The BD2-P is the permanent version of our ever popular BD1 system. All components are mounted in a slimline steel pillar that would look at home on any street, path or river bank. Measuring just 300mm wide and 770mm high, coming in a range of colours and lock designs ensures that you have an option for all locations.
The BD2 is ideal for measuring a range of water quality, flow, level and meteorological applications and has options for SDI12, modbus, analogue and pulse inputs. Additional optional power and relay outputs allows it to power up or control external pumps, autosamplers or activate alarms.
The BD2 is typically powered by a 20-watt solar panel although we do provide solar panels as small as 5-watts as well. This will ensure that you have readings 15-minute readings 24/7/365 and updated at least every hour. If solar is not an option, the internal battery will last approximately 2 months but can be extended by complimenting it with an additional battery within the enclosure. Mains back up can also be connected to the system where power is available.
With data being transferred in real-time using the latest IoT technology, all data can be viewed on our secure web portal or indeed integrated with your own SCADA or software systems, appearing like the sensor is physically connected to your system. This allows data integration on any platform; this could be a simple node reading, a read-only public graph embedded within a website or embedded control of outstations from your own system.

Furthermore, we offer street furniture options including a telemetry bollard which, will ensure that it blends in for areas where vandalism or aesthetics are critical.
