Coriolis mass flow meters patented and developed by
our company are the leading meters for precision flow measurement. And with
good performance, Its accuracy is very high, with low requirement on flow status and pressure loss.
The meters offer direct mass flow, volume flow, density, and temperature measurement
of liquids and slurries — without the need for additional manual
calculations, or estimations.
The meters are with
unsurpassed performance in even the harshest operating environments. They have
no moving parts inside, no any special mounting and low working condition requirements.
Every meter is available with stainless steel wetted parts and a wide variety
of process connections to meet your need.The
meters carry hazardous area approval for P. R. China.
Principles of Measurement
structure of Coriolis Mass Flow Meters consist of a pair of bended tubes.
The principle is to detect Coriolis force on a pair of bended tubes to measure the mass flow of the inside tubes.
force—Coriolis force would appear while meeting two conditions: (1) bended tubes vibrating
with a fixed frequenc, (2) fluid flowing in tubes.
This force was produced upon the mixture from vibrating force and flowing force
by fluid in tubes. And tubes would be wresting symmetric the center line
because the force forced. Two displacement sensors on sides of tubes detect output electric signals, handle the signal, and then get the mass flow.
