CORI-FILL™ Coriolis Mass Flow Meter Based Compact Fluid Dosage Assembly

Introduction Bronkhorst® manufactures Coriolis Mass Flow ­ eters and M Controllers for gases and liquids. The CORI-FLOW ­ roduct range p offers true mass flow in a range from 20 g/h up to 600 kg/h. The compact mini CORI-FLOW Series are designed for ­ apacities from c 20 mg/h up to 300 kg/h. Both mini CORI-FLOW and CORI-FLOW instruments can be combined with an actuator: ­ • hut-off valve for short time batch sequences s (down to < 0.1 sec.) • roportional valve for accurately controlled longer duration p batch sequences • gear) pump for long time accurate controlled batch sequences ( without...

CORI-FILL™ Technology CORI-FILL with shut-off valves TM All CORI-FLOW instruments are capable of operating with both +24Vdc electric shut-off valves and pneumatic valves. Electric valves can be operated within a special power ­ aving mode to s reduce energy consumption and minimize temperature i ­ncrease thereby reducing the risk of fluid evaporation. TM 0 Counter value Density Temperature Setpoint Measure Controller output Typical response curve CORI-FILL technology includes an automatic overrun cor­ec­ion ­ r t on batch dosing. After just a few doses the ­ ccuracy will be a o ­ ptimized...

CORI-FILL with proportional valves and pumps TM All CORI-FLOW instruments are capable of operating with propor­ tional valves or (gear) pumps using the integrated PID-controller. ­ Thanks to CORI-FILL technology, all batch counters now have an e ­ xtra P-controller to make the valve close or make the pump stop smoothly as soon as the batch total is reached. TM Benefits • “First time right” batch (no overrun correction needed) • Suitable for longer dosing times (> approx. 3 seconds) • Also applicable for pump control Liquid dosing system consisting of a mini CORI-FLOW Mass Flow Meter, TM...

CORI-FILL™ Alternative to gravimetric method Existing applications using weighing scales (the gravimetric method) Improved dosing applications using Coriolis i ­ nstruments with CORI-FILL technology Traditionally, dosage of mass/volume is achieved by using a shut-off ­ valve with a weighing scale/balance. The weighing scale is located under a valve outlet nozzle and, after a zeroing procedure, the valve ­ will open. The weighing scale will send a signal to PLC or control unit ­ and when the batch has been reached the valve will lose. Eventually the weighing scale will move to another valve...

Examples M14 with integrated shut-off valve, dosing 5 gram into a cup with a flow speed of 30 kg/h water takes 0.6 seconds and giving ­ highly accurate and reproducable results. Testing of pumps or batching with pumps with pulsating flows is possible now thanks to CORI-FILLTM technology. The very fast and accurate batch counter will be able to ­integrate also very pulsating or fluctuating flows. This also can make weighing scales superfluous. When a piston pump pulsates with max. 2...3 pulses per second, the totalized flow can be ­integrated with approx. 1% accuracy. mini CORI-FLOW with...
