Meter for a fluid

Meter a fluid, the meter comprising:

• a casing configured to be crossed by the fluid to be measured,
• an inlet mouth and an outlet mouth for the passage of a flow of said fluid, respectively entering inside the casing and exiting the casing,
• a detection module which is housed in said casing and which is configured to detect one or more quantities relating to said fluid passing through said casing,
• a processing section which includes:
• a first containment structure which is external with respect to the casing,
• a first electronic control and/or processing unit which is housed inside the first containment structure and which is electronically connected with said detection module, to thus receive and/or process signals representative of and/or or derived from the quantities detected by said detection module,
• first optical communication means which are mounted on and/or housed in said first containment structure and which are electronically mounted on and/or connected with said first electronic unit,
• a communication section which includes:
• a second containment structure which is external with respect to the casing,
• a communication module for transmitting and/or receiving data via radio with the outside of the meter,
• second optical communication means which are mounted on and/or housed in said second containment structure,
• a second electronic control and/or processing unit which is housed in said second containment structure, said communication module and said second optical communication means being electronically mounted on and/or connected with said second electronic unit,
• wherein:
• said first containment structure and said second containment structure are configured to be mechanically associated with each other in a removable manner and so that, when said structures are mechanically associated with each other, the first optical communication means are capable of communicating with the second optical communication means, to thus define an optical communication interface between the processing section and the communication section
• said first containment structure includes a receiving portion and said second containment structure includes an insertion portion, or vice versa,
• said insertion portion is configured to engage within the receiving portion to thus define an optical communication channel which is protected from external access of liquids and solid particles,
• said first optical communication means are mounted in correspondence with said receiving portion and in that said second optical communication means are mounted in correspondence with said insertion portion, or vice versa.
