tNCEA – National Hydrometry Data Logger

Description

This procurement requirement is divided into Lots: Lot 1 – This lot is designed to meet the EA requirement for a robust (desired minimum IP66 rating) logger device to operate at the majority of river level, river flow and rainfall sites as backup devices to the main existing remote telemetry units. Compact logger device, desirable maximum device dimensions of 200mm x 150mm x 80mm, should allow fitment to new and existing enclosures. Where device has telemetry functionality inclusion of a multi band modem is desirable. Lot 2 – This lot is designed to meet the EA requirement for a robust self-contained single sensor (desired minimum IP67 rating) logger device to operate in specific use cases where space may be limited. Dimensions of device should allow fitment within tube diameters ≥50mm. Device should provide functionality to directly connect input sensors, without need for external junction box, to logger whilst maintaining IP rating. Logger device must be compatible with sensors on the EAs existing pressure transmitter framework. Where device has telemetry functionality inclusion of a multi band modem is desirable. Where data loggers have telemetry functionality, they are required to operate with Schneider telemetry systems using either DNP3, WITS DNP3 or Lucid (when available). Bidders may apply for one or both Lots.
