Profile A certain amount of water as defined by meter body passing through makes piston move. The measuring structure records its movements. Movements times defined amount making total amount of water passed registered. Features 1. Rotary piston structure. It registers total amount of water passed in the tube by calculating how many times the piston rotates. 2. Dry and wet type are both separated from water so as to keep the registering clear. 3. Registering is stable and high-graded measurement. Easy to install. 4. Long endurance with no rotating inclination and long work life. 5. Various types available to register pure water or to be installed in any position. 6. Remote transmission device can be added upon request. 7. Different structures and specifications with beautiful appearances are available. 8. Meter bodies can be of copper, SS or plastic. 9. All technical figures are conformed with GB/T778.1~3-1996 which is equivalent to IS04064 Standard Class C. Working condition L Water temperature≤ 45º C L Water pressure≤ 1Mpa (≤ 0.6Mpa for LXH-8S). Maximum permissible error L From the minimum flow-rate (qmin ) inclusive to the lower zone of the transitional flow-rate (qt ) exclusive: ± 5%.
