Mass flow The medium flow through the vibrating measuring tubes generates Coriolis forces (F1, -F1 and F2, -F2) that produce positive or negative values for the tubes on the inflow oroutflow side. These forces are directly proportional to the mass flow and result in defor-mation (torsion) of the measuring tubes.

The small deformation overlying the fundamental vibration is recorded by means of pick-offs (S1, S2) attached at suitable measuring tube locations. The resulting phase shift Δφbetween the output signals of pick-offs S1 and S2 is proportional to the mass flow. Theoutput signals generated are further processed in a transmitter.

Densitymeasurement
Using a driver and an electronic regulator, the measuring tubes are operated in their res-onance frequency ƒ. This resonance frequency is a function of measuring tube geometry,material properties and the mass of the medium covibrating in the measuring tubes. Alter-ing the density and the attendant mass will alter the resonance frequency. The transmittermeasures the resonance frequency and calculates density from it according to the for-mula below. Device-dependent constants are determined individually during calibration.

Temperaturemeasurement
The measuring tube temperature is measured in order to compensate for the effects oftemperature on the flow meter. This temperature approximately equals the medium tem-perature and is made available as a measured quantity at the transmitter as well.

Rotamass NanoApplication and measuring ranges Measured quantity
The Rotamass Coriolis flow meter can be used to measure the following media: Liquids Gases Mixtures, such as emulsions, suspensions, slurries
Possible limitations applying to measurement of mixtures must be checked with the re-sponsible Yokogawa sales organization.
The following variables can be measured using the Rotamass: Mass flow Density Temperature
Based on these measured quantities, the transmitter also calculates: Volume flow Partial component concentration of a two-component mixture Partial component flow rate of a mixture consisting of two components (net flow)
In this process, the net flow is calculated based on the known partial componentconcentration and the overall flow.
Mass flow of gases When using the Rotamass for measuring the flow of gases, the mass flow is usually lim-ited by the pressure loss generated and the maximum flow velocity. Since these dependheavily on the application, it is strongly recommended that the Yokogawa FlowConfigura-tor software be used or the responsible Yokogawa sales organization be contacted whendesigning the size of the device.
When using the Rotamass for measuring the flow of gases, the flow rate is usually limitedby the pressure loss generated and the maximum flow velocity. Since these dependheavily on the application, it is strongly recommended that the Yokogawa FlowConfigura-tor software be used or the responsible Yokogawa sales organization be contacted whendesigning the size of the device.
3.5 Pressure loss
The pressure loss along the flow meter is heavily dependent on the application. The pres-sure loss of 1 bar at nominal mass flow Qnom also applies to water and is considered thereference value. Use of the Yokogawa FlowConfigurator software is recommended forachieving an accurate design.
Rotamass NanoApplication and measuring ranges Density
In this chapter, maximum deviations are indicated as amounts. The actual values maydeviate from the measured values by exceeding them or falling below.
4.1 Overview
Achievableaccuracies forliquids
The value Dflat specified for accuracy of mass flow applies for flow rates exceeding themass flow limit Qflat. If the mass flow is less, it is necessary to also consider zero point sta-bility Z, see Zero point stability of the mass flow [ 14].
The following values are achieved at calibration conditions when the device is delivered,see Calibration conditions [ 21]. For small meter sizes, specifications may not be as ac-curate, see Mass flow and density accuracy [ 57].

In the event of medium temperature jumps, a delay is to be expected in the temperaturebeing displayed due to low heat capacity and heat conductivity of gases.
The connecting cable impacts the accuracy. The values specified are valid for connectingcables < 30 m long.
The values Dflat specified for accuracy of mass flow apply for flow rates exceeding themass flow limit Qflat. If the mass flow is less, it is necessary to also consider zero point sta-bility Z (see chapter Mass flow accuracy [ 14]).
Above mass flow Qflat, maximum deviation is constant and referred to as Dflat. It dependson the product version selected and can be found in the tables in chapter Accuracy ofmass flow and density according to MS code [ 18].
Taking zero point stability into consideration, the following calculation formulas are to beused for maximum deviation D:

4.3.2 Sample calculation for gasesThe maximum deviation in the case of gases depends on the product version selected,see also Mass flow and density accuracy [ 57].
Example: Medium: GasZero point stability Z: 0.048 kg/hFactor k 2Maximum deviation Dflat: 0.5 %Value of mass flow Q: 10 kg/h
Since the mass flow of gas measurements is low, use of the Yokogawa FlowConfiguratorsoftware is recommended for designing the suitable product and contacting the responsi-ble Yokogawa sales office for this purpose.

The maximum deviation depends on the product version selected, see also Accuracy ofmass flow and density according to MS code [ 18].
4.4.2 For gasesIn most applications, density at standard conditions is entered into the flow meter andused to calculate the standard volume flow based on mass flow.
If gas pressure is a known value, after entering a reference density, the transmitter is ableto calculate gas density from temperature and pressure as well (while assuming an idealgas).
Alternatively, there is an option for measuring gas density. In order to do so, it is neces-sary to adapt the lower density limit value in the transmitter. Additional information can befound in the related software instruction manual.
For most applications the direct measurement of the gas density will have insufficient ac-curacy (see chapter Accuracy of mass flow and density according to MS code [ 18]).

