The flow module provides controlled air flow through the gas analyzer. Although optional, the flow module is recommended because it provides flow data that is recorded in the gas analyzer dataset.
The connector panel features an air outlet (EXHAUST), power cable connector, communications cable connector, and a ground lug. Early models (7200-101) have the intake on the bottom of the enclosure. Later models (7200-102) have the intake on top of the enclosure. Otherwise, the flow modules are the same.
Inside the case, you'll find a panel with indicator LEDs and controls. Although you can alter the flow settings and read diagnostics through the control panel, we recommend controlling flow through the software.
Note: When you start up the system for the first time, record the Pressure Drop and Motor Drive (%) readings to establish a baseline of normal, unobstructed readings.
