A flow rate assembly can include a fluid flow interface portion having a front facing wall and a back facing wall. The flow interface portion can include an inlet passage within the fluid flow interface portion, an outlet passage within the fluid flow interface portion, at least one inlet aperture extending through the front facing wall of the fluid flow interface portion into the inlet passage, and at least one outlet aperture extending through the back facing wall of the fluid flow interface portion into the outlet passage. In some cases, the fluid flow interface portion includes a plug forming at least a portion of the inlet passage. 130.-. (canceled)31. A method of manufacturing a fluid flow sensor , the method comprising:providing a sensor tube;providing a sensor body;connecting the sensor tube to the sensor body such that an inlet passage of the sensor tube is fluidly connected to an inlet passage of the sensor body;inserting a float into the inlet passage of the sensor body via an aperture; andsealing the aperture to enclose the float within the inlet passage of the sensor body.32. The method of claim 31 , further comprising inserting a plug into a recess of the sensor tube.33. The method of claim 32 , further comprising forming at least a portion of the inlet passage of the sensor tube with the plug.34. The method of claim 32 , wherein the plug has a wedge-shaped profile.35. The method of claim 32 , wherein the plug is constructed as a solid part that is absent an internal channel.36. The method of claim 32 , wherein the plug comprises an internal channel that forms a portion of the inlet passage of the sensor body.37. The method of claim 32 , wherein the plug is sized such that a back side of the plug is flush with a back side of the sensor tube.38. The method of claim 32 , wherein the plug is separate from the outlet passage of the sensor tube.39. The method of claim 31 , wherein the sensor tube is formed by an injection molding.40. The method of claim 31 ...
