28PU
- HYDROSTATIC TANK CONTENTS GAUGE MANUALLY OPERATED
SYSTEM |
Operation
The 28PU gauge uses the hydrostatic
principle of proven reliability
and simplicity, requiring no power
supply. This method requires minimum
installation time and gives important
advantages in the safe measurement
of volatile liquids. By operating
a small hand pump, fixed at the
bottom of the gauge, charges the
system with air under pressure.
The liquid is displaced from the
balance chamber at the bottom
of the tank, while excess air
escapes via the tanks vent. The
resulting pressure in the balance
chamber is indicated by the gauge
and is proportionate to the head
of liquid in the tank. The gauge
can be mounted at any position,
and may be disconnected at any
time without upsetting the calibration.
Maintenance is not normally required,
as there are no moving parts external
to the gauge.

CALIBRATION
Each gauge is individually calibrated
and scaled to customer requirements for
Rectangular, Cylindrical (Horizontal or
Vertical) tanks in litre, gallon, kg,
tonne etc.
INSTALLATION
The 28PU contents gauge can be mounted
in any convenient position up to 30m from
the tank without affecting the reading.
Installation is simply. Mount the gauge
with fixing screws and insert the balance
chamber through a 1” or 1 ½”
BSP tank boss on top of the tank allowing
it to rest on the bottom, then tighten
bush and capillary clamp. Connect the
tube to the gauge, there is no need to
empty the tank.
