Dear Sir, Re - Flow Meters for air supply to internal combustion engines. Many thanks for your letter to our Mr. Clough, enclosing pictures of three sizes of your Flow Meters. We are interested in this at the present moment, as we want to have some means of measuring the air supply to our engines. The meters illustrated would appear to be quite convenient instruments. The only point about which we should be in doubt would be as regards accuracy. We should be glad if you could give us some idea as to percentage accuracy obtainable with these meters, and how this accuracy would be affected by variations in the conditions of the | ||
