Abstract

See full text

A fire suppression apparatus for mixing a first fluid, such as water, with a second fluid, such as foam, to be delivered through a fluid delivery line. A ratio controller is disposed within the delivery line and includes a first restriction area through which the first fluid passes, and that also accepts the second fluid. A fluid control mechanism is connected to the ratio controller, and includes a second restriction area. The fluid control mechanism delivers the second fluid to be mixed with the first fluid in the delivery line. A pressure sensing module measures the pressures of the first and second fluids. A control computer processes the pressures measured from the pressure sensing module, and maintains the pressure of the second fluid equal to the pressure from the first fluid. The first restriction area and the second restriction area define a ratio that determines a flow amount of the second fluid. The pressure sensing module may include two pressure transducers, a first pressure transducer to measure the pressure of the first fluid and a second pressure transducer to measure the pressure of the second fluid. The apparatus may be capable of drawing the second fluid a vertical distance of at least six feet from a second fluid source. The apparatus may be suitable for use with second fluids having a wide range of viscosities and desired relative flow amounts. The apparatus may be made in kit form, with the components thereof arranged together in modules for convenient assembly, transport, installation, and use.
