These
indicators are based on the popular Rhodes 900 series. They are two sided
flow indicators lined with corrosion resistant fluoroplastic PFA and FEP.
The linings are held in place by dovetail grooves machined into the cast body,
allowing them to be used under full vacuum. All wetted parts are PFA/FEP together
with either toughened soda lime or borosilicate glass. The indicators are
available with either a spout which produces a jetting action or turbulent
flow thereby improving the viewing of clear liquids, or alternatively with
a flap. The large viewing area allows the flow, colour and condition of the
liquid to be observed and hence provides a check on product quality and consistency.
The indicators are suitable for both vetical and horizontal installation.
The inclusion of a spout allows them to be used as drip indicators to show
valve leaks, distillation or similar conditions.
