3.1

Flow Rate Verification and Adjustment

Once the pressure verification is complete (see Chapter 2), the gas flow rate should be verified. Accurate
gas flow through the nozzle is critical for achieving repeatable results. The DRS25 incorporates a Mass
Flow Controller with closed loop control to monitor and regulate gas flow rates.

The two areas of flow verification include the Nozzle Flow Controller, which controls actual flow rates and
the Nozzle Flow Sensor, which controls the Computer Digital Flow Display. Nozzle flow verification is
required for initial installation, or any time the machine is disconnected and/or moved.

3.1.1

Nozzle Flow Controller Verification and Adjustment

Materials required:

•

Scribed reference flow meter supplied with the machine.
