摘要： A valve incorporates a device causing turbulents in the water stream just before passing over the turbine fins of the flow sensor. The device actually increases the Reynolds number or turbulence of the water stream increasing the contact of the water on the turbine. This causes the turbine to rotate more efficiently for the given flow volume passing over the flow measuring device. The improved efficiency results in better accuracy and performance over the entire flow range. In one embodiment the turbulent device forces the flow stream to rotate counter clockwise and hit the turbine fins causing higher force which makes the turbine turn more efficiently. The turbine is designed such that the major portion of the fin surface area is perpendicular to the turbulent flow stream. This opposed direction causes more force to be placed on the turbine fin by the water stream.

摘要： A water meter has a meter register having an encoder having electromagnetic wave emitters, e.g., infrared emitters to measure water flow and direction of water flow through the meter. The encoder has two of three spaced emitters directing infrared rays at predetermined time intervals toward a rotating detector wheel having a reflective surface portion and a non-reflective surface portion facing the emitters and an infrared sensor. The reflective surface portion of the detecting wheel reflects the infrared rays incident thereon toward the sensor. A microprocessor connected to the sensor acts on signals from the sensor to determine material flow. The meter register transmits the signal to a distant receiver. The microprocessor of a meter register has an algorithm to prevent the meter register from sending signals until after the meter register or a water meter having a meter register is installed and water moved through the meter.

摘要： A lower cost turbine flow meter comprised of an inner housing constructed out of a high permeable material surrounded by an outer housing constructed out of a lower cost, lower permeable material. A port is placed in the outer housing that runs down to the surface of the inner housing to detect the rotation of turbine rotors that rotate inside the meter as fluid or gas flows through the meter. A pickoff coil is placed in the port to generate a magnetic signal to penetrate through the inner housing wherein the turbine rotor vanes superimpose a pulse signal on the magnetic signal. The lower cost turbine flow meter can be used for any application for measuring fluid or gas, and may be used in a service station environment for measuring fuel or vapor in vapor recovery applications.

摘要： The present invention provides an apparatus and method for accurately controlling the amount of NH.sub.3 to be applied to a field by measuring the NH.sub.3 flow rate without condensing or cooling the NH.sub.3. The system includes a control station 12 on the vehicle with a tachometer 12A or a GPS system for providing a vehicle speed signal to a control panel 13. The control panel includes a toggle switch 17 for adjusting the opening or closing of a valve 52 in the flow line to regulate the flow through the system, although the control panel alternatively may automatically control the valve 52. The vehicle transports a tank 20 containing liquid NH.sub.3 and a tool bar 30 for distributing the NH.sub.3 to the soil. After flowing through the flow meter 40, 60, 130, the NH.sub.3 is conducted to the soil through a series of hoses, fittings, a distributor, and tubing. The flow meter transmits a signal to the control panel, which is converted to a corrected flow rate signal in response to a fixed value vaporization correction factor. The temperature of the NH.sub.3 is also measured to correct for density variations. An improved variable area meter 60, 130 uses a hall effect sensor 72 and a magnet 68 mounted on a rotatable vane shaft 70 to overcome problems with prior flow meters. The improved meter 60, 130 is ideally suited for measuring the fluid flow of a low temperature vaporization liquid, such as anhydrous ammonia, propane and butane.

摘要： The present invention provides an improved flow sensor turbine assembly for fluid flow measurement. The flow sensor turbine is connected in fluid communication with a conduit through which a fluid whose flow rate is to be measured flows. The flow sensor turbine assembly includes a turbine, rotatably mounted on a turbine shaft, including turbine blades which rotate in response to the flow of fluid through the turbine assembly. Synthetic sapphire ball thrust bearings are provided adjacent to one or both ends of the turbine shaft to provide a low and consistent friction level and a high wear resistant bearing for the rotating turbine. Rotation of the turbine in the turbine assembly may be detected using an infrared rotation detector. Alternatively, a metallic insert may be positioned in one or more of the turbine blades. In such a case, rotation of the turbine may be detected using an inductive pick-up. The rate of flow through the turbine assembly is calculated from signals provided by the infrared or inductive pick-up rotation sensor in response to rotation of the turbine.
