[ALCM-DT]
Smart Measurement’s ALCM-DT delta-tubed Coriolis mass flow meters use two tubes formed into a triangle shape, or delta, in a parallel arrangement. These delta tubes are vibrated at their resonant frequency by coils. Any mass flow passing through the tubes will generate Coriolis forces, which are created whenever a mass moves radially in a rotating system. These forces have opposite effects on the inlet and outlet sides, deforming each tube by a minor amount.

How Do Delta-Tubed Coriolis Mass Flow Meters Work?
The excursion of the tubes in the Coriolis flow meter is detected by sensors located at the meter inlet and outlet, and is measured as a time delay, or phase shift. The phase shift between the rotational frequencies of both tubes is directly proportional to the mass flow rate.
The ALCM-DT delta-tubed Coriolis mass flow meter’s circuitry also makes it possible to determine conversions such as volumetric flow, percent concentration, and percent water-cut.
