Sight Flow Indicators

A low cost, 'entry level' sight flow indicator with either high sensitivity spinner or ball operating from 0.7 l/m (water). The nitrile seals and nylon spinner or PTFE ball give excellent chemical resistance which is further enhanced in the stainless steel version by the use of borosilicate glass as standard. 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 horozontal plane.
