Mass Flow Meters and Controllers for liquids in ranges between
0…5 g/h and 0…20 kg/h (water equivalent). LIQUI-FLOW® flow
meters only require a small differential pressure. Despite utilizing
direct measurement (i.e. without a by-pass) the temperature rise
of the fluid is minimal; only approx. 1…5 °C. This greatly limits
the danger of evaporation or degradation of the fluid.
> Features
u fast and accurate measuring signal
u analog (models L1/L2) and digital (models L10/L20/L30)
versions available
u thru-flow measurement (no by-pass)
u insensitive to mounting position
> Flow ranges (based on water)
smallest 0…5 g/h, highest 0…20 kg/h
For ultra low flow ranges of liquids Bronkhorst High-Tech developed
the ì-FLOW series for 0…30 mg/h up to 0…2 g/h water equivalent.
The thermal Mass Flow Meters can be close-coupled to a LIQUIFLOW®
control valve for pulsation-free control.
> Features
u neglegible internal volume
u analog and digital (fieldbus) communication
u insensitive to mounting position
u suitable for HPLC-applications
> Flow ranges (based on water)
smallest 0…30 mg/h, highest 0…2 g/h
The CEM-System (Controlled Evaporation and Mixing) is an innovative
Liquid Delivery System that can replace traditional Bubbler Systems.
It consists of a liquid flow controller, an MFC for carrier gas and
a temperature controlled mixing and evaporation device. The system
is suitable for mixing liquid flows of 0,25…1000 g/h resulting
in saturated vapor flows of 50 mln/min to 100 ln/min.
> Features
u accurately controlled gas/liquid mixture (mass flow)
u fast response
u very stable vapour flow
u handles water, solvents, liquid mixtures
