Overview
The Flow Meter DFM 2000 is a handheld thermal-mass flowmeter engineered for accurate inlet flow measurement in inhaler testing systems. It delivers both volumetric and standard calculation modes and integrates temperature and pressure sensors for corrected volumetric flow.

Product summary

• Accurate flow-rate measurement for inhaler testing applications
• Volumetric mode: calculates volumetric flow using live temperature and pressure (in-built T & P sensors)
• Standard mode: calculates flow based on preset temperature and pressure conditions
• Portable, hand-held unit; can be used in-line with supplied inlet filter for non-pharmacopoeial methods
