Title:
GAS METER FOR THE MEASUREMENT AND STANDARDIZED METERING OF A GAS STREAM
Document Type and Number:
WIPO Patent Application WO2002073141
Kind Code:
A3
Abstract:
Gas meters, particularly industrial bellows-type gas flow meters, rotating piston gas meters and turbine flowmeters, have the following drawback in that due to the prescribed mechanical reading of the meter result, which occurs in the pressure area of the gas meter and which is used for testing and calibrating purposes, the entire meter including pressure cases has to be brought, in most cases, to remote testing stations. A novel counting chip (14), which is supplied by the counting pulses alone without any additional power supply and which generates a meter result that can be stored, enables a conventional electronic or mechanical counting mechanism to be used for displaying, remote reading or billing purposes. The counting chip (14) is thus used for storing the meter result. In order to check and/or read out the meter result, the counting chip (14) is connected to an external power supply.
