Precautions of electromagnetic flowmeter
The electromagnetic flowmeter needs to confirm
the installation distance before installation. The conventional straight pipe
section requirement is 5D behind the front 10D.There are different requirements
for the case of bends and valves. pipe flange welding Install the flowmeter
after completion.
The measured fluid direction must be
consistent with the flow direction of the flow meter. Measuring the fluid in
the pipeline must be full. The plug-in electromagnetic flowmeter cannot be
tilted up to 15o.
It is recommended that the installation
position be at the rear end of the pump outlet to avoid the bubble stay. Do not
install at the inlet front to avoid negative pressure inside the pipe. It is
recommended to install a shut-off valve downstream.
In order to ensure the stability of the
flowmeter, reliable grounding to avoid interference, should be avoided in the
vicinity of electrical appliances that are prone to magnetic field
interference, and to avoid vibration of the pipeline, plastic pipelines must be
grounded.
