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.

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.

Installation
General Considerations (Site Selection)
Superheating chamber must be installed
within 45° of vertical to front or back.
Attachment to vertical steam line is optimal.
Mounting both calorimeter and cabinet is
required. Cabinet must be mounted on a
wall. Mounting hardware is supplied.
• Use one or both sections of flex hose provided depending
on installation
• Length must not exceed 3 m (118 in.)
• Hose must run down from calorimeter assembly to cabinet
with no low spots where pools of condensate could form
Attachment to horizontal
steam line must be at
center line or above.
Connecting to top of
horizontal line may result in
elevated dryness readings.
Note: Where necessary outlet on heating chamber can be
rotated 180° to accommodate left or right cabinet position.
See instructions below (p. 11).
Unit must be installed with the following utilities nearby:
• Cooling water supply
• Drain
• Grounded power source with required voltage (alternative
grounding of unit is permissible, but grounding is required)
Ambient temperature must be 5–60 °C (41–140 °F)
Relative humidity must be 30–80%
Altitude must not exceed 2000 m (6562 ft)

Operating unit without
calibrated orifice in place
may allow high pressure
steam to enter unit causing
personal injury. Consequent
damage to equipment is not
covered by warranty.
If connecting to an existing steam line connection, outlet must
be valved.
If steam line has no connection, install ½" valved connection.
Typical Installation
Note:
• Unit is shipped assembled for vertical steam line as shown
below. Connecting to top of a horizontal line will require
changing some components as shown on following page.
• Installation is highly variable based on site requirements.
• Connections shown below are typical.
• Contact Armstrong for variations as required.
Assemble calorimeter.
For vertical or side of
horizontal steam line
• The cable connecting Harting Plug to the sensors can not be
looped.
• Avoid electro-magnetic influence.
Confirm that calibrated orifice is between
tee and calorimeter.
Rotate superheating
chamber if necessary (see
instructions next page).
Pressure transmitter must
not be installed down.
Optimal position is up.

The unit can be damaged if
steam and water supplies
are not disconnected before

After a shut-down of the unit,
condensate accumulates inside the
cabinet. In case of long term storage
the unit has to be fully drained to
avoid contamination risks.
