The Sierra TM500 promises precision, speed, and the field flexibility you need to adjust gas mixes and configure meter settings to maintain optimum process efficiency. Designed for the most demanding industrial processes in facilities management, chemical plants, gas refineries, and petrochemical production, Sierra flow measurement instruments are built to last and meet your application, budget and delivery needs.
What’s new on the TM500 from 1st September 2026
Expanded velocity range up to 60,000 sfpm for industrial gas flow measurement – opening opportunities in higher-velocity applications
Tripled gas flexibility — Select from 40+ gases in the field using the Gas Mix feature without recalibration
Advanced Data Logger now standard, including:
Date & time–stamped logging
40 daily (24-hour) totals with settable contract time
7-year history of alarms and events
Power-off totalization
More installation options — Choose from 3/4-inch and new 1/2-inch insertion probe diameters.
These enhancements make the TM500 an even stronger fit for demanding applications including flare gas, waste gas, allocation, process monitoring, and more.
Sierra now offers a new 1/2-inch-diameter insertion probe option!
Designed for facilities with smaller process connections, the new probe option gives facilities a new path to upgrade flow meter technology in existing installations with smaller process connections. It gives engineers and operators more flexibility when selecting or upgrading instrumentation for industrial gas flow applications.
