Abstract:

The purpose of this study is to set forth the procedures and criteria for the acceptably accurate measurement of the true average steady-state static pressure in fluid power systems. The scope is limited to the measurement of average steady-state static pressure in closed conductors, which are transmitting hydraulic fluid power. Fluid velocities are less than 25 metres per second. Pressure pulsations with peak-to-peak amplitudes are less than 100 of the average steady-state static pressure. Carrying fluids have specific gravities between 0.6 and 1.2. Average steady-state static pressures are less than 700 bar. Inside diameters are greater than 3.0 millimetre. Excluded are the criteria for the location of pressure taps upstream and downstream of flow disturbances, such criteria being within the scopes of the specific component or system test procedure standard. Included are those identifiable effects which contribute significantly to the total error in pressure measurement.
