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! High voltages present inside equipment.
• 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-3 is intended to replace manual testing of
pure steam and provide real-time data proving that steam
quality meets applicable requirements.
Advantages over manual testing are:
• Improved safety
• Ease of use
• Reduced time per test
• Reduced cost per test
• More accurate and objective results
• Ability to trend data over time
Steam QM-3 is set up and calibrated to test for parameters
defined in EN285 standard. It performs three tests:
• Calculating dryness
• Calculating superheat
• Quantifying non-condensable gases (NCG)
(NCG measurement is performed first. If it is within range,
dryness and superheat measurements will be performed.)
Data from Steam QM-3 can be recorded using a data historian with Modbus
output (see appendix three on p. 29 for connection information.)
Armstrong strongly recommends that the Steam QM-3 unit be installed in one location and
not used for checking multiple steam outlets.
It is possible to use one unit for multiple locations and it could be installed for portability at
customer's preference. Note however that:
• Calorimeter assemblies and cabinets are matched sets and are not interchangeable.
• Moving both calorimeter and cabinet to alternate locations as a unit is preferred.
• If one cabinet is connected to a different calorimeter, it must be recalibrated prior to use.
Armstrong reserves the right to make design or
specification changes without notification.
Materials of construction comply with all
standards known at the time of manufacture.
