Then, the horizontal bar at the top of the vertical bar is rotated to make it parallel to the holes on the surface of the protection plate, and the fixation of the telescopic cover is released. Then, the telescopic cover is extended downward to shield the electromagnetic flowmeter body, so that the electromagnetic flowmeter body can be prevented from being exposed to rain and snow for a long time, rusting of the electromagnetic flowmeter body can be prevented, and the service life of the electromagnetic flowmeter body can be increased.

Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual Figure 1 - Figure 7 , an electromagnetic flowmeter that is easy to clean, comprises an electromagnetic flowmeter body 1, a measuring pipe 2 is arranged at the bottom of the electromagnetic flowmeter body 1, a bottom plate 3 is arranged at the bottom of the measuring pipe 2, through pipes 4 are arranged on both sides of the measuring pipe 2, a filter assembly 5 is arranged inside one of the through pipes 4, the filter assembly 5 is used to filter the liquid inside the through pipe 4, a protective assembly 6 is arranged on the top of the electromagnetic flowmeter body 1, and the protective assembly 6 is used to shield the outside of the electromagnetic flowmeter body 1; the filter assembly 5 comprises two filter plates 51 arranged inside one of the through pipes 4, two through grooves are arranged on the top surface of the through pipe 4, the tops of the two filter plates 51 both pass through the through grooves and extend to the outside of the through pipe 4, and two row pipes 53 are arranged through the bottom of the through pipe 4; a handle 52 is arranged at one end of the two filter plates 51 and located at the top of the through pipe 4, two positioning rods 54 are arranged on one side of the two handles 52, the two positioning rods 54 are respectively located on both sides of the filter plate 51, a plurality of positioning holes 55 are arranged on the top surface of the through pipe 4, and the two positioning rods 54 are both engaged with the positioning holes 55.

[0026] In this embodiment, the implementation scenario is specifically as follows: the two filter plates 51 can be used to perform secondary filtration on the liquid entering the through pipe 4, which can reduce the amount of impurities entering the measuring pipe 2, and can achieve the effect of preventing a large number of impurities from affecting the measurement of the electromagnetic flowmeter body 1. When it is necessary to clean the filter plate 51, first pull one of the handles 52 to separate the fixing rod on one side from the fixing hole on the surface of the through pipe 4, and drive the filter plate 51 to move out of the through groove. Since the inner wall of the through pipe 4 and the limiting plates on both sides of the filter plate 51 are symmetrically installed, and the surface of the filter plate 51 rubs against the limiting plates inside the through pipe 4 when it moves, so as not to Only the impurities on the surface of the filter plate 51 can be scraped off, and the filter plate 51 can also be limited to move parallel to the limit plate. By cleaning or replacing one filter plate 51 and then cleaning and replacing another filter plate 51, continuous filtration of the liquid can be achieved, and the electromagnetic flowmeter body 1 can be avoided from being shut down and then cleaned. Moreover, since a sealing ring is installed inside the through groove, when the filter plate 51 is taken out, the sealing ring can block the liquid when the liquid continues to flow, and the liquid can be prevented from overflowing from the groove. Then, by opening the drain pipe 53 at the bottom of the through groove, the impurities can be discharged from the inside of the through pipe 4.

[0027] For further information, please refer to the attached manual. Figure 1 , 35. The protection assembly 6 includes a protection plate 61 arranged on the top of the electromagnetic flowmeter body 1, a plurality of support rods 62 are arranged at the bottom of the protection plate 61, support plates 63 are arranged on both sides of the measuring pipe 2, the bottoms of the plurality of support rods 62 are connected to the surface of the support plate 63, a telescopic cover 64 is commonly arranged on the outer side of the plurality of support rods 62, and the top of the telescopic cover 64 is connected to the surface of the protection plate 61; vertical rods 65 are arranged on both sides of the telescopic cover 64, and cross rods 66 are movably arranged on the tops of the two vertical rods 65.

Secondly, when foreign objects fall from the top of the protective plate 61, the damper 68 between the bottom of the protective plate 61 and the support rod 62 can reduce the impact force on the protective plate 61, thereby preventing the electromagnetic flowmeter body 1 from being directly hit.
