Working on the Kármán-vortex principle, a bluff body inside the meter generates vortices whose frequency is proportional to flow velocity; counting these vortices yields instantaneous and totalised flow. The pipeline version covers DN10–DN500 with ±1.0 % accuracy for liquids and ±1.5 % for gases or steam, and retains a low pressure drop thanks to its streamlined body. Standard outputs include isolated 4-20 mA, frequency/pulse and RS-485 (Modbus-RTU), powered either by 24 V DC or an internal 3.6 V lithium battery for remote sites. With no moving parts, the SUP-LUGB offers long-term stability and requires only minimal maintenance.
