Provided is a cleanable conductivity sensor and related methods having a distal sensing end in which active sensing elements are positioned and an outer fin specially configured to minimize unwanted interference without impacting the ability for automated cleaning of the distal sensing end. A rotatable wiper or brush may be periodically rotated over the distal sensing end, thereby removing unwanted biological build-up and avoiding fouling, thereby increasing the sensor deployment time without active intervention and maintenance.

Cleanable flat-faced conductivity sensor

Provided are multi-parameter sonde systems having a unique integrated user interface for ease of set-up and control, service and maintenance, even in the field and without accessory controllers. The necessary components, such as central processing unit, display and accelerometer are positioned in a water-tight housing, with the display configured for convenient observability and readability. A plurality of sensors provide electronic signals to the CPU, such as by a measurement subsystem. Upon a controlled change in orientation or a force application to the sonde, the display via the accelerometer provides a desired output display configuration.

Integrated user interface for status and control of a submersible multi-parameter sonde

Provided are multi-parameter sonde systems having a unique form-factor, wherein the plurality of sensors are arranged in a tight-fit configuration. This provides a single distal sensing surface and minimal separation distance between adjacent sensors. The sensors may be pie shaped with an interlocking feature to tightly hold the sensors together, with a sensor guard disposed over the outer surface of the interlocked sensors. Sensor-guards disclosed herein may have an integrated sensor storage and sensor guard configuration, thereby avoiding a need for a separate storage cup and that are configured to minimize unwanted biological growth. Also provided are uniquely shaped individual sensors having interlocking features to hold several sensors together in a sonde.

Reversible sensor guard for use with a sonde

Provided herein are sondes having a pressure sensor that is separated from active sensing portions of the other sonde sensor or sensors by a longitudinal distance along the sonde. The pressure sensor may be positioned in the base portion of the sonde, with removable sensors connected thereto with a sensor plane at a distal end of the sensors that measures any number of parameters associated with the liquid in which the sonde is immersed. An orientation sensor positioned in the base portion determines an orientation angle of the sonde that, in combination with the depth determined at the pressure sensor location by the pressure sensor, provides the ability to determine the actual depth of the sensor plane, irrespective of orientation angle. Accordingly, improved depth measurement is achieved, without having to confine placement of the pressure sensor at the sensor plane.

Submersible multi-parameter sonde having a high sensor form factor sensor

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 for 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.

Submersible probe apparatus for aqueous environment monitoring with new cam-twist interconnect, liquid barrier, and battery pack

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. An A/D module also communicates with the control module and is used to convert data from a selected well into digital form for use by the computer. Input modules interface between the probes and the A/D module to provide a compatible input to the A/D module.
