Temperature correction functional attaching film type gas meter

摘要

Abstract Topic Gas amount used of film type gas meter for home high order accuracyYou weigh. Solutions In 1st metrical space 28a, 1st metrical film 26a to be provided round trip displacement possibly, 1st metrical film 26Magnet 64 is concatenated to a. Displacement detection sensor 6As for 5, in every approach of magnet 64 displacement inspection of 1st metrical film 26aOut, the signal is generated, temperature sensor 63 detects the temperature of the gasru. In micro-computer 56, the body of the gas which is generated by temperatureMechanical metrical error of the product being required beforehand, to be stored,ru. As for micro-computer 56, according to the displacement detection signal cubic measure of the gasTo seek, responding to the output of temperature sensor 63, the Boyle plain gauzeOn the basis of the doctrine and aforementioned mechanical metrical error of ru aforementionedAmendment the cubic measure of the gas which it requested. Hardening in the low temperature of metrical filmWith the temperature correction which considers do mechanical metrical error, the gasAmount used is weighed to high order accuracy.
