The Aquadar Radar water level sensor is a 0.4m to 35m measurement range instrument with +/-2mm (0.007ft) accuracy that meet USGS accuracy requirements.  It is a non-contact stage measurement sensor that represents a new type of level measurement for surface water which offers many advantages in hydrological field applications. The main advantage of the Aquadar is it does not come in direct contact with the water. Thanks to its compact design and the non-contact measuring principle, the sensor can be installed easily and inconspicuously. With the Aquadar, problems like disruption of measuring operation caused by high-water silt accumulation, debris, plant growth, etc., as well as time-consuming maintenance are eliminated.

Cumbersome stilling wells are replaced by an integrated software filter for averaging wave motion. The measuring signals are transferred to a data logger by means of a RS485 or SDI-12 interface, over distances of up to 1000 m. A power supply of 12 V (rechargeable battery, solar energy) and low power consumption enable the device to operate independently in the most remote areas. Aquadar is particularly suitable for areas where conventional measuring systems cannot be used or where a station needs to be set up quickly.

The Aquadar can be fitted easily and quickly, on a bridge, measuring frame or 'extension arm', for example. The Aquadar sends radar waves (microwaves) perpendicular to the water surface. An intelligent signal processor calculates the exact distance between the sensor and the surface of the water.

Digital measured values, status values and any error messages present are scanned by means of an external data logger via the RS 485 interface.

Features:

  • Non contact measuring principle, no damage caused by silt cumulation or debris
  • Simple, inexpensive installation - no difficult fitting procedure necessary
  • 12 V DC power supply; low power consumption enables operation with rechargeable batteries or solar
  • Cost reduction due to low maintenance requirements
  • RS485 Interface, optional SDI 12 signal (RS 485 - SDI-12 converter)
  • Integrated lightning protection fitted as standard
  • Robust, weatherproof housing (IP 68)
  • RS 485 Interface:
  • digital data transmission up to 1000 m (3,000 ft) distance
  • Transmission rate 9600 bps
  • Cable Connection Radarsensor to datalogger. Standard length 3 m (10 ft.)
