What you refer to is the "downdraft" style Bosch K-Jetronic air flow
sensor.  It was primarily used by Mercedes, usually located under the
large air cleaner cover in the middle of their V8 engines (which makes it
look like a carbureted car.  There is nothing inherently wrong with
the downdraft version v. the "updraft" style that is used on VWs,
Audis, Volvos and Saabs.  The fuel distributor rod rides on the
opposite side of the fulcrum, and the sensor plate is in an inverted
cone funnel, but otherwise works the same.  The sensor plate is
counterweighted such that the fuel system's control pressure is what keeps
the plate from overshooting.
