Instrument installation
Choosing the correct installation location and adopting the correct installation method is the key to using
the electromagnetic flow meter. If the installation is wrong,
Not only will it affect the measurement effect, it will also affect the measurement accuracy, it will also
affect the life of the flow meter, and even damage the flow meter.
1. Installation location selection
In order to make the sensor work reliable and stable, the following requirements should be paid attention
to when choosing the installation location:
(1) Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields (such as large
motors, large transformers, etc.) to prevent magnetic fields from affecting transmission
The working magnetic field and flow signal of the sensor.
(2) It should be installed in a dry and ventilated place as much as possible,and not in a place with
dampness and water.
(3) Avoid sun and rain as much as possible, and avoid ambient temperature higher than 60ºC and relative
humidity higher than 95%.
(4) Choose a place that is convenient for maintenance and convenient for activities.
(5) The flow meter should be installed at the back of the pump, not on the suction side; the valve should
be installed on the downstream side of the flow.
2. Installation requirements
For your correct measurement, you should pay attention to the following requirements when selecting
the location on the pipeline:
(1) The sensor can be installed on a straight pipe, or on a horizontal or inclined pipe, but the center
connection of the two electrodes is required in a horizontal state.
2) The medium should flow in the full pipe at the installation position to avoid dissatisfied pipe and gas
adhering to the electrode.
(3) For liquid-solid two-phase fluids, it is best to install vertically to make the sensor lining wear evenly
and prolong the service life.
(4) When the medium at the installation position of the flow meter is not full, the method of raising the
back-end pipeline of the flow meter can be adopted to make it full.
Install flow meters at the high point and the water outlet.
(5) Modify the installation method of the pipeline: When the flow rate of the medium does not meet the
requirements, a flow meter with a smaller diameter should be used.
Use reducer pipe or modify part of the pipe to make it the same diameter as the sensor, but the front and
rear straight pipe sections must at least meet the front straight pipe section ≥10DN, straight back pipe ≥
5DN (DN is pipe diameter).
(6) The front and rear straight pipe sections are ≥10DN before the flow meter and ≥5DN at the back
end.
3. Instrument wiring
If the signal cable connected by split installation uses a customized dedicated cable, the shorter the cable,
the better.
The excitation cable can choose Yz medium-sized rubber sheathed cable, and its length is the same as the
signal cable.
Signal cables must be strictly separated from other power sources and cannot be laid in the same pipe.
The signal cable and the excitation cable should be as short as possible, and the excess cables should not
be rolled together. The excess cables should be cut off, and
Re-solder the joints.
When the cable mediates the sensor electrical interface, it is made into a U-shape at the port, which can
prevent rainwater from penetrating into the sensor.
