METHOD AND DEVICE FOR SENSING LOCATION-DEPENDENT STATE VARIABLES IN PIPELINES

摘要

The invention relates to a method for sensing location-dependent state variables in pipelines (1) by means of at least one wireless measuring probe (2) in at least one segment (3) of a pipeline system (4), preferably in a substantially vertical segment (5), in particular in a geothermal probe (6). In order to continuously sense the state variables, the liquid medium (7) in the pipeline system (4), according to the invention, is circulated by means of a pump (8), and the at least one measuring probe (2) is circulated in such a way that the at least one measuring probe is guided past the circulating pump (8) by means of a bypass (9). Therefore, data can be obtained in each circulation. The time resolution corresponds to the duration of a circulation. The invention further relates to a bypass for the wireless measuring probe (2) for bypassing a circulating pump (8) and to a pipeline circuit (4) having a measuring probe (2), in which pipeline circuit a bypass (9) is provided for the measuring probe (2) for bypassing the circulating pump (8). Finally, a wireless measuring probe (2) is characterized in that the measuring probe (2) is designed as a sphere (33) having a diameter (22) between 5 and 25 mm and contains an inductive transponder coil (21) for transmitting energy and data.
