Super User Flow Controllers Mass Flow Controllers for the measurement and control of liquids and gases. Liquid MeasurementOur range of transit-time ultrasonic flow meters, vortex flow meters and thermal flow switches suited for the measurement of liquid flow rates quickly and accurately and they are suited for the most challenging liquid flow applications. LEARN MORE NOW Gas MeasurementEach gas flow meter in our range can be customised to your flow sensor to meet application requirements. These analog and digital gas flow meters, mass flow meters, controllers and switches are across three core technologies. LEARN MORE NOW Steam MeasurementWe have a variety of flow meter technologies for monitoring the accurate flow rate of steam, including: Vortex Volumetric and Multivariable Steam Flow Meters. LEARN MORE NOW 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.1.Wikipedia https://en.wikipedia.org/wiki/Thermal_mass_flow_meter
