IN12-W: Turf-Tec Mariotte Tubes
New - Turf-Tec Mariotte Tubes are both connected outside the test area for ease of reading!
Mariotte Tubes have calibrated site glasses and ring on site glass to allow ease of measuring with new site glass sliding indicator
|The new Turf-Tec Mariotte Tubes match the ASTM standard for testing of soils with a hydraulic conductivity between 1X10-2 cm/s or less than about 1 X 10-6 cm/s or sand type soils with high infiltration rates.
These tubes are a companion tool for use with the Turf-Tec 12 and 24 inch Infiltration Rings (IN10-W). They match the ASTM Standard D 3385-03 which replaced old ASTM Standard D 3385-94.
The Turf-Tec Mariotte Tubes are constructed of durable heavy wall PVC tubing with solid brass and stainless steel hardware for many years of service.The Turf-Tec Mariotte Tubes allow for measurement of liquid flow during the infiltration test by providing a constant flow of water into the Turf-Tec 12 and 24 inch Infiltration Rings. Without the tubes, a technician needs to constantly fill the Infiltration Rings with a graduated cylinder in order to maintain the fluid level and constant head pressure. With the Turf-Tec Mariotte Tubes, the tubes allow the water that is infiltrated into the soil to be replenished through the tubes, keeping the head pressure constant eliminating the need for an extra technician during the test procedure. Infiltration amounts are simply read on the site glass at selected time intervals.
The set consists of two Mariotte Tubes, one holding 3000 ml and one holding 10,000 ml. Each tube draws a vacuum and regulates the flow of water from the Mariotte tube and into the Turf-Tec 12 and 24 inch Infiltration Rings. Once the flow rate of liquid from the Mariotte Tubes is consistent with the infiltration into the soil from the Turf-Tec 12 and 24 inch Infiltration Rings, the calibrated sight glass on the side of the tubes is checked at given time intervals for infiltration rates. The Turf-Tec Mariotte Tubes allows testing personnel the ability to perform other tasks and periodically check and record the infiltration rate instead of constantly filling the Infiltration rings by hand as the head falls.
The new design allows both Turf-Tec Mariotte tubes to be connected to the outside if the IN10-W Turf-Tec 12 and 24 inch Infiltration Rings to facilitate reading of the site glass. No more looking inside the annular space between the tings for the readings!
This method of testing is useful for field measurement of the infiltration rate of soils. Infiltration rates have applications in the field of liquid waste disposal, evaluation of potential septic tank disposal fields, leaching studies and drainage efficiencies. They are also helpful in determining irrigation requirements, water spreading or recharge, canal leakage and reservoir leakage testing and studies. The purpose of the double ring is to insure the downward flow of movement of water to insure proper measurements. These infiltration rings are ideal for taking ASTM infiltration tests on all areas and match the ASTM 3385 test. They are used by Professional Engineers (P.E.) worldwide.
The tops of the Turf-Tec Mariotte tubes are sealed to allow you to achieve a constant head of water inside the Infiltration rings in relation to the height of the Mariotte tubes.
