1. General
This chapter contains information relating to the reception and assembly of the ZC 17-24 and ZC 17- 48
METERS.
2. Reception
The meters are packed in cardboard packing designed for and adapted to protect the meters during transport.
However if, on arrival, the packaging appears to have been damaged, the customer should notify the carrier of
the damage and inform SATAM.
3. Operating Principle
The liquid enters the metering unit in the direction indicated by the arrows (A). The rotor assembly is set in motion
under the pressure of the liquid on the blades (3). A certain amount of liquid (5) is captured between two
consecutive blades, and measured on the part of the circular way corresponding to the biggest of the 2 radii of the
stator, and then pushed towards the outlet manifold (B). The quantity of liquid measured at each revolution (i.e.
the cyclical volume) is therefore equal to four times the quantity measured.
Accuracy is obtained through the very small clearance between the rotor (2) and the stator (1), the blades (3) and
the covers.
The curved design of the manifolds and rotor ensures a steady, non-fluctuating flow of product, resulting in very
small head loss. The rotor is supported on stainless steel bearings.
A transmission system mounted on the front of the measuring chamber transmits the rotor’s movement to a
steeple calibrating mechanism enabling meter adjustment without gear replacement. The meter register is
mounted on the calibrating mechanism.
