VRS-20 Radar Level Sensor

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The VRS-20 is a 24 GHz 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. Communication is conducted via three standard methods, RS232, RS485 and SDI 12. With a wide range 9 – 28v DC power supply, integrated spirit bubbles for leveling and a bar fixing for GPS antenna use, the VRS-20 is both versatile and simple to install.

VRS-20 addresses a number of the issues traditionally associated with water level measurement through non-contact technology which removes the installation, corrosion & fouling issues of submerged sensors
