Sensor spotlight: Decentlab's new DL-RAD
/Whether in open water, in a tank, or in retention basins — knowing the water level continuously and remotely is critical for operations and resource management.
Not every measuring point can be reached from below. A pump station, a stormwater overflow basin, a stream under a bridge — these are measured from above, without touching the medium.
That is what the DL-RAD | Radar Distance / Level Sensor for LoRaWAN® is built for. It measures distance and level using 80 GHz radar technology, with a beam angle of 8° and a resolution of 1 mm. Beyond level monitoring, it suits water treatment, bulk solids in silos. It is a generic and very robust ranging and proximity monitoring device.
Device and sensor head are connected by a 5 m cable. Power comes from two C alkaline batteries, data transmission runs over LoRaWAN®.
What sets it apart:
Measures from above: contactless 80 GHz radar — nothing is submerged, nothing touches the medium.
Focused beam: an 8° beam angle keeps the measurement on a narrow spot instead of spreading across the surroundings.
Resolves small changes: 1 mm resolution with a deviation of ≤ 2 mm, across a range of 0 … 20 m.
Long battery life: unattended operation on two C alkaline batteries, ideal for remote measurement sites.
Applications: Level monitoring · Water level monitoring · Flood monitoring · Pump stations and stormwater overflow basins · Water treatment · Bulk solids in silos · Generic ranging and proximity monitoring
