Advanced Mass Metering Technology

RIB Coriolis mass flowmeter provides best massflow,
density and temperature measurement performance,
and also calculate volume flow, total flow and fluid
composition in real-time. Currently it has three styles
available which are M type sensor, U type sensor and
S type sensor, Meanwhile each series has its own
compact and remote meters.

Principle

Coriolis Mass Flow Meter uses two parallel arranged
pipes which are rotated at their resonant frequency by
coils. Any mass flow passing through the tubes will
generate coriolis forces which appear whenever a
mass moves radially in a rotating system. The forces
have opposed effects on the inlet and outlet sides, they
slightly deform the pipes. The excursion of the pipes is
detected by sensors on the inlet and outlet side. The
phase shift between the rotational frequencies of both
pipes are proportional to the mass flow rate.
