CMF Series Coriolis Mass Flowmeter
Description
CMF Series Coriolis mass flowmeter is designed to measure the mass
and volume flow, density and temperature of flow, and use the
gathered information for technological purposes or fiscial
transfer. Improved startup and availability with simple
commissioning and reduced risk. No moving parts result in no
maintenance. Install anywhere with no flow conditioning or straight
pipe required. The flowmeter is used as the counter of gasoline, liquefied
petroleum gas, LNG, CNG, kerosene, diesel Fuel oil, Oil water and
other liquids in the chemical, petrochemical, oil, food,
pharmaceutical and other industries and public municipal
facilities. It has U type, V type and Micro-Ben Type etc.

Principle
CMF Series 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. The resonant frequency of both pipes changes in
accordance with the density of the medium. This effect determines
the density. Using one sensor density and temperature can also be
measured.
The extent of deformation of the pipes depends on temperature.
Therefore the temperature is measured for compensation purposes.

Application
CMF Series Coriolis Mass Flow Meter can measure the mass and volume
flow, density and temperature of flow at the time. The Coriolis
measuring principle operates independently of physical fluid
properties, such as viscosity and density. It is a proven
technology that has been employed in a wide variety of industries
such as petroleum, petrochemical industry,
pharmaceutical industry, paper mill, food and energy, etc. The
typical applications are as follows:
Batch Control
Blending
Process Control
Filling & Dosing
Loading and Unloading
Custody transfer
Process gas measurement
