7.1.2.1. DAS CHANNELS
The key to the flexibility of the DAS is its ability to store a large number of
combinations of triggering events and data parameters in the form of data
channels. Users may create up to 50 data channels and each channel can contain
one or more parameters. For each channel, the following are selected:

PNUMTC: Collects sample flow and sample pressure data at five-minute
intervals and stores an average once a day with a time and date stamp. This data
is useful for monitoring the condition of the pump and critical flow orifice

pressure) over time to predict when maintenance will be required. The last 360
