Installation in large pipes
The flowmeter can be installed between two reducers as shown. At 8° reducing angles the
below pressure drop curve applies.
Delta-P example:
A water flow velocity of 3 m/s (V) in a sensor with a diameter reduction from DN 200 to DN
100 (D
1
/D
2
= 0.5) gives a pressure drop of 9 mbar.
L2: Min. 10 x pipe diameter

Insulation
Both versions can be insulated.
We always recommend insulation of sensor in the compact or remote version. For compact
versions the insulation can prevent heat transfer to transmitter.

Transmitter installation (compact/remote versions)
The transmitter is packed separately - ready for plug-in into base part.
There are two mounting versions of the transmitter (as shown in figures below):
●
remote transmitter
●
