FLOW METER III. ABSTRACT A liquid meter including a freely rotatable impeller driven by a constant speed drive. Liquid to be metered is introduced as a flow against; and accelerated by; the impeller. The energy necessary to accelerate the liquid is monitored to determine liquid flow; Preferably; the impeller is driven through a magnetic coupling which facili- tates isolation of at least large portions of the drive from the liquid flow. One preferred embodiment employs a pair of spring coupled shutters with one shutter being magnetically coupled to the impeller. The displacement of the spring is dependent on liquid flow with that displacement being deter- mined by photoelectrically monitoring the relative positions of the shutters. The power necessary to maintain the drive at constant speed may also; or alternatively, be monitored to determine liquid flow.
