4.1.2. Operational pressure of measured liquid
The standard flow-sensor versions have the following pressure ratings:
Sensor size
Pressure rating
DN 15 to DN 50
PN 40 (4,0 MPa)
DN 65 to DN 200
PN 16 (1,6 MPa)
DN 250 to DN 800
PN 10 (1,0 MPa)
Relationship between operational pressure and temperature of the measured liquid.
4.1.3.
Material of electrodes
Measurement electrodes are made of stainless steel 1.4571 (316Ti). Some special applications require
use of higher-quality and more resilient materials. We provide electrodes made of Hastelloy C276, Tantalum,
Titanium and Platinum-Rhodium (PtRh10).
4.1.4. Selection of sensor lining
The sensors are produced with linings of different materials. Selection of lining material depends on
properties of measured liquid.
Soft rubber, low aggressive liquids, -35
o
C
to 80ºC, higher content of abrasive particles
Hard rubber, low aggressive liquids, +5
to 80ºC
Special rubber for potable water, +5 to 8
0ºC
Teflon PTFE, aggressive liquids with operating temperature
–20 to +110ºC, on request –35 to +150ºC
E-CTFE, operating temperature -20 to +11
0ºC, for dimensions over DN300, on request –35 to +130ºC
