    SATURO 1. INTRODUCTION Thank you for choosing the SATURO Infiltrometer from METER Group. This manual should help you understand the functionality of SATURO, make high-quality measurements, and get the most out of the instrument. SATURO was designed to be an automated instrument for measuring permeability and field saturated hydraulic conductivity ( ) in soil.

  • Page 6: Operation

    OpERATION 2. OpERATION Please read all instructions before operating the SATURO to ensure it performs to its full potential. 2.1 INSTALLATION Follow the steps listed in Table 1 to set up the instrument. Table 1 Installation Verify Access to Water Identify a source of water on site or bring water to the site.

  • Page 7: Functionality

    SATURO Table 1 Installation (continued) Connect the hoses and sensor cable to the designated fittings on the infiltrometer head. Each input and output line is purposefully a different size of tubing to help prevent a mismatch. If a tube does not snugly fit into a connection, it is probably in the wrong one.

  • Page 9 SATURO reduce water usage. Table 2 provides rough guidelines to determine initial pressure head settings. These values are starting points only and should be adjusted for the particular soil based on experience. b. Set soak time. During soak time, the infiltrometer applies water to achieve saturation of the soil before beginning the pressure cycles.

  • Page 24 (∝). This analysis is known as the two-ponding head approach (Reynolds and Elrick 1990). The two -ponding head approach is the technique used by SATURO, though with some modifications and simplifications. The easiest equation for this calculation is from Nimmo et al.
  • Page 25 ∆ is the infiltrometer insertion depth and is the infiltrometer radius. For the SATURO ∆ 5-cm insertion ring, = 5 cm and = 7.5 cm, so = 9.3 cm.
  • Page 26 SYSTEM The hydraulic conductivity is then multiplied by the difference in quasi-steady state infiltration rate for the last pressure cycle and divided by the difference in the measured pressure head from the last pressure cycle. Equation 4 is equivalent to Equation 41 from Reynolds and Elrick (1990) and removes the λ...

    SATURO 4. SERVICE This section describes the calibration and maintenance of the SATURO infiltrometer. Troubleshooting solutions and customer service information are also provided. 4.1 CALIBRATION The water pump comes factory calibrated and is accurate to within ±5% of the reading at the time of shipment.
  • Page 28 Adjust Measured Value screen (Figure 35). Enter the new value from the scale or cylinder reading, and select Done. This value becomes the new default water flow value (Figure 36). SATURO uses this flow value to measure the flow of water into the infiltrometer head.

  • Page 29: Maintenance

    The water pump on the SATURO is a peristaltic pump with a replaceable cartridge that houses the tube and rollers. The tubing and rollers can wear out over time, typically around 5,000 hours of run time. The pump run time is tracked in the diagnostics screen of SATURO.

    SATURO is powered by 12-V, 7-A sealed lead acid battery. Over time, there will be a decrease in the maximum charge value of the battery. If the battery does not come up to full capacity after a full charge (typically 4–6 h), it will need to be replaced. Contact Customer Support information for a new battery and servicing.
