Flow sensing device and associated method

A flow sensing device comprising:

• a housing;
• a printed circuit board assembly (PCBA) at least partially disposed within the housing, the PCBA having a first major surface and an opposing second major surface, and the PCBA defining at least a first PCBA through-hole and a second PCBA through-hole;
• a sensing element disposed on the first major surface of and in electronic communication with the PCBA;
• and
• a flow tube at least partially disposed within the housing and at least partially defining a flow path configured to convey a flowing media through the flow sensing device, the flow tube comprising (i) an elongated main body disposed proximate the first major surface of the PCBA, (ii) a fluid inlet tube in fluid communication with the main body and defining an opening for the flowing media to enter the flow tube, and (iii) a fluid outlet tube in fluid communication with the main body and defining an opening for the flowing media to exit the flow tube;
• wherein the flow path is disposed proximate the sensing element such that at least a portion of the flowing media makes direct contact with the sensing element;
• and
• wherein the flow tube is disposed such that (i) the elongated main body is proximate the first major surface of the PCBA, (ii) the fluid inlet tube protrudes through the first PCBA through-hole to position the opening of the fluid inlet tube proximate the second major surface of the PCBA, and (iii) the fluid outlet tube protrudes through the second PCBA through-hole to position the opening of the fluid outlet tube proximate the second major surface of the PCBA.
