Model 1800 in-line flow switch features all-plastic components made of PVC, an O-ring of Viton "A," and a return spring of 316 stainless steel. Process connections are standard with 1-inch slip ports and optional adapters available in 3/4 and 1/2 inch slip as well as 3/4 and 1/2 inch NPT. The unit operates by a positive displacement principle. A shuttle housing a magnet is displaced by the liquid's flow or no flow to actuate a hermetically sealed reed switch encapsulated within the stem.

Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
