Flowmeter

Patented Cemes

Flowmeter in short
Borne out of experience in racing and those seeking the best. This is no approximate job but one carried out with concrete numbers and the guarantee of results. Managed by technicians under technical supervision so as to have certain data which can be found on the test bench once the preparation work on the head and any thermal group subjected to the passage of gas is finished (2 stroke, 4 stroke, diesel, carburetors, etc.). It has a hardware and software system of first rank complying with EEC norms and a 1-year warrant.
The flowmeter in the photos is specific equipment for sale to preparing and technical mechanics in the car and motorbike sectors.

Il Flussometro (Flow Bench): cos'
The flow bench is the instrument for measuring flow in its quantitative aspects: volume and speed, guaranteeing a critical-construction analysis of the fluid dynamics which regard the development of power which would otherwise be the realm of anachronistic ideas more fit for witch doctors than serious preparers.
With this instrument the initial values of various thermal groups can be read (4t heads, 2t cylinders) and after that, after the appropriate intervention the results can be read and alternatives can be explored to further improve performance. Finally it allows one to hypothesize performance (rather accurately) which a particular apparatus may reach. All before the engine is even assembled.

The immense advantage which this measuring and analysis instrument  provides, consists in having a first rate technical approach, thanks to the individuation of sonic areas (in which faster than sound speeds can be reached) or areas of stalling (where on the contrary there is stagnation, no speed), at this point the Pitot tube and differential manometers will provide certain data.
Appropriate hardware and software support will accelerate reading times and guarantee the continuity and repetitiveness of results.
The flowmeter can test valves, conducts, valve seats, profiles, lifts, etc. Making the preparation work faster and more certain.

dimensional mesurements:
In full accord with the flow bench often moulds are used, made out of silicone rubber so as to find any defects: in the design of conducts, in shape, or “hidden” height variations difficult to see with the naked eye. Thanks to this work method the possibility of ending up on the water or outside is reduced to a minimum.
The two superimposed work methods make sense once the preparation work is finished, when one reaches the test bench where calculations, like experimentation, become a certainty, concrete and tangible in a reading of performance reached on the test bench.
