ABSTRACT:
Adjustment of a gas regulator valve having a spring biased diaphragm controlled pilot valve is automatically effected by supplying augmenting pressure to the spring side of the diaphragm via an electrically adjustable regulator valve under the control of a local microprocessor. Historical pressure drop data as a function of day of the week, time of day, and ambient temperature is stored in the microprocessor. A temperature sensor provides the microprocessor with a signal indicative of ambient temperature, and this is correlated with the stored historical data to determine the adjustment for the main regulator valve.
