Well Watch 660 DL

Add to Request

The Well Watch 600 Series is a line of sonic water level meters designed for semi-permanent installation. These units utilize sound waves and adaptive sensor technology to learn the makeup of a particular well allowing for the most accurate readings. The Well Watch meters were designed to be a solution for the long term monitoring needs of residential, environmental or production well owner/operators.


The Well Watch 660 DL includes a built-in display with keypad which allows the user to view real time data and to easily control the internal settings.  It also has a built-in data logger capable of logging up to 25 million time/date stamped data points. This is the perfect tool to monitor and trend water levels and usage. Utilize this data to prevent over use of a well and save yourself from a potential costly repair from a burned up pump. 


These units are easy to install in virtually any well setup. Each Well Watch unit comes with 3 MPT threaded nozzles, 1/2″, 3/4″ and 1″ in diameter. Simply choose the nozzle which fits into the vent hole on your well seal and screw the Well Watch tightly in place. Attachments can be used to angle the units for tight fitting spaces since the Well Watch does not need to be vertical to get a good reading. Then, choose from the multiple output options available to work with your application, including RS232, RS485 (Modbus), 4-20mA, 0-5V Analog, and USB (Well Watch 660 DL only). These are a perfect for monitoring remote wells or as a back up in case of a SCADA system crash. The Well Watch 600 series comes in a variety of options which are interchangeable to best fit the user’s application.


The optional Well Watch 310 Remote Display is compatible with any of the Well Watch models and can be mounted at a separate location, making it easy for the homeowner who wants to monitor their well levels and activity from inside their home. The display can be mounted wirelessly up to 300ft or through RS485 up to 3000ft away.


Well Watch 660 DL kit includes the Well Watch meter, 3 threaded nozzles (1/2″, 3/4″, 1″), A/C power adapter, USB cable, 8″ microphone extension tube and a quick start guide.
