METHOD, SYSTEM AND PREFABRICATED MULTI-SENSOR INTEGRATED CABLE FOR DETECTION AND MONITORING OF A FLUID FLOW, IN PARTICULAR OF A FLUID FLOW IN FILTRATION PROCESSES, ESPECIALLY OF LEAKAGE IN CONSTRUCTIONS AND/OR IN GROUND

摘要

Method of detection and monitoring of a fluid flow, in particular of a fluid flow in filtration processes, especially of leakage in constructions and/or in the ground, wherein a heat generator (5) and a prefabricated multi-sensor integrated cable (K) comprising at least two temperature sensors (4), at least one power line (6), at least one data line (7), preferably at least one amplifier, and optionally an A/D converter, a memory, and an identification and communication unit, all secured in a cable tube (1), are introduced into a monitored environment (2) and connected to a power source (3a) and a control and recording unit (3) comprising a means for acquisition, recording, processing and visualization of measurement data. Spatial position of each temperature sensor is determined in the monitored environment. The heat generator is fed with a current controlled by the control and recording unit according to selected algorithm. Temperature of monitored environment in function of space and time is measured with use of the temperature sensors. Produced data are transferred to the control and recording unit where these data are recorded and processed to obtain spatial and temporal distribution of temperature in monitored environment. This distribution is visualized and/or stored in a memory unit of the control and recording unit. A measuring system and a prefabricated multi-sensor integrated cable are proposed accordingly.
