Coriolis Mass Flow Meters
IntroductionCoriolis Mass Flow Meters type of CXCMFI are the leading meters for precision flow measurement. And with good reason, the meters offer the most accurate measurement available for virtually any process fluid, while exhibiting exceptionally low pressure drop. The meters offer direct mass flow, volume flow, density, and temperature measurement of liquids and slurries - without the need for additional equipment, manual calculations, or estimations.
The meters are designed for unsurpassed performance in even the harshest operating environments. They have no moving parts, and any special mounting or flow conditioning requirements. Every meter is available with stainless steel wetted parts and a wide variety of process connections to meet your every need.The meters carry hazardous area approval for P. R. China.Principles Of MeasurementThe structure of CXCMFI 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 forceCoriolis force 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 tubeswould be wresting symmetric the center line because the force forced. Two displacement sensors on sides of tubes detect the force and output electric signals. The signals regulated, mass flow directly produced.
