Electronic Mass Flow Meters & Controllers

Thermal mass flow meters ("also known as thermaldispersion or immersible mass flow meters" ^1. ) measure the the mass flow rate of liquids, gases or steam directly. Procon Instrument Technology supply quality thermal mass flowmeters from Sierra Instruments. 

Sierra's range of thermal mass flow meters offer quality instruments that are flexible and accurate with long term stability with their patented no-drift DrySense mass flow velocity sensor measuring for liquid, gas and steam in heavy industrial applicaitons.
