Function and system design Measuring principle The measuring principle is based on the controlled generation of Coriolis forces. These forces are always present in a system when both translational and rotational movements are superimposed. F c = 2 m (ν ω) F c = m = ω = ν = Coriolis force moving mass rotational velocity radial velocity in rotating or oscillating system The amplitude of the Coriolis force depends on the moving mass m, its velocity ν in the system and thus on the mass flow. Instead of a constant rotational velocity ω, the sensor uses oscillation. In the sensor, two parallel measuring tubes containing flowing fluid oscillate in antiphase, acting like a tuning fork. The Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations (see illustration): t zero flow (when the fluid is at a standstill) the two tubes oscillate in phase (1). Mass flow causes deceleration of the oscillation at the inlet of the tubes (2) and acceleration at the outlet (3) The phase difference (-) increases with increasing mass flow. Electrodynamic sensors register the tube oscillations at the inlet and outlet. System balance is ensured by the antiphase oscillation of the two measuring tubes. The measuring principle operates independently of temperature, pressure, viscosity, conductivity and flow profile. Density measurement The measuring tube is continuously excited at its resonance frequency. change in the mass and thus the density of the oscillating system (comprising measuring tube and fluid) results in a corresponding, automatic adjustment in the oscillation frequency. Resonance frequency is thus a function of medium density. The microprocessor utilizes this relationship to obtain a density signal. Volume measurement Together with the measured mass flow, this is used to calculate the volume flow. 4 Endress+Hauser

5 Temperature measurement The temperature of the measuring tube is determined in order to calculate the compensation factor due to temperature effects. This signal corresponds to the process temperature and is also available as an output signal. Measuring system The device consists of a transmitter and a sensor. One device version is available: compact version, transmitter and sensor form a mechanical unit. Transmitter Promass Device versions and materials: Compact, aluminum coated: Coated aluminum lsi1mg Compact, hygienic, stainless: Hygienic version, for maximum corrosion resistance: stainless steel (316) Configuration: External operation via four-line, illuminated local display with touch control and guided menus ("Make-it-run" wizards) for applications Via operating tools (e.g. FieldCare) Sensor Promass E Multipurpose sensor Ideal substitute for volumetric flowmeters Nominal diameter range: 8 to 5 (³ ₈ to 2") Materials: Sensor: stainless steel (34) Measuring tubes: stainless steel (94) Process connections: stainless steel (316/316) Input Measured variable Direct measured variables Mass flow Density Temperature Calculated measured variables Volume flow Corrected volume flow Reference density Measuring range Measuring ranges for liquids Measuring range full scale values min(f) to max(f) [kg/h] [lb/min] 8 ³ ₈ to 2 to ½ to 65 to to 18 to ½ to 45 to to 7 to 2 57 Endress+Hauser 5

6 Measuring ranges for gases The full scale values depend on the density of the gas and can be calculated with the formula below: max(g) = max(f) ρ G : x max(g) max(f) Maximum full scale value for gas [kg/h] Maximum full scale value for liquid [kg/h] max(g) < max(f) ρ G max(g) can never be greater than max(f) Gas density in [kg/m³] at operating conditions x [kg/m 3 ] 8 ³ ₈ ½ ½ Operable flow range Over 1 : 1. To calculate the measuring range, use the pplicator sizing tool ( 59) Calculation example for gas Sensor: Promass E, 5 Gas: ir with a density of 6.3 kg/m³ (at 2 C and 5 bar) Measuring range (liquid):7 kg/h x = 125 kg/m³ (for Promass E, 5) Maximum possible full scale value: max(g) = max(f) ρ G : x = 7 kg/h 6.3 kg/m³ : 125 kg/m³ = 33 8 kg/h Recommended measuring range "Flow limit" section ( 35) Flow rates above the preset full scale value are not overridden by the electronics unit, with the result that the totalizer values are registered correctly. Input signal External measured values To increase the accuracy of certain measured variables or to calculate the corrected volume flow for gases, the automation system can continuously write the operating pressure to the measuring device. Endress+Hauser recommends the use of a pressure transmitter for absolute pressure, e.g. Cerabar M or Cerabar S. Various pressure transmitters and temperature measuring devices can be ordered from Endress +Hauser: see "ccessories" section ( 6) It is recommended to read in external measured values to calculate the following measured variables: Mass flow Corrected volume flow HRT protocol The measured values are written from the automation system to the measuring device via the HRT protocol.

Mounting location To prevent measuring errors arising from accumulation of gas bubbles in the measuring tube, avoid the following mounting locations in the pipe: Highest point of a pipeline. Directly upstream of a free pipe outlet in a down pipe Installation in down pipes However, the following installation suggestion allows for installation in an open vertical pipeline. Pipe restrictions or the use of an orifice with a smaller cross-section than the nominal diameter prevent the sensor running empty while measurement is in progress. Endress+Hauser 23

Orientation Recommendation Vertical orientation Horizontal orientation, transmitter head up 1) Exception: ( 1, 25) C Horizontal orientation, transmitter head down 2) Exception: ( 1, 25) D Horizontal orientation, transmitter head at side ) pplications with low process temperatures may reduce the ambient temperature. To maintain the minimum ambient temperature for the transmitter, this orientation is recommended. 2) pplications with high process temperatures may increase the ambient temperature.

35 Rupture disk Flow limit To increase the level of safety, a device version with a rupture disk with a triggering pressure of 1 to 15 bar (145 to psi) can be used. Special mounting instructions: ( 25) Rupture disks cannot be combined with the separately available heating jacket ( 57) ( 57). Select the nominal diameter by optimizing between the required flow range and permissible pressure loss. For an overview of the measuring range full scale values, see the "Measuring range" section ( 5) The minimum recommended full scale value is approx. 1/2 of the maximum full scale value In most applications, 2 to 5 % of the maximum full scale value can be considered ideal Select a lower full scale value for abrasive substances (such as liquids with entrained solids): flow velocity <1 m/s (<3 ft/s). For gas measurement the following rules apply: The flow velocity in the measuring tubes should not exceed half the sonic velocity (.5 Mach). The maximum mass flow depends on the density of the gas: formula ( 6) Pressure loss To calculate the pressure loss, use the pplicator sizing tool ( 59) System pressure It is important that cavitation does not occur, or that gases entrained in the liquids do not outgas. This is prevented by means of a sufficiently high system pressure. For this reason, the following mounting locations are recommended: t the lowest point in a vertical pipe Downstream from pumps (no danger of vacuum) Thermal insulation Heating In the case of some fluids, it is important that the heat radiated from the sensor to the transmitter is kept to a minimum. wide range of materials can be used for the required insulation. Ensure that only up to 2 mm (.79 in) of the transmitter neck is insulated so that the transmitter head is completely free. Some fluids require suitable measures to avoid loss of heat at the sensor. Heating options Electrical heating, e.g. with electric band heaters Via pipes carrying hot water or steam Via heating jackets Heating jackets for the sensor can be ordered as accessories from Endress+Hauser ( 57). Vibrations The high oscillation frequency of the measuring tubes ensures that the correct operation of the measuring system is not influenced by plant vibrations. Endress+Hauser 35
