Abstract: A submersible water monitoring probe assembly including: a cam-twist type interconnect mechanism; flexible PCBA (printed circuit board assembly) having flexible ribbon cable sandwiched between layers of an elongated circuit board, the ribbon cable extending outwardly from each end of the board and along an elongated probe-body; internal gas-permeable and generally liquid impermeable barrier assembly disposed within the cam-twist inter-connect mechanism between the elongated PCBA housed within the probe-body and an electrical connector of the cam-twist interconnect mechanism; and if used, a vented cable assembly, or other means of transmitting sensor data collected by sensing circuitry within a submersed probe-end. Also, an extender assembly (or use with the submersible probe. At each end portion of the extender assembly is either a male cam-twist type interconnect piece or a female cam-twist type interconnect piece. The length-extender assembly may be electrically adapted to house one or more battery cells.

Abstract: An apparatus is provided for gathering monitored data from one or more selected wells of a number of wells and reducing the monitored data in a real time manner to a useful form for analysis by one skilled in ground water evaluation. The apparatus can also be used to control the discharge rate of well water to further assist in the analysis of the characteristics of the selected wells. The apparatus is an integrated system which includes a computer, a number of inter-communicating modules, probes inserted in the wells for sensing water level, and a flow meter for use in measuring water flow rate. A control module directly interfaces with the computer and controls the sending of control and data information to and from the computer. A pump/flow module communicates with the control module and is used in controlling the discharge rate of water from a selected well operatively joined to a pump.
