Cautions for Device Applications
Do Not attempt to disassemble, substitute parts or perform unauthorized
modifications to this device. Doing so will void the warranty. This device
contains no user serviceable components and should be serviced by authorized
personnel only.
Do Not use this device in explosive, wet or corrosive environments.
Do Not flow any corrosive gases such as: Ammonia, Propylene, HCl, SO2,
H2S, NO2, NO, Silane, Chlorine, etc.
Do Not flow gas in conditions that can cause condensing water vapor to be
trapped inside the unit as the pressure sensors can be destroyed.
Do Not use a meter with a flow range beyond what you really need, for
example: do not use a 1000 liter unit for a 100 liter application.
Do size your meter so that nominal flow rate is approximately 70% of the full
scale flow rating of the meter.
Cautions for Device Installations
Do Not use snap shutting/opening valves where the unit can be exposed
to high pressure transients — this is especially important for low flow range
(50SCCM and lower) units with tiny flow channels — damage can occur to the
differential pressure sensor.
Do Not use a controller's valve assembly for leverage when tightening or
removing fittings — the valve is a precision device, any bend in the valve stem
will affect the controlling capability of the unit.
Do Not expose the unit’s outer surface to any liquids, the unit does not have a
water tight electronics package.
Do power your unit with the correct polarity, voltage & amperage.
Do carefully check your wiring hookups before power up when using a DC-61
or other blunt cut cable.
Do use a filter system upstream of the unit if possible (20 – 50 microns).
