Alicat Scientific Whisper mass flow metersAlicat Scientific “Whisper”-Series digital mass flow meters and controllers accurately and rapidly measure or control the mass flow rate, volumetric flow rate and pressure of process gases with minimal effect on the process itself. The Whisper Series features extraordinarily low pressure drops, as low as 3.6 mbar (0.052 psi) at full scale, or 0.018 mbar when fully turned down (200:1 turndown). Low pressure drop means minimal system impact, resulting in faster mass flow measurement (<10 ms) and control (<50 ms typical). At their heart is a patented, internally compensated, laminar differential pressure measurement technology that yields linear results over a very wide flow range. Alicat backs every mass flow instrument with generous customer support, including free technical phone support, prompt recalibration service and a lifetime warranty.
