OPERATION: NWM PMCB  Bronze Compound Meters utilize a turbine type meter on the main flow line and a proportionately sized meter on the low flow bypass line. A change over valve controls the flow of water through the appropriate measuring device. Before the valve opens, all water flows through the low flow meter. As pressure rises the valve opens, allowing water to flow through both meters. Movement of the   measuring    elements  is transmitted   to   drive  magnets,   which   transmit  the motion     to  driven  magnets    located  within   hermetically   sealed  registers. The magnets are connected to gear trains, which translate the rotations into volume totalizators displayed on the register dial faces.
