Chapter 1. Installation
1.4 Choosing an Installation Site
You should have discussed environmental and installation factors with a BHGE applications engineer or field
sales person by the time you receive the meter. The equipment provided should be suited to your application
and installation site.
The moisture.IQ is available in rack-mount, bench top, or panel-mount versions that are suitable for most
indoor installations. BHGE also provides weatherproof and explosion-proof housings for outdoor and
hazardous area locations. See the drawings in the Certification and Safety Statements at the end of this manual
for details of each enclosure.
Before installing the unit, read the guidelines below to verify that you have selected the best installation site.
1.4.1 General Site Guidelines
• Choose an installation site for the probes and sample systems that is as close to the process line as
possible. Avoid long lengths of connecting tubing. If long distances are unavoidable, a fast sampling
by-pass loop is recommended. Do not install any other components, such as filters, upstream from the
probes or sample system unless instructed to do so by BHGE.
• Observe all normal safety precautions. Use the probes within their maximum pressure and
temperature ratings.
• Although the moisture.IQ may not need to be accessed during normal operation, install the electronics
unit at a convenient location for programming, testing and servicing. A control room or instrument
shed are typical locations.
• Locate the electronics unit away from high temperatures, strong electrical transients, mechanical
vibrations, corrosive atmospheres, and any other conditions that could damage or interfere with the
meter operation. See Chapter 9. “Specifications” on page 99 for environmental limits.
• Protect the probe cables from excessive physical strain (e.g., bending, pulling, twisting, etc.).
• Observe the proper cable restrictions for the probes. You can locate Moisture Image Series probes up to
915 m (3000 ft) from the electronics unit with unshielded twisted-pair cable. M-Series probes can be
located up to 600 m (2000 ft) from the unit with the use of specially shielded cable.
1.4.2 Low Voltage Directive
If the power mains switch on the unit remains accessible to the user after installation a disconnect device is
not required. However, if installation blocks access to the power mains switch, compliance with the EU Low
Voltage Directive (IEC 61010) requires an external power disconnect device such as a switch or circuit breaker.
The disconnect device must be marked as such, clearly visible, directly accessible, and located within
1.8 m (6 ft) of the unit.
2 moisture.IQ User’s Manual
Chapter 1. Installation
1.5 Moisture Probe Considerations
The M-Series and Moisture Image Series probes consist of an aluminum oxide sensor mounted on a connector
head. Standard probe mounts include a protective stainless steel shield.
The probe sensor materials and housing maximize durability and insure a minimum of water absorbing
surfaces in the vicinity of the aluminum oxide surface. A sintered stainless steel shield is used to protect the
sensor from high flow rates and particulate matter. The end cap should not be removed except upon advice
from BHGE.
The sensor has been designed to withstand normal shock and vibration. You should make sure that the active
sensor surface is never touched or allowed to come into direct contact with foreign objects, since this may
adversely affect performance.
Observing these few simple precautions will result in a long and useful probe life. BHGE recommends that
probe calibration be checked routinely, at 12-month intervals, or as recommended by our applications
engineers for your particular application.
The probe will measure the water vapor pressure in its immediate vicinity. Therefore, readings will be
influenced by its proximity to the system walls, materials of construction, and other environmental factors.The
sensor can be operated under vacuum or pressure and under flowing or static conditions.
See the following sections for the recommended environmental precautions.
1.5.1 Temperature Range
See “Probe Specifications” on page 105, for details.
1.5.2 Moisture Condensation
Be sure the temperature is at least 10°C higher than the dew/frost point temperature. If this condition is not
maintained, moisture condensation could occur on the sensor or in the sample system, which will cause
reading errors. If this happens, dry out the probe following the procedures outlined in BHGE document
#916-064, Basic Hygrometry Principles.
1.5.3 Static or Dynamic Use
The sensor performs equally well in still air or where considerable flow occurs. Its small size makes it ideal for
measuring moisture conditions within completely sealed containers or dry boxes. It will also perform well
under gas flow conditions as high as 10,000 cm/sec and liquid flow conditions up to 10 cm/sec. Refer to BHGE
document #916-064, Basic Hygrometry Principles, for maximum flow rates in gases and liquids.
moisture.IQ User’s Manual 3
Chapter 1. Installation
1.5.4 Pressure Range
The moisture probe always senses the correct water vapor pressure regardless of the total ambient pressure.
The moisture sensor measures water vapor under vacuum or high pressure conditions from as little as a few
microns of Hg to as high as 5000 psi total pressure.
1.5.5 Long-Term Storage & Operational Stability
Sensors are not affected by continuous abrupt humidity changes or damaged by exposure to saturation
conditions even when stored. However, you should store probes in their original shipping containers in a clean,
dry location. If the probe is saturated during storage, refer to “Moisture Condensation” on page 3 before
installing the probe. For best performance, do not store probes longer than one to two years from their
calibration date.
1.5.6 Interference Effects
The sensor is completely unaffected by the presence of a wide variety of gases or organic liquids. Large
concentrations of hydrocarbon gases, Freon
effect on sensor water vapor indications. The sensor will operate properly in a multitude of gaseous or
non-conductive liquid environments.
, ozone, carbon dioxide, carbon monoxide, and hydrogen have no
1.5.7 Corrosive Materials
Avoid all materials that are corrosive or otherwise damaging to aluminum or aluminum oxide. These include
strongly acidic or basic materials and primary amines.

