A low cost, 'entry level' sight flow indicator with either a high sensitivity spinner or ball operating from 0.71 l/m (water). The nitrile seals and nylon spinner or PTFE ball give excellent chemical resistance which is further enhanced in this stainless steel flow indicator version by the use of borosilicate glass as standard.
These compact stainless steel sight flow indicators are used extensively in plant protection applications to show coolant or lubrication flow to pumps, compressors and engines.
As an added advantage the series 400's can be used in any orientation, apart from the 'ball type', which needs to be in the horizontal plane.
