An LED irradiates a light ray to the taper-shaped tube and the float, makes the light ray to transmit through the taper-shaped tube, and generates a transmitted light ray. The image sensor outputs a digital image of the float within the taper-shaped tube, and a control portion 11 executes an input process of the digital signal detects the position of the float, and outputs an electric signal showing a flow rate of the fluid.

Abstract: A poppet valve assembly is provided for use on a fuel tanker truck which enables the truck's driver to determine whether fuel is flowing through the valve assembly and whether fuel is present in the valve assembly. When a threshold flow rate through the valve assembly is reached, fluid flows inside a flow channel. The flow channel has a fluid indicator and a flow indicator therein mounted in a sight glass. When fluid is flowing in the flow channel both indicators rise. When fluid is present but not flowing in the flow channel only the fluid indicator rises. The fluid and flow indicators, being different colors, may be easily seen at a distance.

Abstract: A device for converting a position of a float member in a rotameter in to an electrical output. Light from a light source is collimated into parallel light rays, at either or both opposing sides of a rotameter tube to greatly enhance accuracy of readings. The lightrays passing through the tube are detected by a linear optical array. A range of movement capable of being read by the linear optical array is extended by use of either a fiber optical array or a movable illumination device and linear optic array. The collimator(s) may be a linear array of one or two rows of cylindrical lenses sandwiched between a pair of plates. The linear optic array maybe arranged on opposite sides of the rotameter tube or may be on the same side there of. A light guide is used in the latter arrangement to guide light from the light source to a side of the rotameter tube opposite the linear optic array which may be a charge-coupled device(CCD).

Abstract: An improved fluid flow measuring device having more nearly linear response characteristics over a wide range of fluid flow rates measures the force exerted on a fluid flow sensing element (21, 37, 41, 47, 55, 61) located in the fluid flow. The effective area of the sensing element subjected to the fluid force decreases as the flow rate increases and increases as the flow rate decreases thereby compensating for the nonlinear relationship between fluid flow rate and the force exerted thereby. The sensing element may retract somewhat into a calm or minimal flow region (27, 35) in response to increased flow rate. The sensing element may include resilient vanes (45, 51, 52, 53, 57, 59) which bend thereby reducing their effective area in response to increased flow. The sensing element may include one or more flow passing apertures (43, 49) the size of which varies with flow rate.