Chapter 1. Installation
1.6 Sample System Guidelines
A sample system is required for oxygen measurement and, although not mandatory, is highly recommended
for moisture measurement. The purpose of a sample system is to condition or control a sample stream to
within the specifications of a probe. The application requirements determine the design of the sample system.
BHGE applications engineers will make recommendations based on the following general guidelines.
1.6.1 Moisture Sample Systems
Typically, sample systems should be kept very simple. They should contain as few components as possible and
all or most of those components should be located downstream of the measurement probe. Figure 1 below
shows an example of a basic sample system consisting of an explosion-proof housing with a sample cell, a
filter, a flow meter, a vent valve, an inlet shut-off valve and an outlet shut-off valve.
The sample system components should not be made of any material that will affect measurements. A sample
system may include a filter to remove particulates from the sample stream or a pressure regulator to reduce or
control the pressure of the stream. However, most common filters and pressure regulators are not suitable for
sample systems because they have wetted parts that may absorb or release components (such as moisture) into
the sample stream. They may also allow ambient contamination to enter the sample stream. In general, you
should use stainless steel construction for all wetted parts. Contact BHGE for further instructions.

Chapter 1. Installation
1.6.2 Oxygen Sample Systems
Oxygen sample systems are required and can be ordered from BHGE for bench or wall mounting. You can also
build your own sample system by using the following guidelines.
IMPORTANT: The BHGE warranty will be voided if the sample system does not have a relief valve.
The basic sample system requirements are as follows (see Figure 2 below):
• The oxygen cell requires a sample gas flow of 0.5 to 1 LPM (1 to 2 SCFH).
• The gas pressure in the sample cell must be between 0.0 and 1.0 psig. The pressure must not exceed
1.0 psig.
• A 10 psig pressure relief valve installed upstream of the oxygen cell is required to prevent
over-pressure.
• A flow meter is required to measure the flow.
• A pressure gauge is required to measure the pressure.
• A flow regulating or needle valve is required and should be located upstream of the sample cell.
• A pressure regulator is required for sample gas supplies of 50 psig or greater.
If a sample pump is required to draw a sample to the oxygen cell, the pump should be installed downstream
from the oxygen cell. You must also install a vacuum relief valve set at 1.0 psig between the oxygen cell and the
pump.

