Reduction
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

= 0.5) gives a pressure drop of 9 mbar.
L2: Min. 10 x pipe diameter
4.2.3
Insulation
Siemens always recommends insulation of the sensor in both the compact and the remote
versions. This recommendation applies to both battery-powered and mains-powered versions.
The insulation will prevent heat transfer to the transmitter (compact versions) or terminal box
(remote versions).
