The TW Series 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.
