ChapterIOverview

1.1 Working principle

This product is based on Coriolis principle.The flowtubethroughwhich themediumflowsvibrates,thus causing Coriolis effect. The sensor can calculate the massflowanddensityofthefluidbydetectingand analyzing the changes of frequency,phase difference and amplitudeof the flowtube.

See Fig. 1.

Fig.1MeasurementPrincipleofMassFlowmeter

The vibration frequency of the measuring tube of mass flowmeterchangeswith thedensityof themedium in the tube.By measuring the resonance frequency of the vibrating tube,the density of the medium can be obtained.

There is a precise temperature sensor inside the mass flowmeter,which can directlymeasure the temperature of themedium and outputit.At the same time,temperature can also be used for internal compensation flowand densitymeasurement.

·Double U-shaped measuring tube,with high sensitivity.

·The converter is equipped with high-performance microprocessor and OLED display screen，and convenientand rapid settingof the parameters.

·The converter has self-checking and selfdiagnosis functions.

·The measurement is not affected by changes in fluid density, viscosity and temperature.

·The product is not affected by installation and environment,and can maintain long-term stability.

·The installation is simple,and straight pipe section and rectification are not required.

2.6Process pressure grade

The maximum working pressure of the sensor indicates the highest process pressure grade that canbe achieved by agiven sensor.The process connection type as wellas theambient temperature and process medium temperature may reduce thislevel.

2.7 Secondary pressure-resistant enclosure

The mass flowmeter sensor enclosurecan realize secondary pressure resistance and protection,and prevent dangerous media from leaking to the external environment to cause more serious accidents.

It meetstherequirementsofGB/T20801PressrePipingCode-IndustrialPiping andGB50316Design Code for Industrial Metallic Piping.

Note:When the operating temperature is too high,the instrument needs to be depressurized for use.Please consult the sales representative for details.

3.1Ambientconditions

Atmospheric pressure:85kPa 106kPa Ambient temperature:See Clause 3.2 Relative humidity: 5 % ~ 9 5 % (non-condensing)

3.2Ambienttemperature

Generally,thesensorcanbeusedinthemedium temperature range shown in the table below.

Theworking environment of the converter shall meet the following requirements.

3.3Process temperature

Formass flow measurement, the influence of process temperature is defined as the change of sensor flow accuracy specification due to the deviation of process temperature from the calibration temperature.

For density measurement,the influence of process temperature is defined as the change of density accuracy specification due to the deviationof process temperature from the calibration temperature.

The zero-point calibration and intelligent instrument self-calibration toolscan beused to correct all influence of process temperature.

3.4Processpressure influence

The process pressure influence is defined as the change of mass flow and density accuracy of the sensor caused by the deviation of process pressure from the nominal pressure.The influence can be corrected by dynamic pressure input or fixed instrument coefficient. Consult the sales representative for details.
