Description
The TW26-S and TW26-SS trailing wire flow switches are heavy duty flow sensors that use a flexible stainless wire rather than a conventional paddle to sense fluid
flow. They are suitable for sensing flow in open discharge applications or in pipes of any diameter from 25mm upwards. The flexible stainless wire sensor offers
major advantages over conventional paddles when used in situations where solids or semi-solids are present, such as in sewerage pumping applications. They are
also suitable for use in slurry and mining applications and in many normal pumping situations where the flow velocity is high and conventional paddles are
unsuitable. The TW26 trailing wire flow switch is available in two models, an all Polypropylene version, designated TW26-S and Polypropylene / 316 stainless
steel model TW26-SS. Both models are identical with the exception of the stainless body. The standard all Polypropylene switch is suitable for most applications
where static or dynamic pressures are less than 18 Bars. The stainless version can safely tolerate pressures to 100 Bars. The TW26-SS has the advantage of higher mechanical strength and finds application in fire prone or vandal prone areas.
