The article proposes a device for measuring parameters of liquid flows (volume and velocity) (FOSLFP). A physico-mathematical model of optical signal conversion in a fiber-optic flux transducer of the proposed sensor is developed, in which the perceiving element is a truncated cylinder mounted on the inner surface of the bellows, experiencing angular bending during measurements. The conversion of optical signals is carried out using a two-way mirror plate mounted on the outer surface of the bellows in an open fiber optical channel. A circuit-analytical model of a new variant of a differential circuit for converting optical signals to a FOSLFP was developed, in accordance with which a metrological model of the sensor was developed to determine the possible sources of measurement errors. The nominal and real functions of the FOSLFP transformation were derived, the additive and multiplicative components of the errors of the two measuring channels of the sensor and the ways to reduce them were determined.
