Delta Lugeon Test set DESCRIPTION: Delta Lugeon Test set is a water pressure test that calculates lugeon units of water test . It consists of an electronic computer with LCD readout, digital transducers for pressure and flow of water and a keypad for entering hole depth and time of test – test number – hole number. The way the test is done is after the hole is drilled and the suitable packer (not supplied) is inserted; the water pump outlet that supplies water (not included) is connected to the inlet of the transducer set and the outlet of the transducer set is connected to the hole entrance. The necessary inputs such as test duration, hole depth etc are input to the instrument with the keypad. The pump is started and the test button on the instrument is pressed. The instrument records the pressure, averages it during the test and records the total volume of water that goes into the hole and after the test calculates and retrns the lugeon value. A detailed description of Lugeon Test follows on the next page.
Volume / Pressure Transducer Unit :
Turbine flow meter 0-150 lpm Pressure transducer 0-20 bars ps: other ratings possible upon request
