The meter has no moving parts and any potential for fluid contamination is eliminated by the non-metallic corrosion-resistant body materials. Operating Conditions Application.

Basics Of Vortex Flow Meter With Pdf What Is Piping

The longest transmission distance between the signal converter and the sensor is 10 meters and the connecting cable is a 2-core shielded cable.

. Flow direction 13 Documentation For an overview of the scope of the associated Technical Documentation refer to the following. Tex shedding is proportional to the flow velocity v. VFM60 Vortex Flow Meter VFM60 is a powerful flow meter utilizing Karman vortex theory which can meet the requirement of measuring the flow rate of various fluids such as gas steam and liquid.

Rosemount Reducer Vortex Technology Low Flow Cut-Off 0 FLOW RANGE 100 Typical Application Range 101 Multivariable vortex flowmeters eliminate the need for a separate temperature measurement point and a flow computer. Liquid 12 62 to 200 - 2000 m3h GasSteam 5 25 to 1380 - 11000 m3h Ambient Temperature. Vortex Shedding Bluff Body Receiver Flow Housing Transmitter Ultrasonic Waves Karman Vortex.

This manual provides installation configuration operation troubleshooting and other procedures for the use of the Rosemount8800D Vortex Flow Meter. JOHNSON The conventional vortex shedding flowmeter performs satisfactorily in the metering of many types of fluid but the reliability of its sensor can be questionable when exposed to hostile environments. The signal processing part is separated from the watch body and can be applied to various harsh industrial sites.

The Rosemount 8600D Vortex Flowmeter consists of a meter body and transmitter and measures volumetric flow rate by detecting the vortices created by a fluid passing by the shedder bar. The outputs include 4-20 mA and pulse for flow rate as well as high and low alarms. Functional principle SITRANS FX330 Flange SITRANS.

The turndown is 10. VFM-250 series Vortex flow meters are designed for measuring the volumemass flow of liquids gases and steam based on Karman vortex principle. The shedding of these vortices due to the flow forms a vortex trail Karman street.

Unfortunately most designs embed the temperature sensor into the wetted vortex assembly. 1 and the accuracy is better than 5 of full scale. The nondimensional Strouhal number S describes the relation-shipbetween vortex frequency f width b of the bluff body and the mean flow velocity v.

Vortex flow measuring principle This measuring principle is based on the fact that turbulence forms downstream of obstacles in the flow such as a bridge pier. The multivariable vortex flow meter can measure flow rate and temperature simultaneously eliminating the need for separate components and associated installation costs. Configuration contains information on entering and verifying basic configuration parameters.

Adopting advanced differential algorithm along with measurement of isolation shielding and wave filtering VFM-250 series vortexflow metershav ethe adv antagesofimmunity on vibr ationand noise. The vortex ﬂ owmeter is a heavy instrument. Principle of measurement FV4000 1 Solid body 2 Piezo sensor.

As the fluid flows over and under the solid body vortices are shed alternately above and below. The meters come pre-calibrated for the specific range as determined by size. For model code ordering information see the Product Data Sheet.

Inside each vortex flowmeter a bluff body is therefore located in the middle of the pipe. Basics of Vortex Flow Meter With PDF Written by Anup Kumar Dey in Instrumentation Piping Design Basics Piping Interface The Vortex Flow Meter is one of the various types of volume flowmeters that are used frequently in the oil and gas industry to measure the flow inside a pipe. Vortex flowmeter BA01154D06EN0415 71299401 Valid as of version 0102zz Device firmware Proline Prowirl F 200 HART 2 EndressHauser.

Flowmeter operates on 108 to 42 Vdc terminal voltage with 250-ohm minimum load required for HART communications 168 Vdc power supply is required. The split type flow meter is used in a humid environment or a place with high temperature. Therefore the frequency of vortex shedding is proportional to the volume flow.

V b The vortex frequency is recorded at the sensor and evaluated at the converter. Vorticeswill only occur from a certain velocity Re-number on-wards consequently vortex meters will have. Gas Liquid Steam Meter size.

Usage even at low flow rates. Vol I July 1990 183 An electrostatic vortex shedding meter J. The Flowmeters case features a 4-digit local display to show the current flowrate measurement and red warning lights to visually indicate high and low flowrate alarms.

Pipe Diameters PD. The meter requires a nominal 24 VDC power source and outputs a visual display of flow as well as 4-20 mA proportional to flow and a field settable solid state relay for low flow alarm conditions. Downstream distances between the meter and a valve or a change-in-direction must also be followed.

The best accuracy is achieved with at least 20 PD upstream and 5 PD downstream for FV-200 vortex fl ow meters. When the vortex ﬂ owmeter is processing. Vortex meters are essentially frequency meters since they measure the frequency of vortices generated by a bluff body orshedder bar.

The product uses the VFM60 transmitter technology which provides with the excellent signal processing capability and enhance the vortex metering. The meter body is installed in-line with process piping. Vortex Flow Meter RVL Series VRX-DS-01586-EN-08 April 2019 Product Data Sheet DESCRIPTION The RVL liquid flow meter uses vortex-shedding technology with embedded piezoelectric pressure sensors.

This series of vortex flowmeter is designed on Comate Intellignet Sensor PA60 plateform Every parts utilized is universal for all RIF360 series products. For example 10 PD means place the fl ow meter ten times its inside diameter away from the source of turbulence. DN 15 to DN300 Flow.

Be careful that no damage is caused to personnel through accidentally dropping it or by exerting excessive force on the vortex ﬂ owmeter. The flow pass by is called coefficient of the instrument K KNV formula 3 RIF360 series digital vortex flowmeter is designed to provide most reliable performence. - 20 to 350 deg C.

F S. The operating principle of the Vortex flowmeter is based on the Karman street. When moving the vortex ﬂ owmeter always use a trolley and have at least two people carry it.

- 20 to 70 deg C.
