Description
The Kelco trailing wire flow switches are unique sensors that can be used in applications where conventional flow switches would fail.
Principally intended for control of data acquisition equipment monitoring influx and effluent systems, these switches are equally
useful in high velocity flows, or in any situation where liquids may contain solids or materials that would damage normal flow switches.
These trailing wire switches have evolved to meet the need for flow sensors that are capable of maintenance free performance in the
most arduous of environments. Conventional flow switches use flat paddles to detect liquid movement. Such paddles are prone to
damage if liquid velocity is high, or if the liquid contains solids of any appreciable size. The unique trailing stainless wire used in the
switch is simply deflected by high flow rates or by impact with entrained materials. Material will not build on, or tangle around the
trailing wire. With virtually no exceptions, the material being monitored will simply deflect the wire.
Applications
- Data logging of effluent flows
- River management and farm run off systems
- Conveyor belt solids detection
- Control and logging of industrial waste
- Open channel data aquisition
- Slurry pipe monitoring
- Chemical process control

- Corrosion resistant body.
- Weatherproof IP67 Housing
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.
Application
- High velocity flow sensing
- Sewerage pump control
- Slurry pump flow monitoring
- Pump dry run protection
- Data logging effluent flows
- Open channel data aquisition
- Conveyor belt solids monitoring
