Abstract
A battery/self powered electronic pressure gauge having electronic measurement, control, output, and display capability is described having the flexibility of using a sampling rate that is variable, based on either a random sampling scheme or one that learns from the history of use during the previous minutes, hours, days, months, etc. The variable sampling rate enables extended operational time before replacement of the battery. The pressure gauge can be configured to sense “intent” to change pressure in the outlet line and to revise its sampling protocol. This “intent” can be defined by the detection of the proximity of a user's hand to the pressure regulator.
