Zero point balance under operating
conditions
Devices in the CoriolisMaster series do not necessarily require
zero point adjustment. Performing a zero point adjustment is
only recommended in the following cases:
• For measurements in the lower flow range
(below 10 % of Q
max
DN).
• If particularly high accuracies are required (0.1 % or
better).
• If the operating conditions (pressure and temperature)
deviate greatly from the reference conditions (see data
sheet).
For zero point adjustment under operating conditions, make
sure the following conditions are present:
• The meter tube is completely filled with the measuring
medium.
• For liquid measuring media, no gas bubbles or air
pockets may be present in the meter tube.
• For gaseous measuring media, no liquid components or
condensates may be present in the meter tube.
• The pressure and the temperature in the meter tube
correspond to standard operating conditions and are
stable.
In case of an increased zero point (> 0.1 %), check the installation
for ‘best praxis’ and make sure that no gas content is contained
in liquids, or that there are no liquids or particles in gases.

Zero point balancing can be started either manually via the LCD
indicator or using an appropriately configured digital input.
