Gauger420 is a rich featured ultrasonic level sensor and level transmitter for liquid and solids applications. A 2-wire, loop-powered system featuring 4-20mA, HART and RS485. A USB interface for configuration, monitoring and firmware upgrades. Gauger420 can track liquid targets rising as rapid as 10 meters per minute (33'/min)and exhibits an extremely short dead zone of 15cm (6"). Gauger420 can also be applied to Open Channel Flow (OCF) applications (flow and totalization) and to volume applications in tanks.
