As another benefit, Web Presenter (and the Teranex Mini Smart Panel) provides a volume meter
on the front panel, which you can see in the low green in Figure 1.
After you enable manual gain control and set the volume controls at mid-level, if the volume is bumping against the top of the volume meter
, you should try attenuation.
There are many pitfalls at this stage including volume meters
inferring mass consumption, meters installed incorrectly and meters oversized due to confusion over Normal, Standard, Free air delivered or actual volume units.
For example, solar-powered models are in service along natural gas pipelines where they are connected to data recorders for flow and volume meters
. Solar-powered systems are also used in monitoring the environment.
