The scope primarily concerns radar level sensors for measuring water levels in sewer pipe networks and stormwater applications. In addition to level sensors, we are also looking for tilt sensors. The procurement covers six sensor types: • Sensor 1: Level, LoRaWAN, internal antenna • Sensor 2: Level, LoRaWAN, external antenna • Sensor 3: Level, NB-IoT/LTE, MQTTS • Sensor 4: Level, NB-IoT/LTE, Cloud API • Sensor 5: Tilt sensor, LoRaWAN • Sensor 6: Tilt sensor, NB-IoT/LTE, Cloud API Each sensor type is described in a separate appendix, which includes the requirements, evaluation criteria and pricing information. Tenderers may submit tenders for one or more sensor types, depending on which products they offer that fulfil the requirements.