1.7 Mounting the Hygrometer System
Mounting the hygrometer system consists of mounting the electronics unit, the probes, and the sample
systems.
1.7.1 Mounting the Electronics Unit
Use the outline and dimension drawings in the Certification and Safety Statements at the end of this manual to
mount the moisture.IQ. These drawings provide clearance and other mounting dimensions needed to prepare
the site for mounting.
WARNING! If the power mains switch on the unit remains accessible to the user after installation, a
disconnect device is not required. However, if the installation blocks access to the power mains switch,
compliance with the EU's Low Voltage Directive (IEC 61010) requires an external power disconnect
device such as a switch or circuit breaker. The disconnect device must be marked as such, clearly visible,
directly accessible, and located within 1.8 m (6 ft) of the unit.
Be sure to follow the guidelines outlined in “Choosing an Installation Site” on page 2 before mounting the
enclosure.
Note: If the installation location does not provide enough room for connections to be made easily after
installation, you may want to make connections to the MIS or M-Series probes, Delta F Oxygen Cell,
Outputs and Alarms before mounting the instrument.
1.7.2 Mounting a Sample System
BHGE sample systems are normally fastened to a metal plate that has four mounting holes. BHGE can also
provide the sample system in an enclosure, if requested. In either case, fasten the sample system plate or
enclosure with bolts in the mounting holes at each of the four corners. If you ordered sample system outline
and dimension drawings, they will be included in your shipment.
Connect the sample system inlet to the process and the outlet to the return, using the appropriate fittings or an
appropriate NPT adapter.
CAUTION! Do not start a flow through the sample system until all probes and transmitters are
properly installed.

1.8 Installing the Probes
After you mount the sample system, you must insert the moisture probes into the sample cells. In addition, you
must check, prepare, and connect any installed oxygen cells to the gas line.
1.8.1 Moisture Probes
BHGE Moisture Image Series (MIS) and M-Series moisture probes have 3/4 inch-16 straight threads, with an
O-ring seal, to the secure probes into the sample system or directly into the process line. Other fittings are
available for special applications.
CAUTION! If mounting the moisture probes directly into the process line, you must consult BHGE for
proper installation instructions and precautions.
Moisture probes are usually installed into a sample system. The sample system protects the probes from
coming into contact with damaging elements in the process. Moisture probes are installed into a cylindrical
shaped container, called the sample cell, which is included as part of your sample system. The sample cell is
identified by a label on the sample system plate.
To install a moisture probe that has a 3/4 inch-16 straight thread, insert it into the sample cell so it is
perpendicular to the sample inlet. Screw the probe into cell, making sure not to cross thread it, and tighten it
securely. Figure 4 below shows a typical moisture probe installation, with the probe mounted in a BHGE
sample cell. Install any moisture probes with different fittings in the appropriate manner.

Outlet
Figure 4: Typical Moisture Probe in Sample Cell
Note: Standard moisture probes have a sintered stainless steel shield that protects the aluminum oxide sensor.
Be sure to leave the shield in place for maximum protection.
It is important to eliminate all gas or liquid leaks for safety reasons and to ensure that measurements are not
affected by ambient contamination. For gas applications, you should check for leaks using a soap bubble
solution.
IMPORTANT: Refer to the Calibration Data Sheets to connect the probes to their corresponding channels. If a
probe is connected to the wrong channel, the meter will display incorrect data.

1.8.4 Pressure Sensors
If a pressure input is required and if an optional pressure signal is not available from a Moisture Image Series
probe, you can connect a separate pressure transmitter to an auxiliary input.
The moisture.IQ accepts any 0 to 20-mA, 4 to 20-mA, or 0 to 2-V pressure transmitters.
Always mount the pressure transmitter directly downstream from the moisture probe to ensure that the
pressure is measured at the same point as the moisture measurement.
1.8.5 Delta F Oxygen Cell
Although the moisture.IQ accepts other oxygen devices as auxiliary inputs, it is designed to accept oxygen
inputs directly from the Delta F Oxygen Cell. There are three steps for installing the Delta F Oxygen Cell:
1. Prepare the oxygen cell for operation
2. Calibrate the oxygen cell.
3. Connect the oxygen cell to the gas line.
The Delta F Oxygen Cell is available with various types of mounting enclosures. However, the cell itself will
always look like the one shown in Figure 7 below.

