The Well Sounder 2010 PRO is a portable sonic water level meter designed to measure static water level in wells. The instrument uses sound waves to measure the distance from the top of the well to the water level, eliminating the need to lower anything into the well and preventing well contamination. Simply place the probe into a well cap vent opening and turn the unit on. Within seconds, the static water level measurement is displayed. With the press of a button, the instrument calculates and displays a variety of other information such as the total water in the well, rate of change, temperature, and battery voltage.

A built-in data logger can record up to 13,000 time stamped readings along with the well ID, temperature, and other associated measurements. The logger can be set to take measurements automatically at intervals between 1 and 60 minutes, or manually by pressing the log button on the keypad. The recorded data can be reviewed on the screen or downloaded to a computer for analysis using the serial RS-232 port or the included USB cable. Stored data is formatted in simple Windows-compatible text files sorted by well ID. Data can be easily copied from the instrument onto the computer and opened with almost any common program such as Word, Excel, or Notepad.

Other features of the Well Sounder 2010 PRO includes a power save mode which puts the unit to sleep between measurements when logging and turns the power off after a selected period of inactivity. If there are known defects in the well such as a rock fissure, simply set the measurement range minimum and maximum to ignore the interference. The multi-purpose bi-directional serial port can also be used to transmit data in real-time to a remote readout or logging device.

Eno Scientific Well Sounder 2010 PRO Water Level Meter Reviews

The Eno Scientific Well Sounder was not nearly as reliable as I thought it would be. Too costly and inaccurate for what I was looking for.

Submitted by

Well Sounder 2010 PRO
I found this water level meter to be extremely easy to use and very accurate. My well has a rather low recovery rate, in the order of 0.2 gal per min so it is important for me to know the water level in the well. The logging feature allows me to monitor various activities that use water and determine the recovery time for each.

We have owned our well sounder 2010 for over 3 years now. We own a well business in AZ and have found this product to be very unreliable when it comes to finding the static level or pumping level on unknown wells. In AZ, the water levels have been dropping dramatically and water in most wells is dropping below the first set of casing perforations which we finally got the owner of the well sounder 2010 to admit to us that the signal gets lost in. If you can measure the static when the Pump is removed and then use the well sounder after the pump is re installed to follow the draw down, you can finagle it to somewhat find the water level. So it is not the answer as advertised and has proven to us that you still can't trust what it says. We won't anyways.

Questions & Answers

| Ask a Question
Is the well sounder waterproof?
The sonic water level meter unit and probe are resistant to rain and splashing but not saturation or submersion. They will be damaged if submerged.
How deep will the Eno Scientific well sounder measure?
The maximum range is 2000 feet. On a 6" well with tight clean casing all the way down and little to no obstructions along the way, the maximum depth can be achieved. On uncased wells drilled through porous stone or with irregular walls, or any obstructions such as spacer rings or couplings, the range will be reduced.
What happens when the log memory is full?
When the log memory is full, the sounder stops recording new data and preserves the first data points. The Well Sounder 2010P will continue to record data in its extended data memory up to 2GB and be accessible with the USB connection.
Can the Well Sounder be used on hand dug wells?
Hand dug wells are often fairly large and irregular, which may cause multiple or weak sound reflections. However, in any difficult to measure well, a small tube can be installed specifically for measurement. A 3/4" PE pipe can be used for up to 1000 feet provided splicers do not restrict the ID.
Can I use the Well Sounder on an open well?
The Eno Scientific Well Sounder was designed to work on a closed well. A simple piece of rigid card board or plastic held against the opening is enough to meet this requirement. In many cases it will work on the open well but may be off by a couple feet.
Can I use an external power source?
Yes, the sonic water level meter can be used with six AA alkaline batteries or with a 6.5-12 VDC external power source. If using an external source, the power must not exceed 16 VDC.

Eno Scientific Well Sounder: The power of sound echoes water level measurements

Measuring the distance to the water’s surface in a well can be difficult, especially when the well is deep and full of obstacles that can block and entangle mechanical measuring tools. But the  Eno Scientific Well Sounder 2010 Pro gets around those obstacles with the power of sound, eliminating the need for any mechanical measuring. The device sends low-frequency sound waves down a well until they hit liquid. “The sound can go around all the wiring and pipes and stabilizers within the well and give a measurement within a second,” said Rachel Bean, Eno Scientific sales manager. The Well Sounder’s probe emits broadcasts low-frequency sound waves from the top of a well. The waves return in about one second per 500 feet.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.

Parasite Behind Yellowstone River Fish Kill Found In Other Rivers

A parasite that caused a massive fish kill in Montana’s Yellowstone River has been found in at least seven other rivers in the state, according to the Bozeman Daily Chronicle . Scientists with the Montana Fish, Wildlife and Parks department made the find. So far, the parasite has been confirmed in the upper and lower Madison, East Gallatin, Bighorn, Stillwater, and Boulder Rivers. It had already been confirmed in the Jefferson and Shields Rivers. The microscopic parasite causes proliferative kidney disease, one of the most serious diseases to impact whitefish and trout. The effect of the disease on Yellowstone’s fish populations is exacerbated by other stressors like near-record low flows, consistent high temperatures and the disturbance caused by recreational activities.
