Since it is a replacement, all infrastructures are <br /> already in place. The new transducer has pressure ranges of 0- _ <br /> 30 feet of water as measured directly in gage pressure. The old co <br /> transducers had ranges of 0-120 feet of water as measured in <br /> atmospheric pressure corrected at the PLC. Please provide 0 <br /> hours and pricing to install the transducer and change the <br /> coefficient factors within the PLC and HMI software to correctly v <br /> 1. read the water level. The Allen Bradley PLC is a MicroLogix $ 1.280.00 N <br /> 1200. The new transducer is a Global Water WL300. The HMI <br /> software is WonderWare® 2000. Assume that there is already ti <br /> power in the box for the transducer. The new transducer will be <br /> located 225 feet below ground surface in an existing sounding <br /> tube. Assume the ladder logic is fully documented and that `0 <br /> manuals are available for all hardware. Assume all wells are C <br /> accessible by a standard automobile (four wheel drives are not ci <br /> required). <br /> L. <br /> Sample Job #2: The City has replaced a 3/4 Hp pump and 3/4 <br /> Hp VFD with a new 2.0 Hp pump and 2.0 Hp GS-2 AC VFD at a a <br /> groundwater extraction well. Please provide hours and pricing $_J 60.00- <br /> to install and program the new VFD. Assume the City has <br /> already installed the new pump. The old VFD is still in the well <br /> vault and needs to be replaced with the new VFD that the City <br /> 2. purchased (assume a straightforward physical installation). The .0�. <br /> new VFD also needs to be programmed. The Allen Bradley PLC <br /> is a MicroLogix 1200. Assume the ladder Logic is fully <br /> documented and that manuals are available for all hardware. <br /> Assume all wells are accessible by a standard automobile (four <br /> wheel drives are not required). <br /> I Packet Pg.48 I <br />
