Introduction of Coriolis flow meter
Â
(1) The Coriolis force mass flowmeter can measure the mass flow rate directly, and won't be affected by the measured medium temperature, pressure, density, viscosity. But other kinds of mass flowmeter using indirect measurement method, to measure volume flow first, and then got the mass flow rate after compensation of temperature, pressure, density.
(2) The Coriolis force mass flowmeter inside have no moving parts, high reliability; Don't need Straight pipe before and after the installation.
(4) The Coriolis force mass flowmeter have options of all-in-one type and split type, LCD, explosion-proof type, temperature insulating model. Can output analog signal 4~20mA, the frequency signal, the RS485 communication interface and Hart protocol at the same time.
(5) The Coriolis force mass flowmeter is suitable for various liquid, such as corrosive liquid, smudgy medium, suspension, two phase liquid (gas content in liquid <10% in volume, if air content big, please add air eliminator), etc.

Working principle:
The structure of Coriolis Mass Flow Meters was consisted of a pair of bended tubes. The principle is to detect Coriolis force forced a pair of tubes from inner mass flow by fluid.
A new force—Coriolis force (picture 1) would be appear while two conditions met: (1) vibrating with normal frequency in a pair of bended tubes, (2) fluid flowing in tubes. This force was produced upon synthesis from vibrating force and flowing force by fluid in tubes. And tubes would be wresting symmetric the center line because the force forced (picture2). Two displacement sensors on sides of tubes detect the force and output electric signals. The signals regulated, mass flow directly produced (picture3).
Â
Density measuring: Mediums of different density flow through the sensor, the vibration frequency of the vibration pipe is different, so can calculate the medium density by the vibration frequency.
Â
Temperature measuring: Platinum resistance Installed on the sensor vibration pipe can indirectly measured the temperature of the medium.

Jaw Crusher Working Principle
When Jaw crusher working, motor through the pulley drive the eccentric shaft rotation, from the period of hubei near, fixed jaw, and for the material such as extrusion, rolling and run multiple broken, make material from large to small, gradually whereabouts until discharge through the discharge port.
Jaw crusher applications
PE series jaw crusher is typically used as primary crusher or the first step in the process of reducing rock. They typically crush using compression. It is widely used in Mining, metallurgy, construction, highway, railroad, and water conservancy, etc.. It can process Iron ore, copper ore, gold ore, manganese ore, river stone, gravel, granite, basalt, minerals, quartz, diabase, etc...
