(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.
(3) The Coriolis force mass flowmeter measurement accuracy is high, up to + 0.1%~ + 0.2% R; And wide range ratio at maximum of 1: 100.
(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) Tianjin U-ideal Instrument 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.
High precision of CMF series of Coriolis force mass flowmeter is mainly used to measure the instantaneous mass flow rate and cumulative mass flow, instantaneous volume flow and cumulative volume flow, at the same time also can display the medium temperature, medium density or concentration. It is mainly suitable for the following industries:
High precision CMF series of Coriolis force mass flowmeter can also be used as a densitometer, concentration meter. At the time of the flow and temperature measurement, can measure the density of the medium, the concentration of the solution and the mixing parameters such as the concentration of the two liquids respectively.
For example: Syrup concentration (sugar) measurement in sugar mill, alcohol content measurement in brewery; Mortar flow, temperature and density measurement of Solar silicon wafer wire cut machine; Limestone slurry density measurement; Red liquid concentration measurement in sewage treatment plant; Lead plant pulp density measurement; Iron ore pulp density measurement, copper plant pulp density measurement, sand (sediment) concentration measurement in sand-excavating ship, oil and water content measurement in oil field, etc
Tianjin U-ideal Instrument Co. Air/liquid mass flowmeter 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).
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.
Temperature measuring: Platinum resistance Installed on the sensor vibration pipe can indirectly measured the temperature of the medium.
