The HD1K and HD2K Flow Switches are the latest innovations in flow switching technology. With nominal pipe sizes from 8mm to 25mm, these switches can handle flows from 0.1 to 80 liters per minute. The BSP threaded connections make installation a breeze, and the high pressure rating of 200 bar means that these switches can be used in even the most demanding applications. Plus, with the optional visual displays, you can keep track of your flow rate even when it's inconvenient or impossible to access the switch itself. And for extra peace of mind, the ATEX option is available for use in hazardous environments.
