The current meter is suspended in the flow on a rod or on awire. Two types of current meter rotors are in general use: the cup type witha vertical shaft, and the propeller type with a horizontal shaft. Most typesuse a make-and-break wire contact to generate an electric pu1se'for indicatingthe revolutions of the rotor.Acoustic Model Mark VI MalaysiaAmsler 505.036GhanaCurrent Meter withSelectorFrance45350NoNoNo£368n.r.n.a.n.r.M$600/- n.a.£345 n.a.1 790 FFr n.a.n.r.n.r.1055 000h·~~T.I Recording Reported cost V>OJ ~, s-Number ,swOJ4-w => '"in~....,Analogue Digital Basic Te1e-w >,V>~operation ~~ machine form metered :::>:toz,."x'"'" '0
