Application

The Vista ‘Spinner’ is a single sided gunmetal indicator that can be used on pipe sizes from 8mm to 25mm (¼” to 1”).  The spinner starts to rotate when flow starts and is clearly visible from distances.  The design offers low pressure losses and is suitable for installation in both horizontal and vertical pipework, and with bi-directional flows.

Applications include:

·           Pump, compressor and diesel engine protection

·           Ensuring that flow of cooling water is maintained to specialised welding equipment

·           Detecting changes in colour and condition of liquids during processing

·           Indication of air entrainment

·           Early warning of overheating, bearing or seal failure

Construction

The bodies are cast in high quality gunmental

The glass dome is held in place by a brass clamp ring and sealed with a Viton O’Ring.
