packaged solution
Features

Deliver an accurate moisture measurement with thePanametrics pro.IQ. The new moisture analyzer packaged
solution simplifies the selection and installation of yourmoisture analyzer. Only a few simple steps; install themoisture transmitter, and connect your loop power andsample gas or liquid to the inlet fitting and you are readyto measure. Other benefits include:• IP66 and NEMA 4X package• The moisture transmitter, sample system and Zenerbarrier (if ATEX Zone 1 or Class I Div. 1 hazardous area
option selected)Applications

The standard pro.IQ package is designed for moisturemeasurements in hydrocarbon gas, liquid or inert gas
application. It may be used in environments classified as safeor hazardous areas, where the process gas or liquid pressure
is up to 200 psig (14 bar) in safe areas, 400 psig/27 bar (gassystem) or 500 psig/34.5 bar (liquid system) in hazardous
area. The system combines the Panametrics HygroProII withover 50 years of sample system design experience, to deliver
the moisture measurement you have come to trust.
Markets and applications served include:• Natural gas• Features the HygroPro moisture transmitter• Hydrocarbon gases• Sample system provides isolation, filtration, pressure
indication on gas systems and flow indication on bothgas and liquid systems. Enclosure is available in 304SS
and 316SS and has a clear door for viewing all readings.
Optional heater is also available.

Start-up procedure• Insert moisture transmitter into the sample cell andconnect earth to ground connection of the transmitter.
• Follow HygroProII manual wiring instructions to connect
power, pay special attention to zener barrier installation
and wiring if in hazardous area.
Gas application• For gas applications with potential light liquidcontaminant, install the fibre filter element (suppliedloose) in the filter housing, removing the particulate
filter element already installed.
• Start with the inlet valve, the drain valve and the sample
outlet valve fully closed.
• For measurement at process pressure, slowly open theinlet valve until fully open; then crack the sample outlet
valve to get flow on mid-range of the flowmeter scale.
• For measurement at atmospheric pressure, fully open
the sample outlet valve; then crack the inlet needle valve
to get flow on scale.
• For applications with potential light liquid contaminantcrack the drain needle valve to ensure continuous removalof any liquid mists from the sample gas.
*Use appropriate filter element supplied

Liquid application• Start with the inlet valve, the drain valve and the sample
outlet valve fully closed.
• Slowly open the inlet valve until fully open; then crack
the sample outlet valve to get flow on mid-range of theflowmeter scale.

Shut-down procedure• Slowly close the inlet needle valve.

• Slowly open the drain needle valve until the pressure on
the pressure gauge (or for liquid systems, the pressure
reading on the HygroProII display) is 0 psig.
• Remove the moisture transmitter.Panametrics, a Baker Hughes business, provides solutions in
