Envco – Environmental Equipment

FEATURES:
• Display – 2x16 character LCD
• Temperature compensation – in probe
• Alarms – high and low 10 to 700 ft.
• Serial port output
• Acoustic probe
• Temperature sensor input

The Well Watch transmits an acoustic pulse into the pipe, then measures the time to the returned echo. The distance is calculated as the product of the sound speed and the time. Since the sound speed has a large temperature dependence, a temperature sensor is included in the probe to adjust for variations.

Benefits:
o Rugged weather resistant PVC data unit | Designed for field installation
o Separate data unit and sensor probe | Requires minimal installation time and effort
o Data unit conveniently attaches near well | Allows easy access to the data unit
o No water contamination
o Auto temperature compensation
o Easy to view depth, temperature, battery condition, diagnostic codes and programming interface
o Easy to find key data and programming specifications
o Programmable data logging
o Over 14,000 data points stored in non-volatile memory
o Accurate date/time stamp for all data points collected
o Ability to easily download data for analysis or connect to remote readout device
o Powered by standard AC adapter or optional external battery pack
o Power saver mode | Extends battery life

The product consists of a control unit and a probe. The control unit contains the driver electronics, processor, display, and keypad. Internal non-volatile memory is included to record system settings, calibration data, and log up to 14,976 data points. A real-time clock/calendar is also included to time stamp the recorded log data. The RS232 port can be set to output data to a remote device or used as a bidirectional communications interface to a computer for remote programming or data download. A power jack allows the unit to be run from an optional AC adapter or battery pack.

The probe contains a speaker, a microphone and temperature sensor in the probe tip. The probe is designed to easily attach to a standard well cap vent opening while also allowing the display unit to be operated in a convenient location up to 6 feet away.
