mini CORI-FLOW^® Mass Flow Meters

General

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 3 models to overlap flow ranges from 20 g/h up to 30 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 and are available with ATEX approval for use in Zone 2 hazardous areas.

Superior Coriolis flow sensor

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.

Fields of application

mini CORI-FLOW^® instruments can be applied for both gases and liquids in process fluid measurement or control systems in semiconductor processing, in fuel cell technology, in food, (petro-) chemical and pharmaceutical industries or analytical installations (e.g. GC, HPLC or SFC systems measuring / dosing supercritical CO₂) and in liquid dosing systems for micro reactors, amongst many others.

Features

• high accuracy, excellent repeatability
• easy to re-range (multi-range)
• IP65 design, ATEX approval Cat.3, Zone 2
• metal-sealed construction
• optional bi-directional measurement
• additional density and temperature outputs
• standard analog 0…5(10) Vdc and 0(4)…20 mA and digital communication
• optional fieldbus interface (DeviceNet^TM, PROFIBUS-DP^®, Modbus-RTU, LonWorks or FLOW-BUS)
• alarm and (batch) counter functions

Capacities

Model	Smallest range	Nominal range	Highest range*
M12	0.4…20   g/h	1…100 g/h	2…200    g/h
M13	1…50  g/h	10…1000 g/h	20…2000  g/h
M14	0.03…1   kg/h	0.1…10 kg/h	0.3…30    kg/h

* Maximum capacities depend on the available pressure difference across the mass flow meter, especially when used on gases.
