Device for measuring a fluid

Device for measuring a fluid, the device configured to measure a flow rate of gas or liquid circulating within a pipe and through the device, the device comprising:

• a containment structure which is provided with a first opening for the inlet of the fluid therein and with a second opening for the outlet of the fluid,
• said containment structure being configured to define inside it a path for the fluid between said first opening and said second opening, said path comprising:
• an internal tubular section which extends in a substantially rectilinear way along a longitudinal axis X and which is in direct fluid communication with said first opening for the inlet of the fluid,
• at least two external chambers for subdividing the fluid flow, which are positioned around said tubular section and which are in fluid communication with said second opening for the outlet of the fluid, so that the fluid flow first passes through said internal tubular section and then said at least two external chambers,
• said at least two external chambers being fluidly connected with said internal tubular section in correspondence with an area of the internal tubular section which is opposite to that in correspondence with which said tubular section is in fluid communication with said first opening for the fluid inlet,
• sensor means configured to detect a quantity of the flow of said fluid that passes through said internal tubular section, wherein said containment structure comprises:
• a first body in which said first opening and said second opening are formed and which is configured to be mechanically connected between an upstream pipe and a downstream pipe that are external to said device,
• a second body in which said sensor means are mounted, and wherein:
• said internal tubular section which extends substantially rectilinearly along the longitudinal axis X is defined and/or formed partly in said first body and partly in said second body, said at least two external chambers being defined and/or formed, at least in part, in said second body,
• said sensor means comprise at least one ultrasonic emitter and at least one ultrasonic receiver mechanically mounted on a wall which internally delimits said internal tubular section,
• the internal wall is equipped externally with ribs, which protrude towards an internal surface of the containment structure to thus define said at least two external chambers which extend parallel to each other and to the prevailing longitudinal axis X,
• the at least one ultrasonic emitter and the at least one ultrasonic receiver of the sensor means are inserted in seats obtained inside the ribs and are connected to electrical connection means which protrude externally from the containment structure.
