TM
1000 – Ultrasonic heat meter
Mounting Depending on the design, the heat meter is
installed either in the supply or return line as
indicated on the data plate. The heat meter
is to be installed so that the direction of flow
corresponds to the direction of the arrow on the
flow sensor.
Ensure that the flow sensor is always filled with
liquid on completion of installation. Straight
inlet/outlet pipes (calming sections) are not
required for the flow sensor. The heat meter
can be installed in both horizontal and vertical
pipe sections, but every time so that air bubbles
cannot collect in the flow sensor. For low flow we
recommend to mount the flow sensor tilted 90°
into the pipe.
Make sure the heat meter is installed
sufficiently far away from possible sources of
electromagnetic interference (switches, electric
motors, fluorescent lamps, etc.).
For cooling application and for medium
temperatures more than 90° C, the calculator
must be mounted on the wall at a sufficient
distance away from heat sources using the
holder supplied. It is recommended that stop
valves be fitted before and after the heat meter
to simplify dismantling the heat meter. The
heat meter should be installed in a convenient
position for service and operating personnel.

SONOMETER™1000’s instructions.
