  Via serial port

Gauge Link NXA20 scans parameters from tank gauges with TRL/2 protocol from Emerson Rosemount or BPM protocol from Honeywell Enraf and converts the signal to Modbus RS485 as one part of Tankvision, which is a dedicated tank inventory system. For a step-by-step site upgrade, the Tankvision Gauge Link together with the Tankvision Tank Scanner allows legacy protocol management as well as gradual upgrades for more flexibility. It is ideally suited for small depots as well as bigger tank farms.

Scans parameters from tank gauges. Suited for tank farms with various protocols used for communicating with the installed field devices.
