Frequently asked questions

To change the gas type, cycle through the Gas select mode using the MODE button until the dynamic label over the button reads Gas. This mode displays a list of gas types. Use the UP and DOWN buttons to position the arrow in front of the desired gas. Once the mode is cycled back to the main mode, the selected gas will be displayed on the main screen.

You can set the flow rate either locally or remotely. To set it locally, select Local input in the Control Setup Mode. Then, use the UP and DOWN buttons to adjust the Set Point value. For remote control, use either an analog signal or a RS-232 connection. Refer to the installation section for detailed information on configuring these settings.

Volumetric flow measures the volume of gas passing through a point per unit time, while mass flow measures the mass of gas passing through a point per unit time. The difference between them lies in the density of the gas. At room temperature and low pressures, volumetric flow is nearly identical to mass flow. However, as temperature and pressure increase, these rates can vary significantly. For applications where mass is crucial, a mass flow controller is necessary. Refer to the section "Understanding Volumetric and Mass Flow" for a more in-depth explanation.
