Installation notes
Information!
All instruments are carefully checked for proper function before shipment.
On receipt, immediately check the outer packing carefully for damage or
signs of improper handling.
Report damage to the carrier and your local sales staff. In such cases, a
description of the defect, the type and the serial number of the device is
indicated.
Unpack the unit carefully to avoid damage.
Check the delivery against the packing list for completeness. Check the
name plate, if the delivered flow meter according to your order. Check that
the correct voltage supply is specified.
Special requirements VdS: The version with rolled grooved ends may only
be used in combination with VdS-approved pipe couplings manufactured
by Anvil (all Gruvlok mechanical grooved couplings), Jinan Meide (cast-
ing couplings type 1G), Minimax, Modgal, Tyco (Grinnell Mechanical and
G-Fire steel IPS couplings) and Victaulic (except pipe couplings of the type
"Style 77").
3.4 Installation instructions
In general, the measuring principle is independent of the flow profile.
The ideal installation location is in a pipeline with a sufficiently straight section of pipe in
front of and behind the measuring point. An inlet of min. 5 x DN and an outlet of min. 2 x DN
is required. Where non-stationary vortices extend into the measuring zone (e.g. following
elbows, tangential inlets or a half-open valve in front of the sensor), measures to normalise
the flow profile are required. Here suitable measures include:
»
Enlarging the inlet and outlet sections
»
Use of flow straighteners
»
Reduction of the pipe cross section
