BG105464A - Device for pressure measurement and monitoring system for its application - Google Patents

Abstract

The device and the system are used in measuring and control systems for the measurement and monitoring of the full porous pressure, the hydrodynamic pressure and the level of the depression curve in dams, slurry ponds, slag heaps, slime ponds, landslides, monitoring boreholes and other systems applied in the hydraulic engineering. They are used for the measurement, memory storage and transmission all changes in the pressure, regardless of the reasons causing it. The device (1) includes a sensor for pressure measurement (2) fitted in a piezometric tube (8) connected by its upper end to a metal box (10) in which memory device (5) and the transceiver unit (6) are mounted, power supplied by storage batteries (7). The piezometric tube (8) has lightening protection (9). In the tube (8) more than one sensor are fitted for measuring the pressure (2), each of which is coupled by its cable (3) to an analysis and control unit (4) in which the timer is built-in. Above the analysis and control unit (4) the memory storage device (5) and the data transmitter executed in the form of a transceiver unit (6) are fitted. The system includes means for measuring the pressure, representing n-number of devices for measuring the level of the depression curve (16), n-number of devices for measuring the hydrodynamic pressure (17), n-number of devices for measuring the porous pressure (18) and n-number of devices for measuring full pressure (19) One each of every measuring device (16, 17, 18 and 19) is grouped in a module. Each module is assembled at the intersection points between inter-perpendicular profiles (20) and rows (21), conventionally formed in body (22) on the wall. Each of the measuring devices (16, 17, 18 and 19) of the module is coupled to a transceiver module (12) of the receiving station. 4 claims, 6 figures
