Series FS10-C Flow Switch

–––––––––––––––––––––––––––––––––––––––––––––

EASY WIRING – cover

INDEPENDENT Switch assembly

completely removable, no danger of wires interfering with operation. HIGH – (Coarse) Sensitivity Adjustment

Sizes: For pipes 1" - 6" (25 – 150mm) Series FS10-C Flow Switch provides accurate monitoring of liquid flow in pipelines servicing water systems, heating systems, air conditioning, and processing installations for industrial and commercial applications. The flow switch is designed to act as an automatic control or safety device for liquid flow. The singlepole, double-throw switch can be wired to start or stop a motor when a flow or no flow condition exists or activate an alarm when flow is inadequate. The switch then turns off the alarm when adequate flow is restored. Series FS10-C flow switches install in tee in horizontal or vertical piping.

SWITCH – Single pole, double throw

O-RING INLET ADAPTER – Threaded connection (quick paddle orientation in pipe.)

PADDLE – made of beryllium copper. Segmented and quickly adaptable for 1" (25mm) to 3" (80mm) pipe. Extended paddle also included for larger pipe size.

Features • Beryllium copper paddle • Single cover retaining screw mounted on top of flow switch • Coarse and fine sensitivity adjustment • Two electrical conduit knockouts • Easy accessibility to switch terminals • 1" (25mm) NPT connection

TWO KNOCKOUTS – Connect conduit at either side of chassis.

Paddles 3 in 1 Paddle – A segmented beryllium copper paddle is quickly adaptable for 1" through 3" pipe (25 through 80mm). The extended beryllium copper paddle, also included, is for larger pipe sizes up to 6" (150mm). Paddle length conforms to ASTM tee standards.
