Abstract: An accessory apparatus for flowmeters, especially for ultrasonic flowmeters having at least two successively arranged, plate-shaped or disk-shaped flow influencing elements (1, 2) which are provided with recesses and which are located downstream and/or upstream of the flowmeter, the recesses in the flow influencing elements (1, 2) being made and/or the flow influencing elements (1, 2) being arranged in a manner eliminating an unobstructed line of sight in the flow direction. The recesses in the flow influencing elements (1, 2) of the accessory apparatus are slots (3, 4) which are offset so that a line of sight through the accessory apparatus is eliminated.

Abstract: An apparatus for detecting an anomaly in a flowing stream includes a set of blades rotatably suspended in the flowing stream and aligned with a normal flow direction of the flowing stream. The blades are configured to rotate at one rate when the anomaly is present in the flowing stream and to rotate at a different rate when the anomaly is absent from the flowing stream. A device is prescribed for measuring rate of rotation and rotation direction of the blades.

Abstract: The invention provides a liquid meter comprising a measurement chamber in which a spinner is caused to rotate about an axis and pivots, at least at low liquid flow rates, on a support in alignment with the axis. The pivoting motion takes place via a ball that is free to rotate between two concave surfaces each having a radius of curvature that is greater than the radius of curvature of the ball. One of the concave surfaces is tied to the spinner, whereas the other surface is secured to the support.

Abstract: The device is used to determine the flow rate of a medium, e.g. of a fluid or a gas, including a housing (1) with a chamber (2) through which the medium is axially flowing and which receives an impeller wheel (10) with one blade (13), whereas the impeller wheel (10) is provided with a carrier body (12) having a centrical boring (15) for receiving an axle (11), whereas the carrier body (12) is provided in the area of the axle (11) with at least one opening (12a) running radially to the centrical boring in the carrier body (12), whereas the axle (11) is arranged in the carrier body (12) by at least one, preferably two radial bearings (17, 18), whereas a radial allowance is provided between the boring of the carrier body (12) and the axle (11), whereas, due to the radial allowance between boring (15) in the carrier body (12) and axle (11), water is entering at the open side of the boring (15) and is exiting through the radially running opening (12a) in the carrier body (12).

Abstract: A water softener valve for controlling water flow to and from a water softener is disclosed that includes a cylindrical shaft extending from said inner surface of a piston chamber that fits into a pressure relief port when the piston is in the service position. The shaft clears the pressure relief port of any debris and closes the pressure relief port during the service cycle. The water softener valve also has a flow meter with at least two helically expanding vanes. A magnet on of the vanes trips a sensor as the turbine rotates, thereby providing means for calculating the flow of water through the valve. The valve also has a flow control button located at an inlet of the valve rather than at the drain, preventing the obstruction of the water flow by regeneration sediment of the tank at the drain. The valve also contains an internal piston port for permitting the free flow of water through the valve during a change in softener cycles.

Abstract: The present invention relates to a cyclone turbine flowmeter for extracting information about a flow rate or measuring the quantity of flow flowing in production facilities. The cyclone turbine flowmeter includes a cyclone turbine formed with flow channels for allowing liquids flowing in from the outside to receive rotary power, a rotor rotated by the liquids passed through the flow channels of the cyclone turbine, a turbine bearing manufactured so as to minimize frictional forces and at the same time, to have durability and resistance to chemicals, and a vibration isolation bearing constructed in such a manner of enclosing the turbine bearing and its turbine axle to prevent vibration.
