Click the [Calculate] button. The FS200 Clamp-On gas tool will compute the
recommended sensor type and size for your specified pipe. Typically, only High Precision
sensors are suitable for gas applications and will be the primary selection. The tool will
also provide sensor mounting mode and spacing information. An example appears in
Figure 6-4 below.

[Installation Calcs] and [Repeatability Graph]. You may click on the appropriate tab for
specific details related to the application you programmed. The data shown under each
tab is relative to the application parameters you entered for pipe dimensions, gas type,
flow, temperature and pressure in the Gas tool. Should an application conflict exist it will
alert you with an "Application Problem" message.
Click on the [gas process calc] tab for application information on the theoretical values for
compressibility factor, Sg, Speed of sound, Volume compensation, flow velocity, Viscosity,
and Reynolds number over your specified application range.
