Vortex Flow Meter Range 84F; 84W; 84S

vortex

The Foxboro vortex flowmeters are the highest-performing flowmeters on the market. These instruments are designed to be flexible and reliable in harsh process environments. Model 84 is available in sizes ¾" to 12" flanged; ¾" to 8" wafer; and 2" and 3" sanitary.
No other vortex flowmeter measures up for accuracy in liquid, gas and steam for temperatures up to 800ºF (430ºC).
Patented flexibility tuning improves accuracy under every operating condition. Additional benefits include real-time Reynolds number correction; correction for piping effects; adaptive filtering for noise rejection at varying flow rates; automatic low-flow cut in; tunable for specific operating conditions; and K-factory-corrected for temperature. They also have DirectSense™ technology: Performance and reliability backed with a lifetime sensor warranty.

Key Benefits

  • Unique vortex sensing with a lifetime warranty, including the option for a removable sensor without shutting down the process
  • Patented algorithms to improve performance in real-world applications
  • Broad offering in terms of sizes, materials and end connections, including models that are 3A approved for sanitary applications
  • Widest flow range available today
  • Ease of configuration using FDT technology

Wide variety of applications

Models 84F and 84W set the example for industry  standards whether the application requires accuracy  for totalizing and batching; utility metering of fluids in  the process industries; fuel, air, steam, or gas  metering for the measurement of energy in any high  use application; or stability and repeatability for process control.

“CE” compliance

These flowmeters comply with applicable European Community Standards for immunity to EMI emissions, and pressure equipment directive (PED) 97/23/EC.

Designed for best performance and reliability

This patented family of vortex flowmeters has the high accuracy and rangeability of positive displacement and turbine flowmeters without the mechanical complexity and high cost. They provide flow rate accuracy of ±0.5% in liquids and ±1.0% in gas and steam. It utilizes patented DirectSense technology to eliminate routine problems encountered with other vortex meters. DirectSense technology measures pressure pulses from vortex shedding directly, without losses due to mechanical linkages. The benefits of DirectSense technology include:
Provides best performance in class.
Increased measurement sensitivity for wider rangeability.
Greater immunity to pipe vibration.
High reliability backed by lifetime sensor warranty.
Replaceable sensor without recalibrating.
Because these vortex flowmeters have no moving parts, they are very durable and reliable. The simplicity of design ensures low initial cost, low operating and maintenance costs, which contribute to an overall lower cost of ownership.

Simplified Start-up

No primary device calculations or mechanical calibrations are required. The flowmeter is easily installed and configured. Simply wire it to a proper power source, an I/O module, or controller, and it is ready to measure flow. Invensys will preconfigure the flowmeter using flow data supplied by the customer. Generically preconfigured flowmeters can be used as shipped, but for more precise application, the flowmeter should be configured to specific process usage. The configurator allows selection of the fluid type, and provides general default configurations when process conditions are not available.

Activetuning Algorithm

Reynolds Number
Patented algorithm improves accuracy performance down to an RD of 5000.
Compensations for Piping Effects
When it is not possible to provide the recommended pipe diameters of unobstructed straight pipe upstream of the flowmeter, the 84 Series can be configured to compensate for most of the common non ideal upstream conditions, such as elbows and reducers. Straight runs as short as 5-pipe diameters can be configured to achieve full accuracy.
Adaptive Filtering and Signal Conditioning
A patented, adaptive filtering algorithm provides real time, dynamic frequency filters that follow the vortex shedding frequency. This results in unsurpassed low- flow measurement capability and vibration immunity. This is incorporated with a digital smoothing algorithm that conditions the raw vortex signal to virtually eliminate dropped or added pulses, further enhancing low-flow performance.
Tunable for Specific Operating Conditions
Configurable parameters for Low Flow Cut-in and damping allow tuning for specific flow conditions.

Compact, efficient and durable design

The flowmeter mounts between ANSI or EN 1092-1 raised face flanges. See Model Code section for end connections offered with each line size. Other flange face surfaces can be used as a custom design.
The electronics housing is of explosionproof and flameproof construction and provides environmental protection to the enclosed electronics. It is offered integrally mounted to the flowtube, or can be mounted remotely.
The flowmeter’s simple, modular design requires minimum maintenance. Common, field replaceable parts are used, including the sensor assembly and amplifier. The amplifier can be replaced without interrupting the flow in the pipe, and sensor can be replaced without process shutdown when an isolation valve is installed. Since a single device is used for multiprocess-fluid applications, ordering is simplified and spare part needs minimized.

Usable in hazardous area locations

These flowmeters meet numerous agency requirements for hazardous locations.

Measurement integration

These flowmeters provide efficient integration of measurements into HART process control schemes. They operate by using a bidirectional digital signal superimposed on the 4 to 20 mA current signal. They are also offered with or without a pulse output. Remote communication of digital values plus status and configuration information can be achieved via HART communication protocol.
Configurators used with the HART versions are:
The HART Communicator (users having a HART Communicator for other devices can have them upgraded with Invensys software to accommodate these flowmeters).
The Local Digital Indicator/Configurator with pushbuttons.
A PC-based configurator.
With HART, digital multidropping is permitted. This is the connection of several transmitters to a single communications line. Up to fifteen transmitters can be connected on a single twisted pair of wires or over leased telephone lines.

Remote mounted electronics housing

Remote mounting is offered to allow access to the amplifier and other housing electronics when the measurement is not in an easily accessible location. The remote housing is supported by a bracket, which in turn mounts to a surface or to a nominal 2-in or DN 50 pipe. This housing can be located up to a cable length of 50 ft (15.2 m) from the flowtube without loss of low level signal.

Local digital indicator/configurator

This is a full feature, 16-character digital indicator and configurator. Total flow and/or the instantaneous flow rate may be displayed in user-selected flow units. The display may be configured for either flow or total, or to toggle between them. Four pushbuttons on the indicator are used to configure the flowmeter.

Isolation valve

An isolation valve allows the sensor to be removed or replaced without interrupting the flow in the pipe.

Dual measurement flowmeter (84F only)

Dual measurement flowmeters provide the user with redundant sensors and electronics. Two electronics housings and sensors are mounted to a common flowmeter body assembly. Should one transmitter fail, the redundant measurement avoids the necessity of shutting down the process. The failed transmitter can then be replaced at some later noncritical time. Applications include Safety Shutdown Systems (independent of Process Measurement Network), Safety Backup for critical flow loops, Comparative Verification of Measurement for high accuracy precision loops, or just for dual communications paths with the same primary element.
