3.6 Process conditions
3.6.1 Process temperature
− 40 °C to + 180 °C (-40 °F to 356 °F); rating plate range must be observed
3.6.2 Physical state
Liquid product (maximum density 2 kg/l)
Gaseous product (minimum density 0.002 kg/l in operating state)
3.6.3 Viscosity
0.3 up to 50,000 mPas (0.3 to 50,000 cP)
3.6.4 Gas content
The use of products containing gas is not allowed for custody transfer operations. In other applications,
the presence of gas will increase false readings. In order for the readings of products containing gas to
be valid, small gas bubbles must be homogeneously distributed in the fluid. Large gas bubbles will auto-
matically provoke extremely false readings and will shift the zero point. Thus, the extent to which readings
are false is determined by the process conditions. A rule of thumb in this regard is as follows: A 1 % gas
component will increase false readings by 1 %. The gas component is not to exceed 5 %.
3.6.5 Process temperature range
+ 180 °C (356 °F)
3.6.6 Process pressure range
According to PN16 pressure rating: 232 psig [16 bar] and PN40: 580 psig [40 bar]
3.6.7 Outlet pressure
Outlet pressure must be greater than the vapor pressure Ps (static pressure) of the measured product.
3.7 Connection to the transmitter
3.7.1 Integral mount configuration
When the transmitter is mounted directly on the sensor, no cable connection between the two compo-
nents is needed. This connection is integrated at the factory.
3.7.2 Remote mount configuration
If the transmitter is not mounted directly on the sensor, installation regulations and applicable legal stan-
dards are to be adhered to. The maximum cable length is 300 m (1000ft). See Section 11.5.2 Wiring dia-
gram on page 41 for information regarding the connection and cable specifications.
