Installation
2.1
Functional properties
Before installing the mini CORI-FLOW, check the serial number label on the instrument to see if the
functional properties match your requirements:
·
Flow rate
·
Media to be used in the instrument
·
Upstream and downstream pressure(s)
·
Operating temperature
·
Valve type (if applicable; N.O. = Normally Open, N.C. = Normally Closed)
·
Technical properties (see
2.2
Operating conditions
Test pressure
Bronkhorst® instruments are pressure tested to at least 1.5 times the specified operating pressure and
outboard leak tested to at least 2 * 10
-9
mbar l/s Helium.
·
The test pressure is stated on a red label on the device; if this label is missing or if the test pressure is insufficient, the
device must not be used and should be returned to the factory.
·
Before installation, make sure that the pressure rating is within the limits of the normal process conditions and that the
tested pressure is in accordance with the safety factor of your application.
·
Disassembling and/or replacing fluid system related parts of the device will invalidate the test pressure and leak test
specification.
Sealing material compatibility
mini CORI-FLOW instruments with an integrated control valve are fitted with specific sealing material(s), compatible with
the media specified at ordering time. Be sure that the sealing materials are compatible with the media and conditions used
in the system. Bronkhorst High-Tech B.V. cannot be held responsible for any damage resulting from the use of other media
and/or conditions than specified on the purchase order.
2.3
Mounting
Use the mounting holes in the bottom of the instrument base (see
) to fixate the instrument to a firm,
rigid base or heavy, vibration free mass, such as a wall, a heavy rig or another stable construction. If such a facility is not
available, use a mass block as a mounting base (see
).
Check the
for the exact locations and size of the mounting holes.
2.3.1
Orientation
Reliability is generally not affected by the mounting orientation.
2.3.2
Location in fluid system
For
gas applications
: if there is a chance of condensation or if the gas stream can contain solid particles, it is advisable not
to mount the instrument at the lowest point of a pipe segment. In more general terms, mount the instrument in a location
where condensate or particles (if any) cannot accumulate inside the instrument's media conduits.
In
liquid applications
, the presence of gas bubbles in the liquid can cause
measurement errors. If there is a risk of expansion of dissolved gas in the
metered liquid, the instrument should be mounted in a pipe segment
where gas bubbles cannot accumulate. The image to the right shows the
preferable mounting locations.
