Gems FS-550 high-pressure metal paddle type water flow switch Brand: Gems Model: FS-550 Operating voltage: 125/250 (V) Overload current: 10 (A) Certification: CE FS-550 Series - high pressure, metal paddle type water flow switch line size :1-1/4 "and above the main structural material: stainless steel or brass Setting Type: Fixed standard FS-550 flow switch can be bi-directional flow sensor with / without flow state. There are two paddles Length can be provided. paddle should be trimmed during installation, making the switch to set the flow rate when the action when the pipeline flow rises, paddle around the axis of the switch begins. pipe dimensions without wheels much, which produces The pressure drop is less than 3PSIG. performance parameters Wetted / shell brass or 316 stainless steel 302 stainless steel spring blades 316 stainless steel wetted parts other ceramics and Teflon maximum pressure of 2000 PSIG pressure drop workpiece 3 PSIG Max. Operating Temperature - 30 ° F to +300 ° F (-34.4 ℃ to +148.9 ℃) Set point accuracy of ± 25% Max 20% Max set point deviation switch * SPDT, 20VA electrical connection No. 18 AWG, 24 "long, polymers the stopper wire standard action The following table shows the set point flow at the specified operation of the switch paddle lengths. Approximation line size marked on the paddle on. All traffic to the table of the test switch is mounted in a standard "T"-shaped fitting on the. The diameter greater than 5 "applications in the calculation of the flow rate, a full-length 5 'paddles about 0.5 feet per second at a flow rate of the switch operation. Ordering Guide - Standard selector switch type, paddle length and shell material, and then specify a similar part numbers.
