| -2- EFC1/AT20519. Contd. more elaborate affair than our simple venturi flow meter, but no doubt gives very fair results. If it were possible to produce an accurate low reading differential low pressure gauge, the application of this to the simple venturi type, which we have made and tried, would result in an instrument which might be conveniently carried on a plane and give fairly reliable readings, at any rate for horizontal flying.
