  • a second feeding source 65 feeds the receiver 51 and the oscillator 19. Since the receiving unit 50 always remains turned on and ready to receive signals, its consumption of energy is higher than the consumption of energy of the transmitting unit 40. Therefore, the second feeding source 65 may be either an internal battery or an external feeding source, for example, the conventional electric network, which must supply a 12-Volt voltage around 300 mA of current. Other configurations of voltage and current may also be used.
  • the conventional electric network as a second feeding source 65, it is known that it supplies an alternate current that may be of 110 Volts or 220 Volts. Thus, independently of the voltage supplied to the circuit, the latter is transformed into 12 Volts by a transformer or an equivalent component.

  • the multiple bores 15 are grouped in the fact 16 of the device 14, so that they will remain adjacent the oscillator 19, which is arranged inside the signaling device 14 and that produces the sound alert signal. Therefore, the function of these multiple bores 15 is to exteriorize the sound signal produced by the oscillator 19.
  • the first LED 17 preferably red, it has the function of emitting a luminous alert in order to indicate that the fluid level inside the gas-container 21 has reached the previously defined monitoring point.
  • the second LED 17' preferably green, is intended to indicate the correct functioning of the receiving unit 50, that is to say, if this second LED 17' is on (emitting green light), this means that the receiving unit 50 is functioning correctly; but if this LED 17' goes out (stops emitting light), then this means that the receiving unit 50 has a problem and has stop functioning. In this case, this second LED 17' is also fed by the second feeding source 65.
  • the gas-container 21 is positioned on the platform 1 of the support 100, so that the second end 10b of the indicating pointer 10 is moved in order to be position at one of the strips of the display 5 different from the one that comprises the magnetic sensor 61.
  • the fluid existing inside this gas- container 21 is used, its weight decreases, and the end 10b of the pointer 10 is displaced towards the monitoring strip 7, as shown in figure 5.
  • the coder 43 is also actuated, which modulates the code of the equipment at the signals to be transmitted. Then the transmitter 42 emits coded signals via radio-frequency RF, which are received by the receiving unit 50, positioned in the signaling device 14, which is away from the support 100.
  • the receiving unit 50 receives the signals emitted by the transmitter 42 through the receiver 51 , which then sends the received signals to the decoder 53, so that the latter can recognize the code that has been inserted into the transmission signals. Once this code has been recognized as being correct, the receiving unit 50 simultaneously actuates the time switch 55, which imposes a pre-established time on the oscillator 19, that is to say, the time switch 55 controls the emission of the sound alert produced by the oscillator 19, according to the time already established by the manufacturer. This pre-established time may be, for instance, about 5 minutes.
  • the receiving unit 50 Besides actuating the oscillator 19, in order to emit a signaling sound, the receiving unit 50 also actuates the first LED17, so that the latter will be blinking and signaling to the user that the fluid level inside the gas- container 21 has reached the monitored limit.
  • Both the sound alert and the luminous alert may be manually deactivated by touching the button 18; there may also be the option of automatic deactivation.
  • this device also comprises a second face 23 that is parallel and opposed to the first face 16, on which at least two contact pins
  • These contact pins 24 are positioned. These contact pins 24 are intended to be connected to the terminals of the conventional electric network, when an external feeding source is chosen for the receiving unit 50.
  • the signaling device 14 may be positioned at numberless places away from the support 100; for instance, in the kitchen or in the storeroom, among other rooms of the building.
  • the user does not need to worry about monitoring the consumption of gas by observing the position of the indicating pointer 10 at the display 5, to check the conditions of the gas-container 21 - this practice is troublesome if the gas-container 21 is not close to the stove in the kitchen, but rather in the external part of the house, which is more common.
  • the monitoring of the consumption may be automatically carried out by the electronic system, remotely and by means of sound signals emitted by the oscillator 19 and by the luminous signals emitted by the first LED 17.
  • the present support for gas-containers with a system for remotely monitoring the consumption of gas achieves the proposed objectives, performing, in a practical and efficient way, the functions for which it is intended, providing a number of advantages and benefits inherent in its utilization, with innovatory characteristics.

L'émetteur (42) est actionné par le capteur magnétique (61), dés que le capteur magnétique (61) chevauche un aimant (20) placé sur l'aiguille indicatrice (10); l'émetteur (42) émettant des signaux reconnus par le récepteur (51) qui actionne l'oscillateur (19); l'unité de réception (50) étant placée à distance de l'unité de transmission (40). La présente invention concerne également un support de contenant (100) comprenant le système électronique conçu pour contrôler à distance la quantité de fluides dans un contenant, et un dispositif avertisseur (14) contenant une unité de réception (50) du système de contrôle de fluide.
