Presentation

Whisper™ MW–Series Low Pressure Drop Mass Flow Meters measure mass and volumetric flow rates when there is little available system pressure, with pressure drops as low as 0.07 PSID (4.8 mbarD).

Whisper devices are built for processes with little available inlet pressure or a large amount of back pressure. These devices have a larger flow body and uniquely arranged laminar flow elements, resulting in pressure drops up to 10x lower than standard devices. Whisper instruments also utilize a much more sensitive pressure sensor package to take full advantage of the lower pressure readings.
