The VRS-20 is a pulsed k-band radar level sensor developed by Valeport to work seamlessly with the TideMaster tide logger, operate standalone with optional integrated GPRS telemetry or interface to a third party data logger.
Versatile and simple to install, the VRS-20 addresses a number of the issues traditionally associated with water level measurement.
