How Do Interface Meters Work?

Simply, the meters provide two different signals depending on if they are in product or a fluid like water that is conductive.

To detect liquids, Solinst® Interface Meters use an infra-red beam and detector. When the probe enters a liquid the beam is refracted away from the detector and an audible tone and light is emitted.

If the liquid is non-conductive (as is the case with LNAPL and DNAPL) a steady tone and light signal the presence of product. If the fluid is conductive (water) , a conductivity circuit is completed. This overrides the infra-red circuit, and the tone and light are intermittent.

Operating Principles

Product (Non-Conductive Liquid) = Steady Light & Tone

Water (Conductive Liquid) = Intermittent Light & Tone

When should you use the Model 104 Sonic Water Level Meter to measure depth to water in a well versus a standard water level meter or datalogger?

• In crooked or obstructed wells where equipment can potentially be entangled

• At contaminated sites (concerns of cross contamination from well to well and decontamination of equipment)

• Use when fast manual single point data collection is required

• Ideal for use in narrow, cascading, or difficult to access water level wells

How accurate is the Model 104 Sonic Water Level Meter and how long does it take to collect a reading?

In ideal situations, it can be accurate to 3 cm (0.1 ft) and takes approximately 1-4 seconds to provide a reading dependent on depth to water. When increased accuracy is required, the control unit can be used to enter site specific well details (measurement parameters) such as:

• Drop tube diameter

• Min/max water level measurement

• Water temperature

• Offset of probe from ground level

For well openings greater than 1" diameter, the plastic disc should be used to cover the well opening. Sealing off the top of the well facilitates a strong signal (pulse is an air pressure /low frequency sound wave) that provides greater accuracy and prevents external interferences from affecting the reading.

How does it work?

The Sonic Water Level Meter works by the Probe transmitting a sound wave into the pipe or well and measuring the time it takes for the pulse to return after making contact with water. The distance to water is calculated using the speed of sound and time. Since the speed of sound varies with temperature, a temperature sensor is located in the probe to adjust for variations. To account for different well diameters, offsets, well obstructions or features, the Control Unit allows you to input measurement parameters to get the most accurate water level reading possible.

No Contact With Water Surface Required!

Need Help Selecting The Right Solinst® Levelogger® 5?

1. What is the anticipated change in water level?

Leveloggers® should be placed deep enough below the surface of the water to remain submerged. This maximum submergence is then used to select the appropriate range of Levelogger®. (M5/F15 = 5 meters/15 feet)

2. Will data be collected for a day or longer?

Data collection needed for minutes to hours:

• Although we always suggest compensating for barometric pressure changes, you could assume minimal change in atmospheric pressure, so a Barologger may not be required Data required for multiple days:

• To maintain accuracy , use a Barologger 5 to correct for atmospheric change - PT#114608 (One Barologger can be used to compensate all Leveloggers® in a 20 mile (30 kilometer) radius and/or with every 1000 feet (300 meter) change in elevation.)

3. Do you want to communicate and view data with the Levelogger® downhole?

If yes, you need a Levelogger® 5 App Interface (SO-115009) or PC Interface Cable (SO-109609). Choose Direct Read Cable (DRC) specify lengths (including shorter length for Barologger, if required).

If no, you need either a Desktop Reader 5 (SO-114404) or Field Reader 5 (SO-114403). Choose suspension stainless steel wireline or Kevlar cord.

4. What length of wireline/cord or Direct Read Cable do you need?

You need to add the anticipated change in water level to the static water level (depth to water from ground surface).

Stainless steel wireline or Kevlar cord assemblies are available to 500 ft.

Direct Read Cables are available up to 1500 ft, specify lengths:

• 5 ft – 500 ft (at 5 ft increments)

• 510 ft – 1000 ft (at 10 ft increments)

• 1050 ft – 1500 ft (at 50 increments)

5. How do you want to communicate with your Levelogger® 5?

Remove from monitoring location and use a laptop or computer and PC Software:

• You will need either a Desktop Reader 5 (SO-114404) or a Field Reader 5 (SO-114403)

Levelogger® 5 remains on site, installed on a *DRC (or use a Direct Read to Optical Adaptor)
