SICK FLSE100-MK121-20SSTI Gas Flow Transmitter

The FLSE100-M 20SSTI Gas Flow Transmitter is SICK’s FLOWSIC100 ultrasonic sender/receiver module (Part No. 1042678) designed for inline gas flow measurement in FLOWSIC100 systems. In typical FLOWSIC100 configurations, two FLSE100 sender/receiver units form the measurement path and are used alongside an MCU‑N control unit to generate and process flow data, delivering accurate gas velocity and flow rate information. The FLOWSIC100 devices operate on the principle of ultrasonic transit-time difference measurement, where transmitted ultrasonic signals cross the gas stream and timing differences between upstream and downstream paths are converted into flow metrics. The 20SSTI variant represents a standard FLSE100-M configuration used as a dedicated transmitter/receiver module within the FLOWSIC100 architecture, and the process‑oriented data sheets specify two FLSE100 units (for example FLSE100-PN16/CL150) paired with a single MCU‑N controller as the typical system configuration. This transmitter/receiver unit is designed to integrate with the FLOWSIC100 hardware, offering the necessary mechanical mounting interface and electrical connections to enable seamless operation within the gas flow path. Common applications for FLOWSIC100 gas flow measurement systems include emission monitoring and custody transfer in natural gas facilities, where precise, real‑time flow data is critical for compliance and process optimization.
