Introducing RedyCompact Mass Flow Meters and Regulators- New Video

Mechanical rotometers have been a staple for flow measurement since the early 1900s, giving engineers and scientists fast and economical gas flow measurement. Sierra introduces the next generation advancements in this technology with the RedyCompact™ mass flow meters and regulators,

Watch Sierra’s NEW video to learn how this unique battery-powered digital mass flow meter, regulator or flow switch for gases offers users the ultimate upgrade to mechanical rotameters.

RedyCompact is ideal for industries that have recognized the limitations of their rotameters. As volumetric meters, rotameters are unable to measure the gas mass flow rate. The results in  poor accuracy. The RedyCompact has an easy-to-use digital interface and provides users mass flow measurements at a lower cost than mass flow meters or controllers. To bring your process or system into the digital age with minimal investment, the RedyCompact is the perfect drop-in replacement for common sight-glass rotameters meters.

RedyCompact Provides Users with:

• Drop-in replacement of outdated rotameters


• Direct Mass Flow, not volumetric, for highest accuracy & repeatability


• Lifetime no-drift sensor guarantee


• Large Touch-screen display offers intuitive navigation and automatic screen adjustment (0°/90°/180°/270°) for easy installation and visibility


• High-precision MEMS (Micro-Electro Mechanical Systems) technology utilizing an advanced ultra-stable


• CMOS (Complementary Metal Oxide Semiconductor) sensor


• Flow alarms to notify you when a flow event happens
