Carrier for mass air flow production line

A carrier for the assembly, test and calibration of a mass air flow sensor on a production line. The support carrier consists of a structure having a well for receiving a first portion of the sensor head of the mass air flow sensor and a transverse air flow passage provided through the support structure aligned with the well and parallel to the top surface of the support structure. A clearance aperture connects the bottom of the well with an air flow passage and permits the sensor elements of the mass air flow sensor to be centrally disposed in the air flow passage. Sealing surfaces provided at the opposite ends of the air flow passage permit the carrier to be connected to a controlled source of air. Locating pins align the mass air flow sensor on the carrier with the sensor elements accurately positioned in the air flow passage.
