Installation of arrester grounding wire of electromagnetic flow meter

Abstract: The installation information of the arrester grounding wire of the electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. For those in the industry who only know that the electromagnetic flowmeter has the function of lightning protection, but do not know how to install the lightning arrester grounding wire of the electromagnetic flowmeter, the following describes the installation method of the lightning arrester grounding wire of the electromagnetic flowmeter. *, the electromagnetic flowmeter arrester grounding wire is long. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the installation of the arrester grounding wire of the electromagnetic flowmeter. For those in the industry who only know that the electromagnetic flowmeter has the function of lightning protection, but do not know how to install the lightning arrester grounding wire of the electromagnetic flowmeter, the following describes the installation method of the lightning arrester grounding wire of the electromagnetic flowmeter. *, the length of the electromagnetic flowmeter arrester grounding wire should not exceed 1 meter, and the multi-strand copper core insulated wire with a cross-sectional area greater than 6 square millimeters. If there is no ground net nearby, a simple ground net should be made near the arrester. The method is as follows: use three flat steels or angle steels with a length of 1.5M, and drive them into the ground in a regular triangle arrangement, weld the three flat steels with flat steel bars, weld bolts at one of the corners, and then connect the arrester grounding wire. . Second, the length of the signal cable between the electromagnetic flowmeter converter and the sensor cannot be greater than 50 meters, and the signal cable must be sheathed with galvanized pipe. If the galvanized pipe is in the air, the galvanized pipe should be grounded reliably with wires, and the grounding resistance is less than 10. Third, the power supply of the electromagnetic flowmeter is 220 volts one-way alternating current, an air switch is installed in the instrument box, the arrester and the air switch are connected in parallel, and a three-way socket is connected after the wire comes out of the air switch. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
