mounting requirements for various parts of the flow meter
Flowmeters are Widely used in petroleum, chemical, metallurgy, light textile, papermaking, environmental
protection,food and other industrial sectors and municipal management, water conservancy construction,
river dredging and other fields. Since the flow meter is a very precise device,and especially the inside of
the device, there will be very precise components. When installing and using it, you must be careful and
operate in accordance with the requirements of the specification.
Requirements for the bypass pipe:
Usually ,Workers offen overhaul the them during the produce the flowmeter .In order to continue normal production
during the repair and it is required to install cut-off valves or shut-off valves on the front and rear pipelines of the
flowmeter, and also set bypass pipelines. And it is required that the flow control valve must be installed downstream
of the flow meter, so that it will not affect the measurement of the flow meter during the switching control process,
and all stop valves should be opened when using the meter to avoid flow instability. The phenomenon.
Requirements for straight pipe sections:
the flowmeter should be installed in a horizontal direction and the axis of the flowmeter itself must be parallel and
consistent with the flow direction during installation. It is also required that the length of the pipeline upstream of the
pipeline where the equipment is installed must be within the specified range, and the installation site must take into
account the size of the upstream and downstream pipelines.
Requirements for installation welding:
In some conditions, welding is required when installing the flowmeter. At this time, welding with a flowmeter is not
allowed. This work should be completed before installation. And the manufacturers of measuring gas flowmeters
remind you to clean up some debris left over during welding before installing, and to clean the housework with
equal-diameter pipes instead of flowmeters to purge the pipes to ensure The instrument is not used during the
process and is therefore damaged.
