1 INTRODUCTION
1.1 General description
1.1.1 Gas / Liquid flow
The Bronkhorst Cori-Tech B.V. series mini CORI-FLOW mass-flow meter/controller for gases and liquids is an
accurate device for measuring gas and liquid flows up to 200 bara depending on body rating, virtually
independent of pressure and temperature changes. The mini CORI-FLOW is a real mass-flow meter/controller
and measures the flow in mass, it does not matter what the properties of the gases or liquids are. The system
can be completed with a control valve or a pump and flexible readout unit to measure and control gas and
liquid flows.
Mini CORI-FLOW series by Bronkhorst Cori-Tech B.V. are precise and compact Mass Flow Meters and
Controllers, based on the Coriolis measuring principle. Designed to cover the needs of the low flow market,
there are 4 models to overlap flow ranges from 5 g/h up to 300 kg/h (full scale values), each offering “multi-
range” functionality: factory calibrated ranges can be rescaled by the user, maintaining the original accuracy
specs. The instruments are equipped with a robust IP65 weatherproof housing.
Instruments of the mini CORI-FLOW series contain a uniquely shaped, single loop sensor tube, forming part of
an oscillating system. When a fluid flows through the tube, Coriolis forces cause a variable phase shift, which
is detected by sensors and fed into the integrally mounted pc-board. The resulting output signal is strictly
proportional to the real mass flow rate. Coriolis mass flow measurement is fast, accurate and inherently bi-
directional. The mini CORI-FLOW features density and temperature of the fluid as secondary outputs.
1.1.2 Housing
Each instrument housing style incorporates several provisions to comply with EMC requirements.
Also the instrument housing is a robust IP65 weatherproof housing.
