Abstract

A modular control, provided for sensing characteristics of a fluid and controlling the dispensing of additives into said fluid, is contained in a box-like housing (22) having an openable wall (34) which is sealable to a remainder of said housing in a water-tight manner. A plurality of printed circuit boards (74, 76) can be mounted in an interior of said housing. A display (66) is mounted on one of the housing walls.
An input device (70) for inputting data and control commands is mounted on one of the housing walls. A user can select particular probes (102), signal conditioning boards (104), output control boards (116) and output devices (122) to sense one or more fluid characteristics (150) and control additive dispensers (122) to control the sensed characteristics (164).
