<p>A calibration method is proposed to improve pressure calibration that uses a pressure gauge as the reference device. The reference gauge is pressurized by a 0-A-0 pressurization procedure, whereas the test gauge can be pressurized through various procedures. The calibration results with this method were consistent with those calibrated against a pressure balance. The method is expected to help develop low-cost pressure calibration systems that are more precise.</p>

Flow Through

The flow of a liquid through a tube deformed by a piezoelectric cell under a harmonic law is studied in this paper. Linear deformations are compared for the Dirichlet and Neumann boundary conditions on the contact surface of the tube and piezoelectric element. The flow of fluid through a deformed channel for two flow regimes is investigated: in a tube with one closed end due to deformation of the tube; for a tube with two open ends due to deformation of the tube and the differential pressure applied to the channel. The flow rate of the liquid is calculated as a function of the frequency of the deformations, the pressure drop and the physical parameters of the liquid.
