instantaneous flow rate range needs to be set by calculating the differential pressure generated from fluid conditions including flow rate value. However, the flow rate value of factory air is not known in most cases. The flow meter for air monitoring and management is equipped with auto ranging function that memorizes the maximum flow rate value of the actual flow rate even when the flow rate value is unknown and automatically sets the range.
Wide flow rate range
The flowmeter for air monitoring and management can handle a range up to 100:1 so is an ideal for covering a wide flow rate range. This eliminates worries about a large or small flow rate when selecting a flowmeter whose bore or diameter is the same as that of the factory air pipe.
Enhanced display function
The LCD display on the front face can selectively display the instantaneous flow rate value, total flow rate value, and flow velocity value. The multivariable sensor's pressure value for calculating the compensation can also be shown on the display making it usable as a pressure gauge monitor.