1.8.5.1 Preparing the Oxygen Cell
To prepare the oxygen cell for operation, you must fill it with the electrolyte that was supplied in a plastic
bottle.
WARNING! The electrolyte contains potassium hydroxide that is harmful if it comes in contact with
eyes or skin. Consult your company safety personnel for proper procedures for handling the electrolyte.
1. Unscrew the top cover on the oxygen cell reservoir.
2. Slowly add the entire contents of the electrolyte bottle, approximately three ounces (90 ml), making
sure not to spill any on the outside of the cell. Be especially careful that the electrolyte does not come in
contact with any of the cell electrical connections.
3. Using the min/max window on the oxygen cell, check the electrolyte level. The electrolyte should cover
about 60% of the window (see Figure 7 on page 12). The cell is now ready to be connected to the gas
line.
4. Replace the top cover on the oxygen cell.
Note: After you add the electrolyte, DO NOT add additional electrolyte to the reservoir. If the level falls below the
minimum level, refer to “Delta F Oxygen Cell Electrolyte” on page 87 to replenish the cell.
5. Calibrate the oxygen cell as described in “Calibrating the Delta F Oxygen Cell” on page 89. After you
calibrate the oxygen cell, connect it to the gas line as described in the following section.
1.8.5.2 Connecting the Oxygen Sample System to the Gas Line
To connect the oxygen sample system to the process line, attach a 1/8 inch O. D. (outside diameter) tube to the
1/8 inch sample gas inlet fitting, using a Swagelokor equivalent mating connector. Avoid using plastic or
rubber for any tubings or fittings which are included in the inlet gas lines.
WARNING! Do not connect the oxygen cell outlet to flow restricting devices, pressure lines, or
vacuum lines. Pressure differentials across the oxygen cell sensor in excess of 1 psig could be harmful or
damage the cell.
If the gas being monitored does not create a safety hazard, vent it to atmosphere at the sample system outlet. If
venting the gas to atmosphere causes a safety hazard, vent the gas to a safe location. Make sure the venting
system does not create a back pressure on the oxygen cell.
Note: The vented sample will not be corrosive if you install and operate the cell properly.

1.9.3 Connecting Moisture Probes
The moisture.IQ uses M-Series and Moisture Image Series probes to measure moisture. If you need to connect a
different probe type, please contact our technical support department. If you ordered one or more M-Series
probes with the moisture.IQ, BHGE has entered the necessary probe setup data on a pre-assigned channel.
IMPORTANT: See the Calibration Data Sheets, shipped with the probes, to connect the probes to their
corresponding channels. If a probe is connected to the wrong channel, the meter will display
incorrect data.
Probes are identified on the Calibration Data Sheet by a serial number. The serial number is also engraved on
the hex nut of the probe, as shown in Figure 11 below.
Probe Serial Number
Figure 11: Moisture Probe Serial Number
The Moisture Image Series probe does not require any pre-programming, because it stores all the necessary
setup data in its electronics module. Therefore, you can install a Moisture Image Series probe on any
available channel. After you install the probe, you must activate the probe on the installed channel, as
described in “The Probe Configuration Screen” on page 60. Proceed to the following sections to properly
connect your moisture probes.

Chapter 1. Installation
1.9.3.1 M-Series Probes
M-Series probes are primarily used for moisture measurement, but they can be used to measure temperature
as well. If ordered, an optional temperature thermistor is included in the moisture probe and requires an
additional connection.
If the M-Series probe does not have a thermistor, then you may use a two-wire shielded cable with a
bayonet-type connector to connect the probe to the electronics unit. If an optional thermistor is installed, then
use a four-wire shielded cable with a bayonet-type connector to connect the M-Series Probe to the electronics
unit. The M-Series Probe may be located up to 600 m (2000 ft) from the moisture.IQ.
Before making the electrical connections, connect the cable to the probe by inserting the bayonet-type
connector onto the probe and twisting the shell clockwise until it snaps into a locked position (approximately
1/8 of a turn). Wire the probe cable per the wiring diagram in Figure 12 below. The M-Series terminal block
on the back panel of the moisture.IQ (see Figure 13 on page 18) also notes the corresponding color from the
probe cable.
