Sierra RedyCompact Mass Flow Meters

Rotameters also known as “Sight Glass” Variable Area (VA) meters, are used across nearly every industry where economical gas flow metering and flow regulation is required. Rotameters are volumetric flow meters and only capture the gas flow volume, not gas mass flow rate. All volumetric flow meters and regulators are sensitive to gas pressure and temperature changes —a pressure change of just 1 Bar generates flow rate error of up to 50%.

We designed our RedyCompact to be the ultimate alternative. A true thermal mass flow meter, RedyCompact is for those that want the highest accuracy and repeatability and need a drop-in replacement for a Rotameter.

Battery powered, with a large touch-screen, RedyCompact is easy to read from a distance. Regulate flow rate with the highresolution valve by dialing in your manual setpoint. Two standard AA batteries give the meter months of operation. An optional Micro-USB power plug is also available. utilizing an advanced, ultra-stable no-drift CMOS (Complementary Metal Oxide Semiconductor) sensor.

The use of MEMS techniques allows both electronic circuits and mechanical devices to be manufactured on a silicon chip, similar to the process used for integrated circuits.
