Abstract
A method and apparatus for delivery of a plurality of input fluids, at least two of which are liquids, in a foam delivery system, including a fluid controller having: a delivery mechanism for each fluid, at least one test parameter transducer for each fluid configured to measure a test parameter associated with each fluid, and a control system configured to receive the output of each test parameter transducer and to issue a termination signal configured to stop each of the delivery mechanisms if the measured parameter deviates from a preset range of values.
Claims43
A method of delivering foam insulation into a cavity, the foam being formed from a plurality of fluids, at least two of which are liquids,
- comprising the steps of:
- a) receiving each fluid into a fluid controller;
- b) forming a foam in a mixing chamber by combining the fluids received from the fluid controller;
- and
- c) delivering the formed foam into the cavity;
- d) measuring a test parameter for each fluid in the fluid controller;
- and
- e) stopping delivery of all fluids if the measured test parameter of any fluid falls outside of a preset allowed range of values for that fluid;
- wherein steps d) and e) are performed independently of an operator.
A foam delivery system for delivery of foam insulation into a cavity, comprising:
- a fluid controller configured to receive a plurality of fluids, at least two of which are liquids, and to measure a test parameter for each fluid;
- a mixing chamber configured to receive a plurality of fluids from the fluid controller and to mix the fluids to form a foam for installation into the cavity;
- and
- wherein the fluid controller is configured to stop delivery of all fluids to the mixing chamber if the measured test parameter of any fluid falls outside of a preset allowed range of values for that fluid.
A kit set of components for a fluid mixing system comprising:
- a mixing chamber and a fluid controller for delivery of a plurality of input fluids, at least two of which are liquids, including at least one delivery mechanism and at least one test parameter transducer for each fluid configured to measure a test parameter associated with each fluid, and a control system configured to receive the output of each test parameter transducer and to issue a termination signal configured to stop the one or more delivery mechanism if the measured parameter falls outside of a preset allowed range of values.
