  • the strain sensor may be arranged at the body of the device, such that the strain sensor is arranged between the valve body and the device and is accordingly compressed upon attachment of the device to the gas cylinder or valve body.
  • a lower strain measurement or lack thereof may indicate a loosening or separation of the device.
  • the output of the strain sensor may correspond to a force being applied to the valve body or electronic module, which may result in a shift of the position of the device and may be comprised in the outputted signal of the evaluation unit.
  • the evaluation unit may be configured to not only determine a deviation of the strain sensor, but also to correlate or match a particular distance to the measured sensor value in order to determine a distance between the device and e.g. the valve body. Said distance may then be compared with a predefined distance corresponding to the predefined position, which is preferably dependent on the type of gas cylinder, a type of valve, and/or a type of electronic module.

  • the magnetic element may also be provided in the electronic module, e.g. in the form of a solenoid control element or valve, such that the first part may alternatively be an integrated part of the electronic module and is not comprised in the device itself.
  • the evaluation unit may hence automatically detect a change in the current in the electric circuitry upon coupling the device to e.g. the valve body of the gas cylinder due to the presence of at least one magnetic element in the valve body, wherein the predefined position may be based on a particular current corresponding to the type of gas cylinder, a type of valve, and/or a type of electronic module.
  • the detection unit may comprise an acoustic transmitter for outputting an input acoustic signal toward the gas cylinder and/or the valve of the gas cylinder and a receiver for receiving a reflected acoustic signal, wherein the evaluation unit is configured to determine the position based on a determined difference between the input acoustic signal and the reflected acoustic signal.
  • the position may be determined based on a detected difference in the amplitude, phase, and/or frequency between the input acoustic signal and the reflected signal, wherein said difference may be dependent on e.g. the type of gas cylinder, a type of valve, and/or a type of electronic module.
  • the acoustic signal is an ultrasound signal.
