Product Description

1) FS80-C Flow Switch responds to fluid flow in lines carrying water, ethylene glycol, or other Non-hazardous fluids
2) FS80-C Flow Switch uses a variety of paddle sizes to respond to fluid flow rates in applications with pipe sizes greater than 1-inch trade size
3) Single-Pole, Double-Throw (SPDT) flow switch that can be wired to energize one device and de-energize another device powered from the same source when
liquid flow either exceeds or drop below the set flow rates

Features and Benefits

Maximum fluid pressure of 1.5MPa

Permits use in a wide range of pressure flow conditions.

Adjustment Flow Switch Paddle

Allows from 1 in. to 6 in. pipe application

Adjustable Flow Rate Range

Allows user select the setting according the needs of system

IP55 Enclosure

Allows use in indoor or outdoor applications


FS80-C Flow Switch

IMPORTANTFS80-C Flow Switch is designed for use only as operating controls. Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of the installer to add devices (safety, limit contrlos) that protect against, or systems (alarm. Supervisory systems) that warn of, control failure.

Use FS80-C Flow Switch in application with fluid pressures up to 1.5MPa. A typical application for FS80-C flow switch is to shut down the refrigeration commpressor on a fluid chiller system if flow stops, reducing chances of chiller freeze-ups.

IP55 Enclosures

Use IP55 enclosures of FS80-C flow switch for indoor or outdoor applications in high-humidity environments. Use this model with pipes carrying fluids at temperatures in the range of -25110℃ where fluid temperatures are above ambient dew point.

The SPDT switch on the FS80-C has color-coded terminals. Red is common, and closed to Blue upon flow increase and to Yellow upon flow decrease. See Figure 2 and Table 1 for switch action and flow rates.
