water leak control Applications

  • Flow & Energy Management Solutions for plant & machine

    Spire Metering offers several solutions for leakage detection. The flowmeters are used to monitor cooling water in machining process. They are used also in liquid process control and leakage detection applications.

  • Constant pressure pump control for variable demand irrigation

    Mist, Drip, Spray, or Big Guns, the Cycle Stop Valve (CSV) turns any Submersible, Turbine, or Centrifugal pump into a variable flow, constant pressure system. The CSV maintains a constant pressure on the irrigation system throughout a wide range of flow. Eliminating line breaks and leaks, while precisely applying an exact amount of water, the CSV can conserve water as well as energy.

  • Sewage Treatment Plants and Flow Sensors for Industry Application

    In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.

    Monitoring of hydroelectric dam sumps

    The Situation

    Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage:

    • The hydroelectric turbines are lubricated by lubrication oils.
    • The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils.
    • Vehicles including fork lifts, trucks, etc., can spill oils and fuels.

    Any accidental spillage of oil or grease or intentional wash down water containing minor amounts of oils, greases, and detergents must be collected and treated before discharge to the river. These fluids along with any water leaks are collected in sumps in the dam and are regularly pumped out. In many cases, the volume of water is substantial.
