Fraud detection method of a fluid meter and fluid meter with a fraud detection device

摘要

A procedure consists of fitting a meter (22) containing a counter mechanism (46) and display (52) with a cover (50) that has at least part (54) made from a material that has a low level of stress resistance no more that 10 per cent elongation at rupture - and leaves visible cracks if a pressure is applied to it. - The procedure consists of fitting a meter (22) containing a counter mechanism (46) and display (52) with a cover (50) that has at least part (54) made from a material that has a low level of stress resistance no more that 10 per cent elongation at rupture - and leaves visible cracks if a pressure is applied to it. The cover part can be in the form of a replaceable tamper-indication module; it can make up at least part of the meter window and fixed to the meter by a system that shows if the module has been taken apart.
