Description and specifications
Harwil Q-10N and Q-10VCR Flow Switch
One body, enormous range.
The Harwil Q-10N (Noryl) and Q-10VCR (Fortron) run from 0.7 GPM in 1 inch pipe up to 1025 GPM in 16 inch pipe. Three factory adjustable parameters, target area, target length and target stiffness, are what let a single design cover that spread. It responds to fluid flow only, independent of line pressure and temperature.
| Minimum Flow | 0.7 GPM in 1.0 inch pipe |
|---|---|
| Maximum Flow | 1025 GPM in 16 inch pipe |
| Pipe Size | 1 inch and up |
| Line Pressure | 250 psig at room temperature |
| Temperature | 200 F continuous |
| Pressure Drop | Typically less than 1.0 psig at normal flow |
| Max Flow | May be five times normal flow |
| Q-10N Body | Noryl |
|---|---|
| Q-10VCR Body | Fortron |
| Paddle | 18 paddle options, 1 inch through 10 inch pipe |
| Switch Type | Reed switch, NO, NC or SPDT |
|---|---|
| Switching | 5 VDC to 240 VAC |
| Cable Options | No cable, 2, 4, 6, 8 or 10 ft |
| Certification | UL Component Recognized, file E85349 |

How does one switch cover 0.7 to 1025 GPM?
Three factory adjustable parameters, target area, target length and target stiffness, are set to match the pipe size and flow rate you order.
NO, NC or SPDT?
All three reed switch configurations are available. NO closes on flow, NC opens on flow, and SPDT gives you both contacts.
