    QCM sensors can also measure density-viscosity product in liquids as described below. The sensors are typically circular with about a 10:1 ratio of diameter to thickness; the precise dimension is determined by the desired operating frequency. Typical operating frequencies are about 5 MHz (Martin et al., 1991).
