ABSTRACT:
A flow meter alarm device easily attached to and removed from a flow meter at various locations along the length of the flow meter. The device is compatible with flow meters which have a float for measuring flow velocity. The device preferably has two housings, extending from a third housing having a display surface, that define an area for receiving a flow meter. The extending housings are preferably drawn together by a threaded member thereby clamping the device onto the flow meter. A sensor mounted on the device, preferably an optical emitter coupled with an optical receiver, is able to detect the float. When the float is detected, a signal is produced by the device notifying that the flow rate has fallen outside a desired range. The device is adjustable to function with flow meters of various different dimensions.
