RangeVue 15 SDI-12, Radar Water-Level Sensor
Non-Contact Water-Level Monitoring
Distance up to 15 meters
weather applications water applications energy applications gas flux and turbulence applications infrastructure applications soil applications

Overview

The RangeVue™️15 is a non-contact, radar water-level sensor used for monitoring the water level of rivers, lakes, and reservoirs. Using 80 GHz radar technology, it directly measures the distance between the sensor face and the water surface. This distance can be used to determine water level or stage. The sensor is ideal for areas where submersible sensors can be damaged due to corrosion, contamination, flood-related debris, or lightning. 

Benefits and Features

  • Non-contact water-level measurement
  • Meets United States Geological Survey (USGS) Office of Surface Water (OSW) requirements for accuracy
  • SDI-12 version 1.4 functionality
  • Configurable over SDI-12
  • Bluetooth-configurable over smartphone, tablet, or PC

RangeVue Program Examples (1 KB) 12-07-2024

Two programs use the C1! SDI-12 instruction to measure the RangeVue-series sensors. One program is for the CR350 data logger and one program is for the CR1000X data logger. The program sets the Stage_Reference value to 15.25. This value needs to be changed to your stage reference value. Also, the SDI-12 address is entered as a constant with a value of 0. If the SDI-12 address of the sensor has been changed from the default value, this value needs to be changed to match the sensor address. The program sets the Sensor_Units variable to feet (option 1), which needs to be changed if using other units. See comments in the program for details.
