TW Series Trailing Wire Flow Switch

Kelco
Overview

The TW trailing wire flow switch is available in two basic models, an all Polypropylene version and a Polypropylene / 316 stainless version. Both versions are available with either a ¾" or 1" male process connection in either BSPT or NPT. In addition, both versions are also available with either a Single Pole Double Throw (SPDT) microswitch for general control circuit applications, or with an SPDT reed switch, suitable for low Voltage PLC and telemetry applications. The electrical module of the TW flow switch is completely separate from the process connection and wet end of the switch. The wet end assembly and the electrical module lock together with a single externally accessible screw. This feature allows the flow switch to be disassembled and unscrewed from pipework without the need to disturb electrical wiring. A unique feature of the standard TW flow switch is its built in manual override. This allows the flow switch to be switched on at any time at the press of a button regardless of lack of flow. Using the manual override allows the system to be manually started at any time by simply pressing the button. It also makes the testing and commissioning of systems very simple. Please note: when supplied with a reed switch, no manual override is included in the TW flow switch. The TW trailing wire flow switch is available with wire sensors in various lengths from 50mm to 300mm. The required wire length must be specified when ordering. The optimum wire length for a specific application can be obtained using our online calculator.
