1. INSTRUMENT DESCRIPTION
Visual flow indicators are normally used to display the passage of liquids; moreover, there are models that are even pre-
arranged to sense gaseous fluids.
Visual flow indicators of the free-passage type are designed to be fitted in whatever position within the system, both
vertically and horizontally, and with a two-directional flow.
- “model
SLE
”: free-passage sight glass;
- “model
SCE
”: free-passage sight glass with chain to further improve the fluid passage display.
- “model
SBE
”: free-passage sight glass with fixed paddle to create whirlpools within the flow and further improve the
flow passage display;
- “model
SBB
”: free-passage sight glass with drip for a typical application within distillation processes;
- “model
E
”: free-passage sight glass with glass tube;
- “model
SPG
”: free-passage sight glass with threaded ring nuts;
- “model
SPV
”: free-passage sight glass with rotating impeller.
As regards visual flow indicators of the moving paddle type, the direction and the sense of the flow are well known and
shall always be respected.
- “model
SPA
”: sight glass of the moving paddle type for vertical mounting with ascending fluid;
- “model
SPD
”: sight glass of the moving paddle type for vertical mounting with descending fluid;
- “model
SPO
”: sight glass of the moving paddle type for horizontal mounting with fluid rate measurement.
There are another two types of sight glass that are used as visual windows for mounting on vessels:
- “model
SSR
”: with circular-shaped;
- “model
SSL
”: with oval-shaped.
Finally, there are also two models in which display of passage to liquids, isn’t carried on directly from the porthole, but
through a returned indicator (these two models are suitable for hogh pressures and/or temperature):
- “model
CV-TM
”: sight glass with valve type body;
- “model
SPO-TM
”: sight glass with body “SPO” model.
