Combination water meters is accurately measure the extremely wide range of fluctuating flows which occur in some installations. ?br> For example extremely polluted water that is to be found in agriculture, sewage works or waste-water treatment plants requires a particularly robust meter. ?br> This new turbine meter is designed for continuous metering of mass flow such as in water supplied to industrial facilities and city water system available size from 70mm to 300mm and meets ISO 9002. ?br> A wide range of extreme flow rates can be measured by combining a high capacity master and sensitive slave meters. Durability for high performance prevents loss water. ?br> Simple maintenance with easy access to internal parts.High accuracy and measurement stability. All parts of the measuring insert madefrom a special material resistant to wear.
