Safety
Icon Legend
Burn hazard! Uninsulated components upstream of cabinet may be hot.
• Do not touch when unit is working.
• Allow to cool before moving or servicing unit.
Live steam will cause burns; condensate water may cause them. Skin exposure to
140 °F (60 °C) water for only five seconds may cause a second degree burn.
This device must be installed in accordance with appropriate local, national,
and international standards, codes, and practices.
Read this manual. It contains important information.
Service must be performed by a qualified person.
Installation should always be accompanied by competent technical assistance.
Improper installation, start-up, operation, maintenance, or service may void warranty.
You are encouraged to contact Armstrong International or its local sales
representative for additional information.
Shock hazard!
• Electrical installation must be performed by qualified personnel.
• Disconnect power before performing any electrical service.
Equipment must be disposed of according to applicable environmental requirements.

General Description
Steam QM-1 is intended to replace manual testing of steam dryness and provide real-time
data proving that steam quality meets applicable requirements.
Principle of operation:
A sample of steam is taken continuously.
Steam pressure is measured.
Steam passes through a calibrated orifice and expanded to atmospheric pressure.
Steam temperature is measured.
Sample of steam is discharge to drain (atmospheric pressure).
Dryness fraction is determined according to the Mollier Diagram.
Armstrong recommends that the Steam QM-1 unit be installed in one location and not used as a portable unit.
Advantages over manual testing are:
• Improved safety
• Ease of use
• Real time results
• More accurate and objective results
• Ability to trend data over time
Data from Steam QM-1 can be integrated in a control system using a data historian with Modbus output (see appendix two for
connection information.)

Installation
General Considerations (Site Selection)
Connection to vertical steam line is optimal.
The steam sample can be taken from horizontal and vertical steam
lines, as long as the steam sampling tube is in a horizontal plane.
Connection into
horizontal steam line
must be at center line.
Ambient temperature must be 5–40 °C (41–104 °F)
Relative humidity must be 30–80%
Altitude must not exceed 2000 m (6562 ft)
Indoor Use
Pollution Degree 2
Typical Installation
By default, orifice 0.5mm is installed. For pressure below
10barg (150 psig), use the 0.8mm orifice provided.
To clean or replace the orifice, see page 19.
Power Supply
To insure accuracy the discharge tubing must discharge to atmospheric pressure.
Warning: Steam and condensate up to 320 °F (160°C) will flow from the discharge. Precautions to safely discharge the steam and
condensate must be taken.
Note: Orientation of the holes in the pitot tube have no impact on the measurement
Note: Shortening or replacing a cable will require recalibration.
Note: See page 9 for details to cut pitot tube if necessary.
The inlet ball valve is not designed to carry the weight of the assembly especially if a heavy steam discharge hose is
connected. It is recommended to support the end of manifold.
Steam line
Max. 5" (127 mm)
At first use, fill pressure transmitter tube with water.
A blocked steam discharge pipe is a safety hazard as the parts after the orifice are not designed for pressure.
