Global Water’s WL650 Sonic Water Level Meter is a self-contained, battery-operated meter that uses sound waves to measure well water level. Fast, accurate measurements are possible in the field or anywhere without the use of down-hole water level meters. The Sonic Water Level Meters are lightweight, compact, versatile, and easy to operate.

The meter is simple to operate. Select either the NORMAL (10-500 feet) or DEEP (200 to 1500 feet) setting on the DEPTH switch. Then to measure a capped well, simply insert the duct into the access port and push the power-on switch. In a few seconds the water level will appear on the digital display. In the NORMAL setting, the sonic sounder stays activated for 5 seconds or 5 pings. Using the DEEP mode the level sounder emits 4 pings in 16 seconds. For more measuring time, hold the switch down as long as necessary.

Key Features:

• Fast accurate water level measurements in seconds
• Avoid cross contamination
• No equipment to clean
• Gain/Sensitivity option
• Works in cased steel or PVC capped wells, partially cased rock wells, crooked wells and wells with pipes, wiring and operating pumps.

For uncapped wells, use the provided cover plate. It slips onto the measuring duct and provides a seal for up to 6 inch diameter casings. Cover plates for larger diameters can be easily fabricated from plastic or metal sheet.
