Induction flow meter FMG600 series
4.1.2. Operational pressure of measured liquid
The standard versions of flow sensors have the following pressure rating:
Sensor size
Pressure rating
DN 15 – DN 300 1/2” and 12”
PN 10 (1.0 MPa) 145 PSI
4.1.3. Selection of electrode material
Standard electrodes made of Hastelloy C4. However, in special applications it may be necessary to select a
different material. On request, Omega can supply electrodes made of tantalum -TGE.
4.1.4. Sensor tube lining
Teflon
Teflon (
PTFE
) lining is a universal solution for highly corrosive liquids and temperatures ranging from -4 °F
to 302 °F (–20 to +150°C). Typical applications are in the chemical and food processing industries.
4.1.5. Compact or remote meter version?
Temperature of the liquid is lower than 122 °F (50°C): It is possible to use both, compact or remote
version. Using of the version is only question of the layout or customer wish.
Temperature of the liquid is higher than 122 °F (50°C): Must be used remote version!
To prevent electromagnetic interference via the connecting cable, the sensor and separate electronic unit
of the meter in the remote version should be located as close as possible to each other. The maximum cable
length depends on the conductivity of the measured liquid (see the following diagram). Standard cable length
is 19,7" (6 m). .
