pro.IQ moisture transmitter
packaged solution
Features
pro.IQ simplifies the selection and installation of your
moisture transmitter for a complete moisture measurement
solution. Only a few simple steps; install the moisture
transmitter, connect your loop power and sample gas to the
inlet fitting and you are ready to measure. Includes:
• IP66 & NEMA 4X package
• The moisture transmitter, sample system and Zener barrier
(if hazardous area option selected)
• Features the HygroPro moisture transmitter
• Sample system to provide isolation, filtration, pressure
and flow indication, with a clear door for easy viewing of
all readings
Applications
The standard pro.IQ package is designed for moisture
measurements in any hydrocarbon gas or inert gas
application. It may be used in environments classified as
safe or hazardous areas, where the process gas pressure
is up to 200 psig (14 bar) in safe area and 400 psig (27 bar)
in hazardous area. The system combines the Panametrics
HygroPro with 50 years of sample system design experience ,
to deliver the moisture measurement you have come to trust.
Markets and applications served include:
• Natural gas
• Hydrocarbon gases
• Petrochemical
• Metal heat treatment
• Industrial gas
• Power generation

Start-up procedure
• Insert moisture transmitter into the sample cell and
connect earth to ground connection of the transmitter
• Follow HygroPro manual wiring instructions to connect
power, and zener barrier installation and wiring if in
hazardous area
• Two filter elements are provided. Sintered steel for clean
gases and liquids. Fiber for gases with entrained liquids or
aerosols. Install the filter element most appropriate for the
application
• Start with the inlet valve NV1, the drain valve NV3 and the
sample outlet valve NV2 fully closed
• For measurement at process pressure, slowly turn the inlet
valve NV1 until fully open; then crack the sample outlet
valve NV2 to get flow on mid range of the flowmeter scale
• For measurement at atmospheric pressure, fully open
the sample outlet valve NV2; then crack the inlet needle
valve NV1 to get flow on scale
• For applications with potential light liquid contaminant
crack the drain needle valve NV3 to ensure continuous
removal of any liquid mists from the sample gas
Shut-down procedure
• Slowly close the inlet needle valve NV1
• Close outlet needle valve NV2 fully
• Slowly open the drain needle valve NV3 until
the pressure on the pressure gauge is 0 psig
• Remove the moisture transmitter
