Bronkhorst CORI-FLOW - Manual (Page 13)

BRONKHORST CORI-TECH B.V.
Install the sensor up side down in horizontal position for low flow (< 1000gr/h Full Scale) liquid measurement
(see the following figure) and horizontal straight up for higher liquid flows and gas measurement.
The first position, helps to remove gas bubbles out off the CORI-FLOW, the second prevents condensate
collection. In order to remove gas bubbles during start-up, flushing with relatively high flow rate for some
minutes is recommended.
Mount the CORI-FLOW always with screws in the body on a rigid support, the tubing has to be considered
flexible, because the tube diameter is relatively low. Please avoid torsion on the piping connected to de
CORI-FLOW.
For best performance please use metal installation supports for the piping or two plastic supports at each
side of the CORI-FLOW. Preferably use only rigid pipes in the system. An example is shown in the pictures
above.
Avoid abrupt pipeline reducers and other obstructions in the piping. They can cause cavitation or flashing
inside the meter tubes.
Mount reducers outside the rigid pipe supports.
Avoid connecting the sensor directly to the process pump. The piping system must be as free of vibration as
possible. Normal plant vibration has no effect on meter performance. However do not mount the sensor in
areas having abnormally high vibration.
Use a high quality valve downstream from the sensor for proper zero point calibration.
For CORI-FLOW models M52, M53, M54 two valves, upstream and downstream, are recommended.
