Abstract:

AbstractSolid friction and backlash in the mechanism of a certain fuel density meter are shown to be instrumental in producing apparent density shifts when the meter is in a dynamical environment. This phenomenon, which is essentially one of rectification of a high frequency input signal, along with a related low frequency oscillatory instability phenomenon, is thought to be new and worthy of extended discussion. These phenomena disappear in the absence of backlash and ankylosis.
