The ifm efector U4 Series Flow Block is a process adapter designed for the installation of flow sensors into pipes with low volumetric flow rates. It offers quick, easy, and secure flow monitoring with very high overload pressure resistance. The U4 series flow block is constructed from robust stainless steel that can withstand medium temperatures from -25 to 80°C and flow ranges of 15 to 400ml/min or 80 to 2,000ml/min. These flow blocks are available with an M12 or G1/4 sensor connection, and 1/4 or 1/8in NPT process connections.
