The Controlotron 994P5GLMB-3 Uniflow Universal Transit-Time Flowmeter is a highly specialized, non-intrusive ultrasonic device designed to measure liquid volumetric flow rates within industrial piping systems. Utilizing advanced transit-time technology, it calculates fluid velocity by analysing the nanosecond arrival time differences between acoustic signals sent upstream and downstream. Because it features external clamp-on transducers, the unit mounts directly onto the outer wall of a pipe, eliminating the need to cut into the line, cause pressure drops, or halt active plant operations during installation. This legacy instrument—originally built by Controlotron and later supported under Siemens' SITRANS instrumentation umbrella—is widely utilized in water management, chemical processing, and HVAC industries due to its ability to deliver precise diagnostics on clean or slightly aerated liquids without contacting the process fluid.
