%X An optical fiber Fabry-Perot cavity liquid level sensor with anti light source fluctuations and disturbances using interference fringe counting technique is developed.Flexible metal bellows,which can afford a large strain displacement,is suggested to be one surface of the F-P cavity.Both the hardware electronics design scheme and the software treatment methods are developed to count the fringes and determine the up or down of the liquid level.A design for compensating the temperature affection is suggested.The liquid level sensor is fabricated;the practical measurements is carried out both for the air pressure and the water level.
