Performance and/or Design Requirements (e.g. intended use, function or application, compatibility, requirements; reference to policy, rule, statute or other act of the Legislature, etc., as appropriate):

Equipment is needed for remote logging of hydrologic data to be telemetered to and accepted by Aquarius software for near real-time updates on field conditions. The XLink 500 logger provides multiple interfaces and protocols (HTTP, TCP/IP, FTP) for communication and three levels of security configuration. The SatLink 3 loggers transmit data using the GOES Satellite Network with an assigned and unique address. It is required that District data loggers can communicate using the LinkComm Software to be compatible with our current network. Both the XLink and SatLink units have sensor interfaces which allow connection to SDI-12, RS-232, USB host and device ports, and RS-485 devices which can be programmed using LinkComm software run on field laptop computers, tablets or cell phones. The data can be telemetered over the Verizon network with a removable SIM card or downloaded through Bluetooth connection while on site.

Intended Single Source:

OTT HydroMet

Estimated Dollar Amount:

$160,000

Justification for single source acquisition (what is necessary and unique about the product, service or source; steps taken to confirm unavailability of competition, as appropriate):

XLink 500 units have removable modems that can accept provisioned SIM cards and allows interchangeability between units. The units communicate using LinkComm software which allows continuity in programming with existing deployed equipment. The SatLink 3 units also use the LinkComm software for data download and programming. The EcoLog 1000 is able to accept a uniquely assigned Verizon SIM card which can be transferred between any EcoLog 1000 unit. The XLink, SatLink and EcoLog data loggers manufactured by OTT Hydromet are uniquely able to provide real time data to our network due to their compatibility with our Aquarius software.

Approved By (names & titles, as appropriate, e.g., requestor, requestor management, information systems, budget, purchasing):
