CM Series Coriolis Mass Flow Meters
for Liquids and Gases
Mass Flow Meter SummaryThe CM Series mass flow meters
utilize industry's well recognized high accuracy standard, Coriolis
technology. The core operating principle of this technology is that
fluids flow through a vibrating tube which then causes a deflection
of the flow tube proportional to mass flow rate. It is suitable for
use with liquids, gases and slurries. Models are available that will
measure mass flow, volumetric flow, temperature and density.
Unaffected by variations in pressure, temperature, density,
electrical conductivity and viscosity, the CM Series provides
extremely accurate mass flow measurement over wide flow ranges. The
series is comprised of three (3) models which differ by their
choices in flow range, wetted parts, accuracy, pressure ratings,
density measuring, and other optional functions and features.
All three utilize a universal, full-featured transmitter, the model
CT, which can be mounted integral with the sensor element or remote
mounted up to 1,000 feet [300 m]. The extremely rugged, NEMA 6P
[IP68} rated transmitter has options for a built-in digital display,
tamper-proof custody transfer software and Profibus-PA digital
communications.
