Mass Flow Meters

Mass Flow Meters measure the flow rate of gas mass based on the convective transfer of heat on the surface of the flowing gas. The components of a basic thermal mass flow meter include two temperature sensors with an electric heater between them. The heater can protrude into the fluid stream or can be external to the pipe.

Low Pressure Drop Mass Flow Meters | Whisper MW-Series
Call for price
Low Pressure Drop Mass Flow Meters - Overview

These Mass Flow Meters measure mass and volumetric flow rates where there is little available system pressure. This includes pressure drops as low as 4.8 mbarD. Whisper devices are 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 10 times lower than standard devices. Whisper instruments utilise much more sensitive pressure sensors to take full advantage of the lower pressure readings.

Low Pressure Drop Mass Flow Meters - Features
- Simultaneously measure volumetric flow, mass flow, gas pressure, and gas temperature
- Field-adjustable engineering units and STP/NTP conditions
- 98+ preloaded NIST-traceable gas calibrations
- Define and store 20 custom gas mixtures of up to 5 constituent gases
- Backlit display and control configuration
- Integrated touchpad
- Optional integrated dual flow totalisers and alarms
- Each instrument is built to meet your specific process needs
