ОписаниеVibrating wire piezometer from USBR 6515-09 Fig. 1.png
English: A vibrating wire piezometer from Figure 1 in USBR 6515, "Procedure For Using Piezometers to Monitor Water Pressure in a Rock Mass". Piezometer.-A vibrating wire piezometer, commonly used by Reclamation, is shown on figure 1. Its stainless steel housing nests the different components of the piezometer such as (1) the filter, (2) the diaphragm, (3) the vibrating wire, (4) the plucking and pickup coils, (5) the internal bulkhead seal, and (6) the cable connectors. The vibrating wire converts the fluid pressures into equivalentfrequencysignalsthatare then recorded. The piezometer pressure range could be 0.034 to 34.5 MPa (5 to 5,000 lbf/in2) with an accuracy of ±0.5 percent.
