3.4 Measuring Ranges
• Measuring ranges will be manufactured and calibrated
according to the individual customer specifications.
•
To order following information are required: Medium,
pressure, temperature, measuring range, viscosity and
density.
4 Assembly and Operation
4.1 Assembly Instructions
•
Make certain the fitting is suitable for the relevant ap
-
plication. The fitting must be suitable for the operating
conditions of the pipeline system (medium, concentra
-
tion, temperature and pressure) as well as the relevant
ambient conditions.
•
Check the fitting for transport damage before installing
it. If the fitting is damaged do not install it.
•
The planner, the construction company or operating
company are responsible for the positioning and instal-
lation of the fitting. Planning and installation errors can
adversely affect the reliable functionality of the fitting
and may represent a significant potential for hazard.
•
After the fitting is installed perform a tightness and
function check.
4.2 Tools Required
The tools required for installation and assembly are not
included with delivery.
4.3 Connect Flow Meter
•
The flow meter must be connected to the pipeline so it
is free of mechanical stress.
•
The flow meter has a female thread (ISO, DIN,
ANSI) and can be connected with various connecting
elements of the
em
technik system.
•
Observe the flow direction from the bottom to the top.
Cylindrical thread
Conical thread
Sealing is provided by a sealing collar for
Cylindrical threads (G, M or UNF).
A version with an O-ring is also possible.
Sealing is provided
by the thread itself
for Conical threads
(NPT).
Sealing Collar
O-Ring
Thread
• Each thread must always be connected with the same
thread type.
•
If a plastic fitting is used in combination with a metal
-
lic male fitting, additional sealing with Teflon® tape is
recommended.
5 Commissioning
5.1 Precondition for Commissioning
• Protect against leaks: Take protective measures
against exceeding the maximum permitted pressure
due to possible pressure surges.
•
Check the tightness and function of the fitting.
•
In new systems and after repairs, flush the line system
to remove foreign materials.
5.2 Operation
The series 4Z flow meter has an integrated fine regula
-
ting valve. Turn the handwheel clockwise to reduce the
flow. Turn the handwheel counter-clockwise to increase
the flow.
5.3 Reading the Measured Value
•
The position of the float in the metering tube corre
-
sponds to the volumetric flow of the medium.
• Parallax-free reading: Look over the top edge of the
float and read the measured value on the scale.
