Abstract: A fluid flow transducer module includes a fluid flow conduit having an inlet for receiving fluid, a transducer for measuring rate of flow of the fluid, an interface in communication with the transducer and adapted to receive rate of flow measurements from the transducer, the conduit having an outlet for flowing the fluid from the transducer to a reservoir, the outlet extending transversely of the conduit, a housing for the conduit, conduit inlet, conduit outlet, and transducer, the housing having opposed first and second walls, each wall having an opening for the outlet therein, and at least one of the walls being adapted for stacking engagement with a second transducer module of a same structure, such that the outlets of the modules are aligned to form a common conduit, and the interconnected modules form a flow transducer assembly having a plurality of fluid flow conduits and transducers.

Abstract: A temperature and humidity control system for natatoriums. The system provides a constant volume of air circulation which is used to control temperature and humidity in the natatorium while inhibiting the accumulation of moisture on the surfaces defining the natatorium. Usually, ambient air is introduced into the system and moisture latent air discharged from the system under controlled conditions. When the humidity of the ambient air is too great the system operates in a self-contained cycle. Return air from the natatorium flowing through the system is treated to maximize its relative humidity. Subsequently, it flows across a cooling coil. This cooled air flows through a heat exchange module where it is placed in exchange relationship with the air being drawn from the natatorium. It cools the air drawn from the natatorium to maximize its relative humidity and this air in turn flows across the refrigeration coil removing substantial quantities of moisture.
