The Siemens 7ME39505LB01 is an ultrasonic transit time sensor designed for clamp-on applications. This paired sensor is built to measure liquid flow accurately across a wide range of pipe materials and diameters, from 12.7 mm to 50 mm (0.5 to 2 inches). It’s suitable for use in demanding environments, including hazardous zones classified as Ex Zone 0, 1, and 2, as well as Class 1 Division 1 areas. The sensor’s robust design features a durable polyetherimide and stainless steel housing, and it operates reliably within a temperature range of -40°C to +121°C (-40°F to +250°F). Distributed by BSP Automation, this sensor offers flexibility and precision for various industrial flow measurement needs.
