3.3.3
Connecting to in-house heating pipes
Designing and making calculations for a tempered heating system is generally based on the highest
heating needs ever to be expected. Pipe network sizing is based on the permitted flow velocities of
the heated media (steam, water) or pipe friction loss. The pump capacity, and thus the sizing
parameters, result from the total of the overall resistances in the heating system together with the
required amount of heated media.
Partial load operation always means an increase in the differential pressure in the overall system. In
the case of normal, non-regulated pumps, this effect is intensified by the increasing pump
characteristic. In the case of regulated pumps (
Δ
p = constant), the pump pressure is maintained
even if the total flow is reduced but is passed on almost completely to existing, still open valves or
pipe restrictions due to the greatly reduced pipe loss.

Post-connection check
Perform the following checks after completing the installation:
Device condition and specifications
Notes
Is the device damaged (visual inspection)?
-
Does the device correspond to specifications at the measuring point ?

Installation
Notes
Are measuring point number and inscription correct (visual inspection)?
-
Was the correct installation position for the heating jacket selected?
Page 13 ff.
Is safety margin kept by 20 mm (0.79") between user isolation and Sensor?
Page 13 ff.
Process environment / process conditions
Notes
Does the run of the line to the connections at the heating jacket accordingly shifted?
(seal the connections)?
Is the device sufficiently secured against vibrations (attachment, support)?
Acceleration up to 2 g by analogy
with IEC 68-2-6
The maximum pressure rating of heating system is not exceeded?
