Technical Report WRD92039 Viewed at 15:07:17 on 29/07/2010 Page 14 of 192. 2. EQUIPMENT ~rRIALLED 2.1 General The basic suite of equipment required to establish a system of logging test pumping and remote site water level data was identified as a part of a commission involving the Australian Centre for Tropical Freshwater Research. The hardw~I'e options are presented in "Hardware Options for Pump Test Da.ta JI.cquisition" (Reference 3). The test pumping suite is based on a central logging system (unvented) which is required to service logging functions in proximity to the test bore. This includes pumped bore drawdown, discharge rate, barometric pressure and drawdown in a single "close" observation bore. The vented system was not preferred due to the potential for damage (both downhole and above ground) and handling factors, its performance und,,,r variable thermal conditions, the variability in venting characteristics (ie. efficiency) of available equipment and the potential for water ingression in humid conditions. The remote site logging requirement was proposed to be met by a single channel vented system. Below is a general description of the equipment trialled during this project. Figure 2. indicates the relative positioning of the componentry within the data acquisition system. Their specifications are included in Appendix B. 2 2 Logger;s l1indata Logger The unit trial led is a series 3500 Logger (see Plate 1). It will accept periodic signals from up to four analogue and two diqital inputs, convert the data to user specified units, and record this data with corresponding time and date to a minimun resolut:ion claimed to be one second.
