Digital Mass Flow Measurement alicat.com/m Series Overview Alicat Scientific M-Series digital mass flow meters accurately and rapidly measure the mass flow rate, volumetric flow rate, pressure and temperature of process gases. At the heart of Alicat’s M-Series mass flow meters is a patented, internally compensated, laminar differential pressure measurement technology that yields linear results over a very wide flow range. This produces volumetric and mass flow data that is fully compensated for changes in pressure and temperature and corrected for the user’s STP. All mass flow meters come with NIST-traceable calibration sheets. With no internal moving parts or heating elements, the M Series is electrically efficient and insensitive to bumps or changes in orientation. Alicat backs every mass flow instrument with generous customer support, including free technical phone support, prompt recalibration service and a lifetime warranty. Alicat M-Series mass flow meters feature large integrated displays with touchpad-accessible gas selection from 30 user-selectable gas calibrations and both analog and RS-232 digital communications. Extensive product customizations are available, including Class 1, Div 2 ATEX/CSA ratings for use in hazardous environments. The M Series is available with corrosion-resistant wetted materials (MS Series), low pressure drop (MW Series) and battery operation (MB Series). Applications Alicat Scientific M-Series digital mass flow meters are used in a variety of industries, from scientific and analytical testing to manufacturing and metrology. Multi-variable measurement, multiple gas calibrations and a low 200:1 turndown ratio allow a single M-Series meter to replace several application-specific devices. Available 0.4% accuracy, 0.2% full-scale repeatability and <10 ms metering response times ensure optimal performance of gas flow processes. The M Series is available in full-scale mass flow rates from 0-0.5 sccm to 0-4000 slpm.
