The wiring of the electromagnetic flow meter and the method of adjusting the flow rate

Before using the
magnetic flow meter, we need to understand two settings about this flowmeter. The first is the wiring method of the
flow meter; the second is how to adjust the flow rate.
When the electromagnetic flowmeter uses cable wiring, in order to prevent rainwater from penetrating into the sensor, when entering the electrical interface of the sensor, it is necessary to
make a U shape at the port. If the excitation cable is used, the Yz medium-sized rubber-sheathed cable can be used, and its length is the same as that of the signal cable; if it is installed
separately, the connected signal cable adopts a customized special cable, and the shorter the cable, the better. At the same time, it should be noted that the signal cable must not be laid in
the same pipe with other power sources, and must be strictly separated. It cannot be twisted together and should be placed in the steel pipe separately, and cannot be laid equally.
When wiring, it is recommended that the excitation cable and the signal cable be as short as possible, and the redundant cables should not be rolled together. The redundant cables
should be cut off and the joints should be re-soldered.
How to adjust the flow of electromagnetic flowmeter:
The electromagnetic flowmeter itself has this function, which can be manually debugged to adjust the diameter and flow rate. The specific operation steps are as follows:
First, enter the password into the electromagnetic flowmeter to enter the menu, and find the K coefficient column. For example, the K coefficient is 1.065. If you want to increase the flow rate,
adjust the K coefficient value. The larger the value, the larger the K coefficient, and the larger the flow rate at this time. Secondly, there is another way to adjust the flow rate. Enter the password
to enter the menu and find the column of caliber. For example, the caliber is DN50. At this time, if you want to increase the flow rate, change the caliber DN50 to DN65. Naturally, its flow rate is
larger than that of DN50. . At the same time, it should be noted that the size of the flow should not be moved by the staff. If the parameters inside are moved, the electromagnetic flowmeter will
be inaccurate.
The above is the wiring method of the electromagnetic flowmeter and the method of adjusting the flow rate introduced by CIXIFM winny. If you have any questions,
