TA-CMI
TA-CMI is a computer programmed measuring instrument. It is a handheld instrument for
measuring differential pressure, temperature, and flow through balancing valves in hydronic
systems. It consists of a sensor unit and a instrument unit that has been programmed with the
TA valve characteristics, which makes it possible to take a direct reading of flow and differen-
tial pressures.
The TA-CMI has two main components:
• A sensor unit which contains a piezoresistive pressure sensor, one measurement valve,
connections and rechargeable NiMH batteries. The measurement valve has a safety function
which protects the sensor from too high differential pressures.
• An instrument unit which contains a micro computer, input touch pad, LCD display and
rechargeable NiMH batteries.
The instrument and the sensor units communicate wirelessly or by cable.
= Warning – read the manual.
The TA-CMI can be cleansed with a damped cloth and a lenient cleaning-agent.

Charging of batteries
Radio frequency communication
TA-CMI uses radio frequency to communicate wirelessly between the instrument and
sensor units. Always turn off radio communication when there is risk that
TA-CMI disturbs other vital electronic devices, i.e. near medical equipment
and implanted cardiac pacemakers, in health care facilities, aircrafts, blasting
areas, areas with potentially explosive atmosperes and other areas posted
“turn off two-way radio”! You turn off radio communication by setting the radio
channel to “OFF” in the Instrument setup menu (see page 30).
Storage recommendations
• Never leave water in the sensor unit when there is a risk of freezing (i.e. in a car during
winter)!
• Storage above 40°C reduces battery life.

specified, so that the instrument will display the appropriate flow value.
If the correct media type is displayed in the Measure Valve menu the
appropriate flow value is now displayed.
If the media type displayed does not correspond to actual media type,
define appropriate media according to page 20.
13. Release the calibration button on the sensor unit.
11. When the correct valve setting is specified,
press Done.
If an error message is displayed, press OK.
The setting is automatically changed to the

using the up and down keys. Use the right key
to move the cursor to the next digit.
7. Confirm the entered value.
Define media
If the media type displayed in the Measure Valve menu does not
correspond to actual media type you have to define appropriate media
according to below.
1. Navigate to the media type line by repeatedly
pressing the down key.
Note! This section is only applicable to TA valve types STAD, STAF and TBV.
2. Open the Define Media menu by pressing
Enter.
3. Go to the Media type menu.
4. Select media type by pressing the down key
repeatedly, then pressing Enter.
If the system contains ethylene glycol or propylene glycol, enter the media temperature and the
media weight (% of glycol) according to steps 5 – 11 below.
If the system contains “other” media type you have to enter the density and the viscosity of the
media according to steps 12 – 18 on pages 22 – 23.

18. Press Done.
The appropriate flow value is now displayed.
The temperature displayed in the Measure Valve
menu is in this case without importance.
17. Confirm the entered value.
If the selected valve is any other than TA valve types STAD, STAF or TBV
and you try to set the media to anything other than water, this error
message is displayed and the media setting is automatically changed to
water. The reason for this is that the correction method that TA-CMI uses
to calculate the flow when using media types other than water, can only be
made with these valve types.
If the system contains water, ethylene glycol or propylene glycol you can stop reading here.
The appropriate flow value is now displayed.
If the system contains any other media type, enter the density and the viscosity of the media
according to below.
12. Open the Media density dialog by pressing
the down key, then pressing Enter.
13. Enter the appropriate media density, by using
the up, down and right keys.
14. Confirm the entered value.
15. Open the Media viscosity dialog by pressing
the down key, then pressing Enter.
16. Enter the appropriate viscosity, by using the
up, down and right keys.
While measuring differential pressure (and flow)
or temperature (see pages 24 – 25) you can freeze
measurements by pressing Freeze.
The measured values will be freezed, i.e. so that
you will have time to make a note of them.
Press Start when you want to restart measurement.

If you try to measure the temperature without having connected the temperature sensor, the
value will be displayed as “– – –.–”.
Save as media temperature
It is possible to save the measured temperature as “media temperature” for later valve measure-
ments. This means that the media temperature is preset when you define media for flow
calculations (see pages 20 – 21).
Save the measured temperature as media temperature according to below.
1. In the Measure Temp menu, press Functions.
2. Select “Save as media temp” by pressing
Enter.
3. Press Yes.
The measured temperature is saved and will be
used in valve measurements to calculate flow
values, until a new media temperature is specified.

Clearing faults, service and calibration
Service
If you have tried to clear a fault according to above but the fault remains, contact your nearest
Tour & Andersson office. If the unit has to be sent in for repair, please enclose a description
of the fault.
Calibration
A calibration certificate for TA-CMI is issued after the delivery control. The equipment used is
traceable to national standards according to ISO 9001 or equivalent. Customers, who want a
regular calibration of the TA-CMI can order that from Tour&Andersson AB. Please mark
“Calibration” when you order. How frequent calibration of the instrument is necessary are
dependent upon usage and if it is required according to standards. As a general rule a calibra-
tion interval of 1 year is recommended.
Clearing faults
Automatic restart
If the instrument detects a lockup condition (the keyboard is not working), the instrument
restarts itself within 5 seconds. All saved data in the instrument will be unchanged.
No radio communication between instrument and sensor units
If the “radio off” symbol is displayed at top of the LCD, start radio
communication by connecting the cable between the instrument and sensor
units (see page 8).
Note! When you connect the instrument unit via the cable to a sensor unit,
you synchronise that particular sensor unit to communicate with your
instrument unit.
Incorrect function
If the instrument works incorrectly, i.e. due to
static electricity discharge, keep the start key
depressed and within one second also press the
first function key and the left key. This makes the
instrument restart but all saved data in the instru-
ment will be unchanged.
Blank LCD
If it is not possible to see the menus in the LCD,
press the Escape key for more than 2 seconds. The
LCD contrast will increase as long as the Escape
key is depressed.
