The Rheonik Coriolis Mass Flow Meter RHM015 is perfect for extremely low flow applications where stability and accuracy are a must. With an application range starting at a few grams a minute, the RHM015L fits R&D and small pilot requirements.

Benefits :

Torsion oscillator design assures a stable and drift-free measurement with excellent signal to noise ratios
Resilient to external noise and vibration
Insensitive to pipe pressure changes
Robust tube wall thickness provides increased operational safety in abrasive applications
Long sensor life guaranteed due to low mechanical stresses in the meter mechanism
No moving parts to wear or fail
