Horizontal installation
When using a bent measuring tube and horizontal installation, the position of the sensor has to be
matched to the fluid properties!

Horizontal installation for sensors with a bent measuring tube
1
Not suitable for fluids with entrained solids. Risk of solids accumulating.
2
Not suitable for outgassing fluids. Risk of air accumulating.
Zero point adjustment
All measuring devices are calibrated with state-of-the-art technology. The zero point determined in
this way is imprinted on the nameplate of the device. Calibration takes place under reference operating
conditions
ä
13. Consequently, the zero point adjustment is generally
not
necessary for Promass!
Experience shows that the zero point adjustment is advisable only in special cases:
• To achieve highest measuring accuracy also with very small flow rates.
• Under extreme process or operating conditions (e.g. very high process temperatures or very high
viscosity fluids).
Inlet and outlet runs
There are no installation requirements regarding inlet and outlet runs.
Length of connecting cable
Max. 20 meters (66 ft), remote version
