11. Installation
The design, test and power supply for the flow meter are based on the related regulations.
User must strictly follow the instructions to guarantee the safe operation and normal working
of the flow meter.
11.1 Conditions required to guarantee the measurement accuracy of the electromagnetic
flow meter:
The test liquid is conducting.
The measuring pipe must be filled with liquid.
The test liquid must be uniform, so as to prevent the non-uniform conductivity (which
will result in serious interference). If you need to add some chemicals dynamically, it
should be added in the downstream of the flow meter.
The electromagnetic flow meter must be well grounded. Especially in the plastic pipe,
the grounding ring must be installed in order to perform solid grounding.
The straight tube section is required to be at least 5D at the flow meter inlet (internal
diameter of the measuring pipe), and at least 2D at the flow meter outlet.
The flow meter should be kept away from strong EMI, and it should not be installed
near the large motors or transformers.
11.2 Safety Measures
To guarantee human and device safety, the instructions below must be followed:
Before selecting the location and installing the flow meter, the user should carefully
read the related parts in this manual, and consider the safety requirements for the
flow meter, related devices and machine body environment.
The flow meter installation and repair must be performed by the personnel with
some flow meter knowledge.
The flow meter sensors and pipes must be correctly installed, and the sealing must
be safe and reliable. The liquid pressure should not exceed the maximum working
pressure described on the flow meter specification.
Proper measures must be taken to prevent electrical shock accident.
The handling equipment of the flow meter should meet the safety requirements.
11.3 Inspection before Installation
Check whether the flange, lining, casing and outgoing line sleeve are damaged.
Open the box cover to check whether the wiring printed circuit is loosened or
damaged.
Check whether the model number on the nameplate is consistent with the order
information.
