SI6700 IFM Flow Meter – SIR11ABBFPKG/US-100-IPF

The IFM SI6700 is a hygienic flow sensor designed for liquid and gas flow monitoring in the food, beverage, and sterile process industries. With a G 1 Aseptoflex Vario connection, high-temperature tolerance up to 140°C for SIP, and adjustable switch point via pushbutton, it ensures reliable flow detection in hygienic and washdown environments. Its robust IP69K design and fast response time make it ideal for clean-in-place (CIP) installations.
