Abstract
A communication device is disclosed for communicating telemetry data relating to a fluid, which is passed through a group of concatenated containers such as pipes, tanks and the like in a process installation, to a data processing device. The communication device includes a measuring sensor which can be spatially separated from the data processing device, the measuring sensor having a transponder and a converter for converting a physical variable of the fluid into an electrical variable. The measuring sensor can communicate with a reading device assigned to the data processing device, the measuring sensor being concomitantly loosely guided in the fluid.
Claims10
A communication device for communicating telemetry data, regarding a fluid passed through a process installation, to a data processing device, the communication device comprising:
- a measuring sensor configured for spatial separation from a data processing device, the measuring sensor including a transponder and a converter for converting a physical variable of a fluid into an electrical variable, the measuring sensor being configured for operative cooperation with a reading device assigned to a data processing device for contactless communication with the reading device;
- and
- the measuring sensor being configured to move and be guided by the fluid during communication with the reading device.
Method for measuring physical variables of a fluid comprising:
- combining a measuring sensor with the fluid;
- processing the fluid containing the measuring sensor in a process installation, the measuring sensor being guided by the fluid through the process installation into contactless range of a reading device assigned to a data processing device;
- and
- reading data regarding the physical parameters of the fluid from the measuring sensor via the reading device.
