| To Bn.{W.O. Bentley / Mr Barrington} from EFC. EFC1/AT20.5.19. RE PETROL FLOW METERS. X.3180, X.2229, X.3359 In answer to your enquiry Bnll/P16519, I am sending down to you files containing matter in connection with Petrol Flow Meters as follows:- X.2229.- R.A.E. Petrol Flow Meter. X.3180.- Venturi " " X.3359.- Cowey " " The first of the above was an experimental meter made and tried out by the R.A.E. (then R.A.F.) We had one of these along to try, but we did not find that the results were by any means satisfactory. The second of these was a meter I thought out and experimented with a good deal, and which you will see, by a certain report of Mr. Platford's, gave very good results. The meter, however, was not seriously taken up by us owing to the difficulty of getting the apparatus made, else it was our intention to have these fitted in every test house for use on the aero engines. (I might mention in passing that we have used water flow venturi meters experimentally on the engines with great success, these too being our own idea). No doubt you will have seen the article in the current number of the Automobile Engineer on Petrol Flow Meters. I have not had time to go through this properly, so far, but I know that Mr. Platford has used, in the test house, flow meters of the type illustrated in Fig. 14 on page 44 and has found these fairly successful.
