Harwil Corp’s Q-5 (brass flow) or Q-5SS in (316 Stainless Steel) switches offer heavy-duty, proven long-term performance for high-volume fluid flow. Adaptable to a wide range of pipe sizes and flow rate set points using variable shaft lengths and targets, they use a 15-amp SPDT switch or can be fitted with a ‘dry’ circuit SPDT Gold Cross bar switch for computers. Installation can be vertical or horizontal. Fitted with a NEMA 4 cover, they perform reliably in municipal water supply systems, sewage treatment plants and large-scale irrigation systems.www.harwil.comHarwil@harwil.com
