A flow device is provided for sensing air flow and includes a body having at the opposite ends thereof coaxial bores. Counterbores extend inwardly from the coaxial bores and are interconnected by a restricted bore having lateral bores extending from opposite ends thereof to provide a pneumatic pressure drop. The bottom portions of the respective counterbores are relieved to provide a pair of troughs for water collection outside of the normal air flow area so that water can accumulate for an extended period of time before interferring with pressure drop readings.
