As observed, its modular construction and relative bulk are expected to disadvantage its field application. The communication package also requires upgrading as this will pose some difficulty with users who are unfamiliar witt: the menu system. for liii) this Nindata Pressure Transducers. Service equipment have involved complete requirements rebuild and replacement of parts and retesting under laboratory conditions. While Mindata are capable of performing a large part of this function, there is a major dependability on parts imported from the united states. In some cases, the delay period of orde'~s or redundant period of equipment has been up to 6 months. The ini tia 1 unvented transducers purchased are no lcnger supp:.ied nor serviced, and only the replacement with a vented item can be offered. Liv) Flowl'1eter. The transducer is common amongst devices for monitoring water levels and storage in local reticulation systems. A local agent for Kent Instruments exists. A "lookup" tabj.e for the current combination of oriface plates and discharge i:ubes should be developed. At this stage, these figures are best presented in tabular form since calibration corrections may be effected easily. In the long term, mathematical relationships describing the "rating curves" for each configuration should be developed. Lv) Barometric Transducer. Comments as per Mindata Pressure transducer. Three hourly barometric data is available from the Bureau of r,reteorology for specific sites. Depending on the accuracy requirements interpolated of barometric correction in water levels, an data set based on this data could be utilised in the long term.
