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.

Liquid Flow Range

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
