The sensor is choosen by the FIA, not the teams themselves (even if they have their own flow rate sensors). So there is no way for the teams to find an interpretation of that : flow rate is given, sensor is given.Maxion wrote:Agreed, but there is no specification of measurement period in the technical regulations. The rule is stated with a measurement period of kilograms per hour. Using logic, one would assume then the measurement period to be one hour, no? The, to be compliant with the rule you cannot use more than one hundred kilograms of fuel in a one hour period.Lurk wrote:100kg/h = 2.56g/0.2s = 2.4ton/day.
It is a rate flow! It has no notion of frequency, therefore it must be respected all the time. The measure is done 5 times per second only because it is convenient. If they could have a continuous analogic measurement, they would have one.
Doing so you are in breach of the intent of the rule, but you are technically speaking not breaching it. With the technical regulations intent matters not, only technical compliance.
If the FIA intended this rule to be interpreted with a 10 Hz measurement period, then why is the flow limit stated as being per hour?
As I said, it FIA found a way to have a continuous analogic measurement they would have done that.
BTW don't forget the regulation that appears on FIA website is not the complete one. There is also all the technical notes send by Charlie, and I'm pretty sure something like how this sensor works was described in it.
edit @Paul: maybe it is a stupid question, but could it be done from fuel pump directly?
Anyway, they works on computer so they would still have a discrete, numeric measure in the end.
