windometer 

Plain and simple: an anemometer.
An anemometer is an instrument used for measuring wind speed.

Winds were clocked with my stupid sodding "rotten cat pee yellow" portable digital "windometer" (as JD from JD Quad in the UK calls them even though those things are actually called, "anemometers") ;-) as being variable to 3.60mph (4.36kph) at the surface.

wankometer 

It's a device to measure how many wanks you are doing to the hour.

"Oy! You filthy little pervert! You were doing at least 40, and this is a built up area!"

"Sorry officer, I think my wankometer must be broken."

"OK sir put that throbbing red rod back in your trousers and we'll say no more about it."
