The meaning of IP level of large diameter ultrasonic water meter
The large-diameter ultrasonic water meter is an all-electronic measuring instrument for measuring the user's water consumption. It has a delicate appearance and a high degree of protection. When it comes to the protection level, many people are curious about the IP level. What does it mean? Today, I will briefly introduce the protection level of the large-diameter ultrasonic water meter.
Like other electronic water meters, the large-diameter ultrasonic water meter reaches the national standard IP68 level, which can be dustproof and waterproof in all aspects and has a very high protection level. Under normal circumstances, the protection level of large-diameter ultrasonic water meters is represented by IP, which means Ingress Protection, and two Arabic numbers are usually followed by IP. The larger the number, the better the protection level.
The numerical value in the front row after the IP generally represents the dustproof level. 0 means no protection; 1 means can effectively prevent the invasion of large solids; 2 means can effectively prevent the invasion of medium-sized solids; 3 means can effectively prevent the invasion of small solids; 4 means can prevent the invasion of solids over 1mm; 5 means can prevent Accumulation of harmful dust; 6 means that all dust violations can be prevented.
The number in the row behind the IP generally represents the waterproof level. 0 means no protection; 1 means that the shell of the large-diameter ultrasonic water meter is not affected by water droplets; 2 means that when it is inclined at 15°C, the water droplets have no effect on the casing; 3 means that water and rain drip into the large-diameter from the corner of 60° The ultrasonic water meter will not have any effect; 4 means that the liquid intruding into its shell from any direction has no effect; 5 means that the use of water flushing will not cause any effect; 6 means that it has no effect when used in the cabin; 7 means that it has no effect when immersed in water for a short time; 8 means that it has no effect if the large-diameter ultrasonic water meter is immersed in water for a long time under a certain pressure.
