6 Rotamass Prime Measuring principle and flow meter Measuring principle 2 Measuring principle and flow meter 2.1 Measuring principle The measuring principle is based on the generation of Coriolis forces. For this purpose, a driver system (E) excites the two measuring tubes (M1, M2) in their first resonance frequency. Both pipes vibrate inversely phased, similar to a resonating tuning fork. Q inlet S1 F1 -F1 outlet M1 -A -F2 M2 A Fig. 1: Coriolis principle E F2 S2 M1,M2 Measuring tubes E Driver system S1, S2 Pick-offs A Direction of measuring tube vibration F1, F2 Coriolis forces Q Direction of medium flow 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 or outflow side. These forces are directly proportional to the mass flow and result in deformation (torsion) of the measuring tubes F2 A E α A E 3 F1 1 Fig. 2: Coriolis forces and measuring tube deformation 1 Measuring tube mount A E Rotational axis 2 Medium F1, F2 Coriolis forces 3 Measuring tube α Torsion angle 6 / 68 GS 01U10B04-00EN-R_001, 1st edition,

7 Measuring principle Rotamass Prime Measuring principle and flow meter The small deformation overlying the fundamental vibration is recorded by means of pickoffs (S1, S2) attached at suitable measuring tube locations. The resulting phase shift Δφ between the output signals of pick-offs S1 and S2 is proportional to the mass flow. The output signals generated are further processed in a transmitter. y S2 S1 t Δφ Fig. 3: Phase shift between output signals of S1 and S2 pick-offs dm Δφ ~ F C ~ dt Density measurement Δφ m t dm/dt Phase shift Dynamic mass Time Mass flow Using a driver and an electronic regulator, the measuring tubes are operated in their resonance 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. Altering the density and the attendant mass will alter the resonance frequency. The transmitter measures the resonance frequency and calculates density from it according to the formula below. Device-dependent constants are determined individually during calibration.

This temperature approximately equals the medium temperature and is made available as a measured quantity at the transmitter as well. GS 01U10B04-00EN-R_001, 1st edition, 1st edition, / 68

14 Rotamass Prime Accuracy Overview 4 Accuracy In this chapter, maximum deviations are indicated as amounts. The actual values may deviate from the measured values by exceeding them or falling below. 4.1 Overview Achievable accuracies for liquids The value D flat specified for accuracy of mass flow applies for flow rates exceeding the mass flow limit Q flat. If the mass flow is less, it is necessary to also consider zero point stability Z, see Zero point stability of the mass flow [} 15]. The following values are achieved at calibration conditions when the device is delivered, see Calibration conditions [} 22].

Includes the combined effects of repeatability, linearity and hysteresis. In the event of medium temperature jumps, a delay is to be expected in the temperature being displayed due to low heat capacity and heat conductivity of gases.

15 Zero point stability of the mass flow Rotamass Prime Accuracy 4.2 Zero point stability of the mass flow The values D flat specified for accuracy of mass flow apply for flow rates exceeding the mass flow limit Q flat.

If gas pressure is a known value, after entering a reference density, the transmitter is able to calculate gas density from temperature and pressure as well (while assuming an ideal gas). Alternatively, there is an option for measuring gas density. In order to do so, it is necessary to adapt the lower density limit value in the transmitter. Additional information can be found in the related software instruction manual. For most applications the direct measurement of the gas density will have insufficient accuracy (see chapter Accuracy of mass flow and density according to [} 19]). 18 / 68 GS 01U10B04-00EN-R_001, 1st edition,

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 Fig. 11: Installation position to be avoided: Flow meter in sideways position Sensor installation position Sensor installation position as a function of the medium Installation position Medium Description Horizontal, measuring tubes at bottom Liquid The measuring tubes are oriented toward the bottom.

Avoid installation locations susceptible to cavitation, such as immediately behind a control valve. 4. Avoid installation directly behind rotary and gear pumps to prevent fluctuations in pressure from interfering with the resonance frequency of the Rotamass measuring tubes. 5.3 Process conditions Medium temperature range The Rotamass specification for use in Ex areas is different, see Ex instruction manual (IM 01U10X -00EN).
