1 Fix the liquid column manometer
Fix the manometer on a wall or a vertical wall with 2 screws Ø 5mm maximum.
Set the horizontality of the manometer with the incorporated level and its setting screw.
• Unscrew the pressure connection situated above the receiver and pour the
manometer fluid up to the zero point of the graduation.
If your manometer has safety connections, remove the two measure connections
of the manometer and slowly pour the manometer fluid up to the zero point of the
graduation.
• Screw the pressure connection (solid but moderated tightening). It is not necessary to
strongly tight because the connection has a o'ring seal.

• With a squeeze bulb, a pump or a pressure generator, send up the fluid up to the full
scale of the ruler (this has the effect to wet the liquid column).
• Wait 2 to 3 minutes until the stabilization of the fluid.
2 Set the liquid column manometer
After pouring the fluid up to the zero pint of the graduation (as described on step 1), it is
necessary to perform the adjustment. For that, unscrew slightly the two knurled screws and
move to the right or left the ruler to have the setting described below below (the meniscus
must be placed on the zero) :

It is recommended to use a precise level to get a better precision The precise
level must be placed above the manometer.
For proper measurements, the bubble of the
spirit level must be between the two lines.

Reminder of the reading principle on
a inclined liquid column manometer:
for all measurements, it is imperative
to read in the meniscus deep.
