STRAIGHT THROUGH SIGHT FLOW INDICATOR WITH SPINNER/BALL

FEATURES & BENEFITSA low cost, ‘entry level’ sight flow indicator with either ahigh sensitivity spinner or ball operating from 0.7 l/min(water). The nitrile seals and nylon spinner or PTFE ballgive excellent chemical resistance which is furtherenhanced in the stainless steel version by the use ofborosilicate glass as standard.

These compact sight flow indicators are usedextensively in plant protection applications to showcoolant or lubrication flow to pumps, compressors andengines. As an added advantage the series 400s can beused in any orientation, apart from the ‘ball type’, whichneeds to be in the horizontal plane.

STRAIGHT THROUGH SIGHT FLOW INDICATOR WITH SPINNER

FEATURES & BENEFITSThis double sided indicator is suitable for mounting in ahorizontal or vertical position. Operating over a wide flowrange it extends the duties of the smaller figure 400 intolarger applications and to higher temperatures. It is availablewith flanged or screwed end connections and with a variety of material options. The stainless steel spinnerand mounting pin give excellent corrosion resistance.

STRAIGHT THROUGH SIGHT FLOW INDICATORS - GUNMETAL

FEATURES & BENEFITSThe Figure 903 series is a two-sided flow indicatorfeaturing an integral spout that produces a jetting actionfor turbulent flow, thereby improving the viewing of clearliquids. The large viewing area allows the flow, colour andcondition of the liquid to be observed and hence provides acheck on product quality and consistency. It is suitable forboth vertical and horizontal installation. The inclusion of aspout allows it to be used as a drip indicator to show valveleaks, distillation or similar conditions.

The Figure 904 series incorporates a pivoted internal flap,which, by its position in relation to a graduated scaleplate,indicates any changes in the rate of flow of a liquid in apipeline, from a trickle to full flow conditions. The internalstainless steel flap is electropolished to improve viewing inmurky liquids. This series is suitable for both horizontaland vertical upward flows. A variety of materials areavailable as standard.
