摘要： A flow meter comprising means for receiving a flow of fluid diverted from a mains supply through an inlet and supplying the flow to first fluid conveying means for conveying the flow of fluid to a flow measurement duct, the direction of the flow being reversed in said first fluid conveying means, means for generating a magnetic field across the duct, means for deriving a flow measurement from the voltage induced by said magnetic field in the fluid, and second fluid conveying means for conveying fluid from the measurement duct back to the mains supply through an outlet adjacent said inlet As the meter includes no moving parts, the lifetime of the meter can be significantly longer than that of a displacement meter having an oscillating piston.
