Title (EN) DEVICE FOR MEASURING LIQUID LEVEL IN A TANK
(FR) DISPOSITIF DE MESURE DU NIVEAU DE LIQUIDE DANS UN RESERVOIR
Abstract:
(EN) The invention concerns a device for measuring liquid level in a tank (R) comprising a probe (10) and, connected to said probe (10), a processing circuit (12) adapted to supply a signal representing the liquid level in the tank (R). The probe (10) comprises a transmitter antenna (14) and a receiver antenna (16), the two antennae (14, 16) immersed surface being a function of the liquid level. The processing circuit (12) comprises a generator of electric signals (18) connected to said transmitter antenna (14) and, connected to said receiver antenna (16), means (24) converting the amplitude of the electric signals received by said receiver antenna (16) from said transmitter antenna (14) into the signal representing the liquid level in the tank (R). The invention is applicable to level sensors in a motorised bike tank.
(FR) Le dispositif de mesure de niveau de liquide dans un réservoir (R) comporte une sonde (10) et, relié à ladite sonde (10), un circuit de traitement (12) adapté pour fournir un signal représentatif de la hauteur du liquide dans le réservoir (R). La sonde (10) comporte une antenne émettrice (14) et une antenne réceptrice (16), la surface immergée des deux antennes (14, 16) étant fonction de la hauteur du liquide. Le circuit de traitement (12) comporte un générateur de signaux électriques (18) relié à ladite antenne émettrice (14), et reliés à ladite antenne réceptrice (16), des moyens (24) de conversion de l'amplitude des signaux électriques reçus par ladite antenne réceptrice (16) depuis ladite antenne émettrice (14) en le signal représentatif de la hauteur du liquide dans le réservoir (R). Application aux capteurs de niveau de carburant dans un réservoir de cyclomoteur.
