mini CORI-FLOW® Liquid Dosing Systems,
using flow meter controlled pumps

An alternative way of control

In some applications it is not possible or not recommended to use a control valve, for instance when a vessel with liquid cannot be pressurised. As an alternative, Bronkhorst Cori-Tech can offer virtually pulse-free gear pumps, close-coupled to the Coriolis flowmeter.

Liquid dosing system

A mini CORI-FLOW® liquid dosing system consists of a Coriolis flow meter, a gear pump, a filter, a check valve and interconnecting material. Furthermore Bronkhorst Cori-Tech will take care of electrical and mechanical connection, testing and optimisation including the PID-integrated controller.

Mass Flow Meter, close-coupled to a gear pump and a protective filter, with check valve at the outlet

A complete series of pumps is available for very small through to higher flow rates, for higher pressures, wide control ranges and for aggressive fluids. Further to operation in analog mode, the Liquid Dosing System can also be used digitally with RS232 or with an on-board fieldbus interface.

Features

  • simple and compact assembly; easy to use
  • no need to pressurise liquid source
  • pump controlled by mass flow instrument with adjustable PID-controller via voltage output signal
  • complete dosing system with small dimensions
  • direct mass flow measurement/control (not volumetric)
  • high accuracy and stability (nearly pulse free)
  • desired flow to be set via: analog 0…5(10) V / 0(4)...20 mA or digital communication by RS232, Profibus-DP®, DeviceNet™, Modbus-RTU, LonWorks or FLOW-BUS
