2.6 Fluid/gas connections

Bronkhorst Cori-Tech B.V. mini CORI-FLOW meters/controllers are equipped with compression or face-seal-

fittings. For leak tight installation of compression type fittings make sure that the tube is inserted to the

shoulder in the fitting body and that no dirt or dust is present on tube, ferrules or fittings. Tighten the nut finger-

tight; while holding the instrument and then tighten the nut 1 turn.

If applicable follow the guidelines of the supplier of the fittings. Special types of fittings are available on request.

* Note: Always check your system for leaks, before applying fluid/gas pressure. Especially if toxic, explosive or

other dangerous fluids are used.

2.7 Piping

BE SURE THAT PIPING IS ABSOLUTELY CLEAN!

DO NOT install small diameter piping on high flow rates, because the inlet jet-flow will affect the accuracy.

DO NOT mount abrupt angles direct on in- and outlet, especially not with high flow rates. We recommend at

least 20 pipe diameters distance between the angle and the instrument.

Special care should be taken in regard to reducers placed just in front of the mini CORI-FLOW. High pressure

drop and flow disturbance can occur which can influence the mini CORI-FLOW.

2.8 Electrical connections

Bronkhorst Cori-Tech B.V. recommends using their standard cables. These cables have the right connectors

and if loose ends are used, these will be marked to prevent wrong connection.
