Abstract: Temperature compensation of diaphragm meters was Introduced in 1957. A revolutionary concept at the time, years of experience have varified both the accuracy and value of temperature compensation for diaphragm meters. The development of internal temperature compensation for diaphragm meters was the result of a number of Influences. Both the value and the consumption of gas was increasing markedly during the 1950s. Heating loads were being added to existing cooking and hot water loads creating a seasonal variation not generally experienced before. A growing trend toward outdoor sets with the availability of synthetic diaphragms placed the meter in a varying environment. It is the environmental effects - greatest consumption when the weather Is coldest - that spurred adoption of temperature compensated diaphragm meters by gas distribution companies.
