To prevent water theft, the choice of dial material is very important. The anti-theft water meter dial cover is divided into plastic and glass, and the two kinds of water meters that seem to be similar in appearance are very different in the performance of anti-theft water.
The plastic dial cover material is light, low-cost, and easily damaged.
The glass dial cover of the water meter is effectively resistant to tampering. and more durable.

But which glass is better for a water meter? And how exactly does it prevent water tampering?<\/strong>

Let me conduct a comprehensive analysis from the material performance, tampering methods, and the anti-theft scheme, and you will uncover the secrets of the anti-theft<\/em><\/em> water meter dial.<\/em><\/p>\n\n\n\n

Plastic Water Meter Dial<\/strong><\/h2>\n\n\n\n

Plastic material: Plexiglass -PC polycarbonate, PMMA polymethyl methacrylate
Features: <\/strong>The Plastic water meter dial must use high transparency plastic to see the reading of the water meter.

PMMA<\/strong>, as the most transparent plastic, is widely used in lamps and lanterns, so it is also fully capable of being used on water meters.
PC <\/strong>material is very widely used, but also has a high light transmittance, the price is cheaper than PMMA, and the impact strength is higher than PMMA.

PC material is the most common material for water meter plastic dial<\/span><\/strong>, with the highest comprehensive cost performance.

Disadvantages: <\/strong>But all plastic, even after special treatment of PMMA and PC,  still fall short of tempered glass water meter in terms of its high temperature resistance and impact resistance, anti-ultraviolet capabilities. Moreover, they do not offer anti-theft functionality.<\/p>\n\n\n\n

Glass Water Meter Dial<\/strong><\/h2>\n\n\n\n

Glass material: Inorganic glass – high borosilicate glass, tempered glass
Glass water meter dial is a better choice of water meter material. But not regular glass. \u200b

Ordinary glass has low strength and is easy to break. Poor thermal stability, drastic temperature changes will lead to glass breakage. Low hardness level, the surface is easily scratched.<\/p>\n\n\n\n

Borosilicate Glass<\/strong> Water Meter Dial<\/strong><\/h3>\n\n\n\n

Glass with a high boron content, due to differences in its molecular structure:<\/p>\n\n\n\n

Advantages:<\/strong><\/p>\n\n\n\n

    \n
  1. The thermal stability is very high, and the linear thermal expansion coefficient is (3.3\u00b10.1)\u00d710\u207b\u2076\/K, which is about one third of ordinary glass. High borosilicate glass will not cause the glass to break when the temperature changes dramatically.<\/li>\n\n\n\n
  2. High surface hardness, strong scratch resistance.<\/li>\n<\/ol>\n\n\n\n

    Tempered glass<\/a> is produced by subjecting ordinary glass to heat treatment.
    Advantages:<\/strong><\/p>\n\n\n\n

      \n
    1. Tempered glass\u2019s impact resistance is 3 to 4 times that of regular glass.<\/li>\n\n\n\n
    2. The bending strength of tempered glass is 4 to 5 times that of regular glass.<\/li>\n\n\n\n
    3. Thermal stability can reach up to 300\u00b0C(572\u2109).<\/li>\n<\/ol>\n\n\n\n
