CMF has more than 30 varieties of series, the main difference ia that  design innovation on  flow sensor measurement  tube ; Improve the accuracy  , reliability, performance and sensitivity of  instrument; Increase the measuring deflection, improve the stress distribution, reduce fatigue damage; Strengthen the vibration resistance interference ability, etc. Thus measurement tube appeared a variety of shapes and structure (see figure 3), this section will make some classification and discussed only from different angles.

According to the measuring tube shape CMF can be divided into bending shape and straight form.
According to the number of measuring pipeline section it can be divided into the single pipe type and two pipe type.
According to the connection method of two pipe it  can be divided into parallel and serial type.
According to the direction of flow measurement pipe and the arrangementmethod of  flow direction,it can be divided into parallel and perpendicular way.
CMF can measure mass flow directly,it has high measurement precision.
It has widely measurement range, including various kinds of liquid of  high viscosity, containing solids slurry containing trace gases, liquids, having enough in the density of the high pressure gas.
 the vibrating of measurement pipe is small, it can be regarded as the activity pieces, measuring the line unimpeded pieces and activities pieces.
To deal with flow velocity distribution is not sensitive to meet, and supreme downstream straight pipe requirements.
Measured value is not sensitive to fluid viscosity, Then  influence of change of  fluid density on the value of measurement of the values of  is tiny.
It Can do many parameters measurement, such as measuring density in the same period, then derives measuring solute concentration.
