Installation
2.1
Check properties
Before installing the FLOW-CONTROL, check if the properties match your requirements:
·
Model type
·
Maximum operating pressure
·
Ambient temperature range
The FLOW-CONTROL is 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. Mass Flow ONLINE 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.
Bronkhorst® instruments are pressure tested; the tested pressure and the maximum process pressure are stated on the
instrument label. If the instrument label is missing, or if the maximum process pressure and/or tested pressure are
insufficient, the instrument must not be used and should be returned to the factory.
Before installation, make sure that the tested pressure is in accordance with the safety factor of your application. The tested
pressure must always be higher than the maximum operating pressure.
Disassembling the instrument will invalidate the pressure test specification.
2.2
Mounting
The FLOW-CONTROL has no preferred mounting position or orientation.
2.3
Fluidic connections
When installing fittings, do not apply excessive force, as this may cause damage to the threads or other sensitive parts of the
instrument. Tighten the nut finger tight, while holding the instrument, then tighten it further for 1 turn at most.
If oxygen (O
2
) is to be used in the instrument, fittings must be degreased before mounting them to the body.
Install the FLOW-CONTROL in the process line, in accordance with the direction of the FLOW arrow on the serial number
label. Tighten fittings according to the instructions of their supplier. The use of Swagelok RS-type stainless steel adapters is
recommended.
For reliable performance, make sure the fluid stream is uncontaminated.If necessary, use filters to assure a particle free
fluid stream. Select a suitable filter size, to avoid a too high pressure drop.
Do not install small diameter piping on high flow rates and avoid abrupt angles or other disturbances within a distance of
10 pipe diameters from the inlet or outlet of the device.
Do not install pressure regulators within a distance of 25 pipe diameters.
