NVE runs a network of nearly 1000 hydrometrical monitoring stations. Most of these stations use two submersible pressure sensors with SDI-12 interface, measuring water level and where applicable, water temperature.
NVE is to enter a frame agreement with a supplier for submersible level transmitters. The transmitter NVE is looking for is a standard, digital submersible levels transducer with SDI-12 interface, without internal logging and without batteries installed .
NVE estimates that 25–50 above-mentioned sensors will be purchased per year.
Normally, NVE purchases sensors in batches of 25. NVE would prefer to sign a framework agreement with one supplier for the product. NVE estimates that the total value of the purchase will be NOK 3.400.000 for 400 sensors during the contract period.
