RSS-2-300 WL Flow Meter
The Geolux RSS-2-300 WL flow velocity and level meter uses radar technology to provide precise, contactless measurement of surface flow velocity, and to measure the distance from the sensor to the water level. Contactless radar technology enables quick and simple sensor installation above the water surface, and requires minimum maintenance.
- Contactless flow measurement
- Instrument combined from two sensors:
surface velocity radar and
radar level sensor - Integrated discharge calculation in the instrument
- Wide velocity measurement range from 0,02 m/s to 15 m/s
- Distance measurement range from 0,5 m to either 15 m or 30 m, depends on device model
- Compact, low-power design
- Wide input voltage range, suitable for solar applications
- IP68 aluminum casing
- Supports variety of communication interfaces (RS-232, RS-485, CAN, Alarm open-drain outputs)
- Optional SDI-12 support
- Automatic mounting angle compensation (cosine correction)
- Easy pole, wall or enclosure mounting
- Operating temperature range from -40 °C to +85 °C (-40 °F to +185 °F)
