LIQUI-FLOW™ series L10 / L20
digital Liquid Mass Flow Meters / Controllers
General
LIQUI-FLOW™ Series L10/L20 are digital Liquid Flow Meters/Controllers
for low flow ranges. 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.
Lowest range 0,25 ... 5 g/h
Highest range 20 ... 1000 g/h for fluids with thermal properties similar
to H2O
Note:
For ultra low flow ranges, Bronkhorst High-Tech offers the µ-FLOW series.
Ranges: 1,5 ... 30 mg/h up to 0,1 ... 2 g/h IPA- or H2O-equivalent
Liquid Flow Controllers
Flow control is achieved by integrating a control valve onto the body
of the Liquid Flow Meter. This control valve has a purge connection to
eliminate air or gas during start-up. The electronic control function forms
part of the normal circuitry in the meter.
