Figure 1.1 Typical System Configuration Using Flow Setting Units for Manual Calibration
1.1.2 System Configuration to Perform Automatic Calibration
A typical system configuration to perform automatic calibration is illustrated in Figure 1.2. The system
consists of detectors, an averaging converter, solenoid valves, needle valves for flow control, and a
float-type flowmeter.
