Teledyne Isco offers a proprietary software system for data acqui- sition, storage, retrieval, and analysis. This software system, Flowlink, contains programs that allow 4200 series flow meters to store blocks of level and other data readings in the flow meter's memory. You retrieve this stored data with either a laptop computer or central computer connected to the flow meter by modem. You can use other programs in the package to process the retrieved data for further analysis. In addition to storing data, this software makes it possible to divide part of the flow meter's memory into partitions. These partitions may be for- matted in “rollover” or “slate” mode of data storage. You can also set up the flow meter to store data as a result of some sort of “triggering” event, such as level rising to a predetermined point, the passage of a predetermined time interval, or the occurrence of a storm event, such as rainfall.
Consult the Factory - A detailed explanation of the Flowlink software is beyond the scope of this manual. Information on Flowlink Software is available from its manual or from the factory.
