0 - 1 kg/h, IP65, ATEX | LIQUI-FLOW® series L10I / L20I Bronkhorst

The LIQUI-FLOW® series L10I/L20I digital Liquid Flow Meters / Controllers for low flow ranges are equipped with a rugged 'industrial style' (IP65) pc-board housing for use in industrial environments or even Zone 2 hazardous areas, due to their ATEX category 3 approval. The instruments operate on a thermal, thru-flow measuring principle. The flow meter can be connected to a control valve to form a closed control loop. The standard direct acting valve (model C2I) is normally closed, has a pressure capability of 100 bar (1500 psi) and a purge connection for easy elimination of air or gas.

Lowest range 0,25 ... 5 g/h
Highest range 20 ... 1000 g/h for fluids with thermal properties similar to H2O
