I have a project where I have a water pick-up pump that is feeding a high pressure sending pump. The high pressure pump needs to work only when water is flowing to an electric side valve. In case the pick up pumps fails, I need the system to shutdown. I was thinking about the possible solutions and technologies and I found this one on desertcart. Also, smart desertcart suggested getting a timer with this. I didn't know I'd need it but it was a good advice. It has been a while since I installed everything. System is working as expected. No issues and very good set of blades to set the flow intensity and the pipe size. Review: Me agrado el surtido de paletas; la capacidad de manejo de corriente de los contactos. Bajo perfil y para tubería de una pulgada, permitió instalación sin adaptadores el lugar apretado. ## Features - This product is used to measure the fluid dynamics of fluids passing through pipes, such as water, ethylene diluents, glycols and other liquids that do not corrode copper. - This water switch is suitable for water treatment systems, central air conditioning, water cooling units, fire systems and other fields. - This switch is made of stainless steel, and long service life. - switches are typically used in locations that require interlocking or "cut" . - When the exceeds the set value, the fluid drives the blade and the microswitch, and the SPDT can connect the circuit and disconnect other circuits. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Q5ZD8WC | | Actuator Type | Hinge Lever | | Best Sellers Rank | #209,111 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #52 in Flow Switches | | Brand Name | YWBL-WH | | Circuit Type | multi-way | | Connectivity Protocol | X-10 | | Connector Type | Screw | | Contact Material | Stainless Steel | | Contact Type | Normally Open | | Control Method | Touch | | Current Rating | 15 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (19) | | International Protection Rating | IP65 | | Item Dimensions | 3.35 x 2.56 x 4.92 inches | | Item Weight | 0.52 Kilograms | | Manufacturer | YWBL-WH | | Material Type | Plastic, Stainless Steel | | Model | YWBL-WHy7wxqc2410 | | Mounting Type | Surface Mount | | Number of Positions | 1 | | Operating Voltage | 380 Volts | | Operation Mode | ON-OFF | | Specification Met | Ip65 | | Switch Type | Pressure Switch, Temperature Switch | | Terminal | Spdt | | UPC | 747333419603 | | Unit Count | 1.0 Count | | Wattage | 3300 watts | ## Product Details - **Brand:** YWBL-WH - **Connector Type:** Screw - **Contact Type:** Normally Open - **Current Rating:** 15 Amps - **Item dimensions L x W x H:** 3.35 x 2.56 x 4.92 inches - **Material:** Plastic, Stainless Steel - **Operating Voltage:** 380 Volts - **Operation Mode:** ON-OFF - **Switch Type:** Pressure Switch, Temperature Switch - **Terminal:** Spdt ## Images ![HFS-25 1"/DN25 SPDT Contacts Water Switch, Liquid Water Paddle Control Switch 6-380V - Image 1](https://m.media-amazon.com/images/I/51b5d7gF69L.jpg) ## Questions & Answers **Q: Is this good for potable water system?** A: Parts are made of stainless steel so I don't see any reason why it could not be used for potable water. **Q: what thread size and is it NPT or G or R?** A: Npt **Q: Does it work if i want to make a circuit with 5V?** A: Yes **Q: What are the on/off flowrate adjustment possibilities of this switch and the pressure drop through the unit at (say) 8 gpm?** A: Adjustment is almost infinite.
