The general purpose liquid flow switch is an ideal choice for a wide range of relatively clean water and chemical solutions with non-coating and/or crystallizing characteristics. Media examples include deionized water and sulfuric acid. The 1A relay provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. The short sensor is intended for use in pipe from 1/2” to 1-1/2”; the long sensor is applied in 2” and up.

Ordering Notes 1) To special order a 25’ (7.6m) or 50’ (15.2 m) sensor cable, place the cable length
at the end of the part number (ie: FT10-1305-25’). 2) Select the short sensor for use with pipe sizes from 3/4”-1 1/2” (D25-D50) and
the long sensor for 2” and higher (D63 up).
3) Select the Pulse-Point fitting to dampen the pulsating flow of liquid metering pumps. Order the FT50-1000 (PP) fitting or the FT50-5000 (PVDF) fitting. The FT50 is compatible with the short NPT flow switch.
4) The Metric sensor is offered with straight G threads on the sensing side and conical Rp threads on the cable side of the wrench flat. 5) The straight G thread version seals with an included Viton®
