INW LEVELSCOUT INSTRUCTIONS Introduction What is the LevelSCOUT? The INW LevelSCOUT Smart Sensor is an integrated datalogger and level/temperature sensor and is ideal for site assessments, tidal studies, environmental monitoring, surface water discharge measurement, and aquifer level monitoring, as well as aquifer storage and recovery.
TABLE OF CONTENTS INW LEVELSCOUT INSTRUCTIONS How Pressure/Level Sensors Work Liquids and gasses do not retain a fixed shape. Both have the ability to flow and are often referred to as fluids. One fundamental law for a fluid is that the fluid exerts an equal pressure in all directions at a given level.
INSTALLATION AND OPERATION INW LEVELSCOUT INSTRUCTIONS Installation and Operation Power The LevelSCOUT comes with a 1/2 AA 3.6v lithium battery. Connecting the LevelSCOUT to a Computer In its cabled configuration, the sensor cable is terminated with a weather-resistant connector. In its cableless configuration, the sensor is terminated with a weather- resistant connector inside a screw-cap.
INSTALLATION AND OPERATION INW LEVELSCOUT INSTRUCTIONS Installing the Sensor The LevelSCOUT measures level. The most common application is measuring liquid levels in wells and tanks. In order to do this, the sensor must be installed below the water level at a fixed depth. The installation depth depends on the range of the sensor.

MAINTENANCE INW LEVELSCOUT INSTRUCTIONS Maintenance Changing Batteries The LevelSCOUT is powered by a single 1/2 AA 3.6 lithium battery. In most situations the battery will last for years. If you need to replace the battery, contact INW for information on getting it replaced. You cannot simply replace the battery itself but must replace the entire compartment.
MAINTENANCE INW LEVELSCOUT INSTRUCTIONS Miscellaneous Sensor: There are no user-serviceable parts, other than the batteries. If problems develop with sensor stability or accuracy, contact INW. If the sensor has been exposed to hazardous materials, do not return it without notification and authorization.
TROUBLESHOOTING INW LEVELSCOUT INSTRUCTIONS Troubleshooting Erratic Readings Erratic readings can be caused by a poor connection, damaged cable, moisture in the unit, or a damaged transmitter. In most cases, erratic readings are due to moisture getting into the system. The first thing to check is the connection. Look for moisture between contacts or a loose or broken wire.
INW LEVELSCOUT INSTRUCTIONS Appendix A: Technical Specifications General Specification The INW LevelSCOUT is a microprocessor based digital intelligent sensor designed to measure and record level, temperature, and time, utilizing state-of-the-art low power, battery operated circuitry. Level is measured with an extremely rugged and stable piezo-electric media-isolated pressure element combined with an analog-to-digital converter.
SETTINGS AND CALIBRATION INW LEVELSCOUT INSTRUCTIONS Appendix B: Settings and Calibration Settings and calibration values can only be changed when there is no data on the sensor. Be sure to retrieve any data and then erase the data on the sensor before proceeding.

SETTINGS AND CALIBRATION INW LEVELSCOUT INSTRUCTIONS Submergence One-Point Calibration: -- Computing Offset -- • Place sensor in the fluid you are measuring at a precise known level. • In the Ref box for the first point, enter this level or pressure.
SETTINGS AND CALIBRATION INW LEVELSCOUT INSTRUCTIONS Depth-to-Water When using the Depth-to-Water setting, you may want to change the channel label at the top of the Settings window to read “Depth” or “Depth-to-Water”. NOTE: Be sure to use the same units for all measurements in this calculation. For example, if you have the program set to display in Ft H2O then be sure to enter the barometric pressure and depth-to-water readings in Ft H2O.
SETTINGS AND CALIBRATION INW LEVELSCOUT INSTRUCTIONS Elevation Above Sea Level When using the Elevation setting, you may want to change the channel label at the top of the Settings window to read “Elevation”. NOTE: Be sure to use the same units for all measurements on this page. For example, if you have the program set to display in Ft H2O then be sure to enter the elevation, barometric pressure, and depth-to-water in Ft H2O.
SETTINGS AND CALIBRATION INW LEVELSCOUT INSTRUCTIONS Staff Gauge When using the Staff Gauge setting, you may want to change the channel label at the top of the Settings window to read “Staff Gauge”. NOTE: Be sure to use the same units for all measurements on this page. For example, if you have the program set to display in Ft H2O then be sure to enter the barometric pressure and staff gauge readings in Ft H2O.
ALTERNATE CONNECTION OPTIONS INW LEVELSCOUT INSTRUCTIONS Appendix C: Alternate Connection Options INW recommends connecting the sensor to your computer using the INW USB cable. However, when using Aqua4Plus, the sensor can also be connected using an RS232 serial port or a USB-to-Serial cable, as described below. (Note: Aqua4Plus Lite can only communicate using the INW USB cable.)
