Detection device of the position of a measurement module on a fluid meter

摘要

The measurement module (2) reads and transmits data from the rotating disk of the fluid meter (1). The meter and module are in contact at their surfaces (1A,2A). The meter has an electrically conducting plate (10) at the upper surface and the module has two such plates (20A,20B) in the lower surface. The plates form a capacitor whose capacitance may be measured by an electronic card (21) and compared to a threshold Independent claims are also included for the following: (1) fluid flow meter which has electrically conducting plate for use as part of position locating capacitor; (2) measuring module which has two electrically conducting plates for use as part of position locating capacitor.
