Water meters are used for measuring the quantity of water in residential and commercial regions. They are supported and held together by special water meter casings. This particular product comes along with a special middle casing with an inlet and outlet on either side. The water flows through this casing at high pressure allowing the meter to measure the amount. While most of the casings are made up of brass, there are recently introduced plastic casings in the market. They can withstand heavy pressure since they are made up of high-quality engineering plastics.
