The Valeport VRS-20 is a pulsed k-band radar level sensor developed to work seamlessly with the Valeport TideMaster, operate standalone with optional integrated GPRS telemetry to internet, or interface directly to a third party datalogger or PC. Versatile and simple to install, the Valeport VRS-20 Radar Level Sensor addresses a number of the issues traditionally associated with level measurement. Non-contact technology removes the installation, corrosion & fouling issues of submerged sensors, while simplifying datum control. Accuracy and performance are unaffected by changes in water density and atmospheric conditions.
