About this file
This document is a Salient Characteristics specification for a Non-Contact Radar Water Level Sensor for the U.S. Geological Survey (USGS) Hydrologic Instrumentation Facility. The specification details precise technical requirements for water level measurement sensors, specifically seeking a device like the VegaPuls C 23 Radar Water Level Sensor or an equivalent model with 80 GHz measurement frequency technology.
The sensor must meet stringent performance criteria, including a measurement uncertainty of no more than 0.01 ft or 0.1% of indicated reading, a measurement range of 0 to 30m, a narrow 4° beam angle, and an operating temperature range of -40° to 60°C. Additional mandatory features include 12 VDC power source compatibility, an SDI-12 interface, IP66/68 mechanical rating, integrated Bluetooth communication, a 15 ft communication/power cable, and an optional mounting bracket. These sensors will be used for water level measurements at data collection sites nationwide.

Salient Characteristics
Non-Contact Radar (Model VegaPuls C 23 Radar Water Level Sensor or equal)
The USGS Hydrologic Instrumentation Facility needs to purchase non-contact radar water level sensors with 80 GHz measurement frequency technology. This equipment will be used for measuring water levels at data collections sites all over the country.
Non-Contact Radar
Shall meet USGS requirements for stage accuracy measurements and shall measure stage with a total measurement uncertainty of no more than 0.01 ft. or 0.1% of indicated reading, whichever is larger over a temperature range of at least -40° to 60°C.
Shall be capable of a measurement range up to at least 0 to 30m (0 to 98 feet).
Shall use 80 GHz measurement frequency technology.
Shall have a beam angle that is no larger than 4o.
Shall be capable of an operating temperature range of at least -40° to 60°C.
Shall be powered from a 12 VDC (nominal) power source.
Shall include an SDI-12 interface.
Shall have a mechanical IP rating of at least IP66/68.
Shall have an integrated Bluetooth communication interface.
Shall include an integral SDI-12 communication/power cable that is at least 15 ft. long.
Shall have an option for a mounting bracket.