4.5 Accuracy of mass flow and density according to MS code
Accuracy for flow rate as well as density is selected via MS code position 9. Here a dis-tinction is made between devices for measuring liquids and devices for measuring gases.No accuracy for density measurement is specified for gas measurement devices.
4.6.1 For liquidsThe following formula can be used to calculate the accuracy of liquid volume flow:

4.6.2 For gasesAccuracy of standard volume flow for gas with a fixed composition equals the maximumdeviation D of the mass flow.
DV = D
In order to determine the standard volume flow for gas, it is necessary to input areference density in the transmitter. Additional information can be found in the re-lated software instruction manual. The accuracy specified is achieved only forfixed gas composites. Major deviations may appear if the gas compositionchanges.
When using default damping times, the specified repeatability of mass flow, density andtemperature measurements equals half of the respective maximum deviation.

4.9 Calibration conditions
4.9.1 Mass flow calibration and density adjustmentAll Rotamass are calibrated in accordance with the state of the art at Rota Yokogawa.Optionally, the calibration can be performed according to a method accredited by DAkkSin accordance with DIN EN ISO/IEC 17025:2005 (Option K5, see Certificates [ 64]).
Each Rotamass device comes with a standard calibration certificate.
Calibration takes place at reference conditions. Specific values are listed in the standardcalibration certificate.
Medium temperature10...35 °CAverage temperature: 22.5 °C
Ambient temperature 10...35 °CProcess pressure (absolute) 1...2 bar
The accuracy specified is achieved at as-delivered calibration conditions stated.
4.9.2 Density calibrationDensity calibration is performed for maximum deviation of 0.5 g/l (MS code position 9 2).
Density calibration includes: Determination of calibration constants for medium densities at 0.7 kg/l, 1 kg/l and 1.65
kg/l at 20 °C medium temperature Determination of temperature compensation coefficients at 20...80 °C Check of results for medium densities at 0.7 kg/l, 1 kg/l and 1.65 kg/l at 20 °C medium
temperature Special configuration of the temperature sensor: Creation of density calibration certificate
Rotamass Coriolis flow meters can be mounted horizontally, vertically and at an incline.The measuring tubes should be completely filled with the medium during this process asaccumulations of air or formation of gas bubbles in the measuring tube may result in er-rors in measurement. Straight pipe runs at inlet or outlet are usually not required.
Avoid the following installation locations and positions: Measuring tubes as highest point in piping when measuring liquids Measuring tubes as lowest point in piping when measuring gases Immediately in front of a free pipe outlet in a downpipe Lateral positions

Vertical, direction of flow towardsthe top
Liquid/gas
The sensor is installed on a pipe withthe direction of flow towards the top.Accumulation of gas bubbles or solidsis avoided. This position allows forcomplete self-draining of the measuringtubes.
The following instructions for installation must be observed:1. Protect the flow meter from direct sun irradiation in order to avoid exceeding the maxi-
mum allowed internal temperature of the transmitter.2. In case of installing two sensors of the same kind back-to-back redundantly, use a
customized design and contact the responsible Yokogawa sales organization.3. Avoid installation locations susceptible to cavitation, such as immediately behind a
control valve.4. In case that the medium temperatures deviate approx. 80 °C from the ambient tem-
perature, insulating the sensor is recommended if the goal is to maintain utmost accu-racy, see Insulation and heat tracing [ 28].
5. Avoid installation directly behind rotary and gear pumps to prevent fluctuations inpressure from interfering with the resonance frequency of the Rotamass measuringtubes.

Electrical heating can be provided subsequently, such as in the form of heating tapes, aheating jacket or by way of hot water or steam running through copper pipes. When usingheat tracing, the sensor must be magnetically shielded in case its heat control is realizedby way of phase-angle control or pulse packets.
In hazardous areas, subsequent application of insulation, heating jacket or heat-ing strips is not permitted.

– Power frequency: 47...63 Hz Direct-current voltage:
– Power supply: 24 VDC or 100...120 VDC
Power consumption P = 10 W (including sensor)Power supply failure In the event of a power failure, the flow meter data are backed up on a non-volatile inter-
nal memory. In case of devices with display, the characteristic sensor values, such asnominal diameter, serial number, calibration constants, zero point, etc. and the error his-tory are also stored on a microSD card.
Critical values may also be recorded on a microSD card during operation. It also holdsproduct documentation and a data backup of factory settings in order to facilitate recoveryin case of device failure.
In the event of a power failure, the flow meter bridges at least one power line cycle.Potentialequalization
Potential equalization must be ensured at all times, see user's manualIM 01U10A-00EN With respect to explosion protection, refer to the relevant informationin the specific documents in the Ex instruction manual IM 01U10X0-00EN.

9.2.4 Concentration measurementThe standard concentration measurement (device option CST) can be used for concen-tration measurements of emulsions or suspensions when density of the media involveddepends only on temperature.
The standard concentration measurement can also be used for many low-concentrationsolutions if there is only minor interaction between the liquids or if the miscibility is negligi-ble. For questions regarding a specific application, contact the responsible Yokogawasales organization. The appropriate density coefficients must be determined prior to usingthis option and input into the transmitter. To do so, the recommendation is to determinethe necessary parameters from density data using DTM in the Yokogawa FieldMate pro-gram or the calculation tool inclduded in the delivery.
The advanced concentration measurement is recommended for more complex applica-tions, such as for liquids that interact.
