Tornatech - GT-FluxFP
INSTALLATION AND MODE OF OPERATION
The installation can be in any line routing - horizontal to vertical - place (fig. 6). However,
it is important to ensure that the flow direction of the arrow marked on the device and
corresponds to the differential pressure sampling tube (fig. 9/10, pos. 7) is in the horizon
-
tal position.
For attachment of the bypass meter, sufficient clearance must be provided. Important for
the compliance of the measuring tolerance is the central mounting of the pipeline. The
center offset must not exceed 0.5 mm.

Mounting the bypass meter
The bypass meter is only compatible with the delivered orifice plate. Please make sure
that the serial number of the orifice plate and the bypass meter are similar before installa
-
tion. Before loosening the cap (fig. 9/10, pos. 10), the pipeline must be emptied to prevent
the escape of liquids. The meter is plugged and screwed with a nut (fig. 9, pos. 9).
It must always be mounted vertically so that the float (fig. 9, pos. 4) can move freely in
the tube. About foreign bodies that have come behind the filter must be removed (see
7.2). The tightening of the nut or the cap should be done by hand as possible. The threads
must - for example be slippery - by fat. To avoid air strikes, the tube should be slowly filled
with water.

Mode of operation
The orifice plate flowmeter GT-FluxFP consists of an orifice plate (fig. 9/10, pos. 1) for
stationary installation and a portable bypass meter (fig. 9, pos. 2). The bypass meter con
-
tains a conical glass tube (fig. 9, pos. 3) with float (fig. 9, pos. 4). The water flows vertically
from top to bottom through the flow tube at the upper end of a side panel (fig. 9, pos. 5) is
arranged. A filter (fig. 9, pos. 13) at the inlet largely prevents the ingress of foreign bodies.
Inlet and outlet port for the bypass to be measured are arranged concentrically, so that
an easy to combine with the stationary primary element.
