Product Description

Flow-Mon’s Spinner, the latest design of low cost, ‘entry level’ Flow Indicator. This robust indicator out performs other spinner instruments by a considerable margin. When calibrated flow indicators are not needed, this single sided indicator will satisfy most requirements within pipe sizes 8mm to 40mm.

The Flow-Mon Spinner starts to rotate once flow has commenced, this can be from as low as 0.7lpm. The exceptional ratio between maximum and minimum flow is achieved by carefully toleranced manufacture. This spinner design can be mounted both horizontal and vertical, offering bi-directional flow indication with low pressure losses.
When operators require a visual confirmation in their pipework for lubrication and coolant flow, this simple Spinner can provide a cost effective solution for plant protection.
Including one of these inexpensive fittings to pipework on a powerplant may save thousands of pounds in downtime and bearing or pump impeller replacement. Add to this the safety implications resulting from plant failure and the true benefits may be fully appreciated.
