When there is sufficient fluid through the pipe, the loop closes up between red and blue contacts.

Mounting of S6022 Flow Switch

• Mount the switch in a section of pipe where there is a straight run of at least five pipe diameters on each side of the flow switch.
• The switch should be mounted so that the terminals or wire leads are easily accessible for wiring.
• Screw the flow switch into position so that the flat of the paddle is at a right angle to the flow. The arrow on the side of the case must point in the direction of the flow.
• The switch must be mounted in a horizontal pipeline or a vertical pipeline with upward liquid flow. It is not recommended for installation where liquid flow is downwards. When mounted in a vertical pipe with the upward flow the switch trips will operate at a slightly higher flow than shown in Figure 4: “Typical Flow Rates”, due to the effect of gravity on the switch mechanism.
• All wiring connections must be made using copper conductors only.
• All wiring must be installed in accordance with the National Electric Code and local regulations

Flow Rate of S6022 Flow Switch

 

* + GPM figures are for a switch with a 6” paddle.

* For 4” and 5” line pipes, the 6” paddle is trimmed to a 4” and 5” length, respectively.

* For switching action, refer to figure 3.
