7.7 Gas tightness
All parts are assembled together with either gaskets or O-rings,
that makes the device completely tight.
The sealing of the axle holding the tape with the mechanical
housing is ensured by a special V-shape gasket.
7.8 Gaskets
Gaskets are made in FKM (Viton) for models UTImeter Gtex.
On UTImeter Gtex Chem models, gaskets which are in contact
with the liquid are made in FFKM.
7.9 Additional Load (option)
An additional load (see Figure 7-2) on the sensing probe can be
provided for one of the following reasons. This option is available
on UTImeter Gtex Visc or UTImeter Gtex Chem Visc equipped
with the storage tube Q2 (2”) and needs valves of at least 2” size.
7.9.1 Viscous liquids (> 800 Cst)
For gauging viscous liquids the load can help the sensing probe
in penetrating the liquid and in keeping the tape straight.
7.9.2 Reference height and innage
For measuring the reference height of a tank and innages
the load allows the sensing probe to touch the dip/datum
plate.
7.10 Housing and lid
These parts are made in aluminium coated with polyamid
PA 11 (RILSAN).
7.11 Others
The tape is coiled on the axle which holds also the electronic
box and the display unit.
The axle is assembled to the electronic box and can be locked
at discrete positions by means of a stopping mechanism in the
crank. Pull the crank to free the stopping mechanism.
The storage tube is threaded to the frame.
The storage tube is equipped with a quick-connector which
fits on the HERMetic valves.
