Plastic Water Meter

Description

Overview
Using to measure the volume of water flowing through the water pipe.

Working conditions
◎ Water pressure: ≤1.0MPa (10bar)
◎ Water temperature: 0.1℃~50℃

Product Features
◎ This product adopts imported engineering plastic, belongs to the green environmental protection water meter, high intensity, health of shell, non-toxic, cast iron and cast copper shell substitute products, also has a cast iron shell and cast copper shell unmatched environmental protection.
◎ Product performance requirements meet GB/T 778.1-3-1996 cold water meter national standard (grade B); It has the function of anti-external magnetic field; The counting device adopts the print wheel and the combination of the pointer, which is clear, convenient, accurate and durable. It is a perfect water measuring instrument at present.
◎ The full set of products can be modified by high efficiency compound antioxidant and light stability, and can be used for long time in severe outdoor environment.
◎ Excellent frost resistance, the thermal conductivity is only 1/200 of the metal shell, which is more resistant to freezing than metal shell in the same environment.
◎ Corrosion resistant, non-scaling, long service life, can be exempted from fouling of the pipe and yellow spot, long-term use does not affect water quality.
