Mounting; In-Line Filter; Fluidic Connections; Piping - BRONKHORST MASS-VIEW series Instruction Manual

2.3

Mounting

The mounting position of the MASS-VIEW
change the display setting. Avoid installation in close proximity of mechanic vibration and/or heat
sources.
2.4

In-line filter

Although the gases to be measured should be absolutely free of dirt, oil, moisture and other particles,
it is recommended to install an in-line filter upstream of the flow meter / controller, and if backflow
can occur, a downstream filter is recommended too. Be aware of the pressure drop caused by the
filter.
2.5

Fluidic connections

The MASS-VIEW
manufacturer of the fittings.
While tightening fittings, do not apply excessive force, in order to avoid damaging in/output thread or
other sensitive parts of your instruments.
Please be aware when using Oxygen (O
oxygen clean.
Always check your system for leaks, before applying fluid pressure. Especially if toxic, explosive or other
dangerous fluids are used.
2.6

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 on high flow rates. At least 10 pipe
diameters distance between the angle and the instrument is recommended.
DO NOT mount pressure regulators direct on the inlet of gas flow meters/controllers, but allow some
meters of piping (at least 25 pipe diameters).
2.7

Electrical connections

The MASS-VIEW
When providing your own power supply be sure that voltage and current rating are according to the
specifications of the instrument(s) and furthermore that the source is capable of delivering enough
power to the instrument. Refer to Hook-up MASS-VIEW
details.
We recommend using our standard cables. These cables have the right connectors and if loose ends
are used, these are coloured and marked to prevent improper connection.
All cabling options can be purchased online
When using other cables, cable wire diameters should be sufficient to carry the supply current and
voltage losses must be kept as low as possible.
When connecting the system to other devices (e.g. to PLC), be sure that the integrity of the shielding is
!
not affected. Do not use unshielded wire terminals.
