Apparatus for deploying equipment in a fluid container or fluid conduit comprises a fluid housing having an outlet aperture, the fluid housing being adapted to be secured to the container or conduit such that the outlet aperture is in fluid communication with an aperture in the container or conduit. The valves reduce the flow rate when the temperature of the water is at or above the predetermined level. The SMCI monopulse curves are calculated in advance for the expected beam steers. A robustness criterion, by analogy with self-assembled physical systems, is applied to select the best, most robust, clustering.
