GOJ333 r ! The 590V comes with a battery that is located inside the instrument housing system that is capable of operating for 6 months with uninterrupted use. Another advantage for specifying the HANDAR synthesized radio is the ability to adjust the output. It is believed that 50 to 75% of your sites could achieve data transmission at a much lower output wattage. HANDAR's radio is adjustable for output wattage and the lower the output the longer the life of the battery. HANDAR is the only company that offers a low battery warning which is transmitted with the data to your central system so that maintenance can be planned for, not guessed at. The 6 stream gauges that are specified for your flood warning system can be accomplished by three methods. First, utilizing stilling wells which would incorporate HANDAR's model 436 incremental Shaft Encoder. If stilling wells are the preferred method for stream gauge measurements HANDAR would propose to supply the floats and incremental shaft encoder with cabling. The second method of measuring flood height is with an acoustical sensor. The physical placement of the sensor is the limiting factor in using this measure~ ment technology and usually requires a bridge for the placement. HANDAR has the capability of supplying acoustical sensors if so desired. The third method is the utilization of pressure sensors. The HANDAR 585B pressure measurement system is included in our quotation to meet your require- ment. -wi Our quotation includes 150' of cabling because the location of the electronics at each site was not specified. Also not specified was the protection required for the pressure sensors when a flood is occuring. Because of the silt, debris, and very rapid movement of water (that typically occurs in a Colorado River flood), the utilization of pressure sensors and the protection of the sensors will have to be explored in detail. In any event, whichever of the three methods are chosen HANDAR instrumentation with associated sensors will meet or exceed your measurement requirement. I I i : .~ The base stations specified are configured to include the model 548SV receiver/decoder connected to a IBM compatible micro computer and that combi- nation has the capability of processing the remote transmitted data in a real time format. Also included is our model 600-0743 power supply to meet your uninterrupted power supply requirements. The alert software package that HANDAR will furnish is that which is specified in the systems description. Alert software is a QNX based software package that competitive software in three key areas. a superior product to HANDAR model 547-5005 is superior to the User friendliness, superior color graphics modeling, and macros used for many different forms of data retrieval and data reduction. HANDAR would be more than pleased to demonstrate the full alert software package.
