2 VersaFlow Vortex 100 Vortex Flow Meter 2 Options and Variants 1. The universal device with temperature compensation for saturated steam integrated as standard The VERSAFLOW as a compact flowmeter in a flange version is suitable for universal use in measuring liquids, gases and vapors. The temperature compensation for saturated steam is integrated as standard, thus enabling direct compensation of the density; the mass and energy can also be measured. Here ISP (Intelligent Signal Processing) provides stable measurement results free of external perturbations. 2. The easy to install sandwich version with optimised centering rings The VERSAFLOW as a compact flowmeter in a sandwich version is suitable for universal use in the measurement of liquids, gases and vapors. The temperature compensation for saturated steam is integrated as standard. The flowmeter is provided with additional optimised centering rings. The VERSAFLOW can be aligned centrically by turning the centering rings, eliminating any offset between the VERSAFLOW and the pipeline.

3 VersaFlow Vortex 100 Vortex Flow Meter 3 3. The only 2-wire device with integrated pressure and temperature compensation The VERSAFLOW as a flange or sandwich flowmeter is optionally available with integrated pressure and temperature compensation for gases, wet gases, gas mixtures or vapors. The advantages of this unique design couldn't be clearer: No additional cost-intensive installation of pressure and temperature sensors No additional cabling work No faulty measurement results, because pressure, temperature and volume flow can be read at a single point Direct measurement of mass and/or energy 4. The highest process availability thanks to optional shut-off valve As an option, HONEYWELL can supply the VERSAFLOW with a shut-off valve to allow the pressure sensor to be exchanged without interrupting the process. What is more, the pressure sensor can be shut off for the purpose of pressure or leak testing of the pipeline. Using the built-in two-way valve, the pressure sensor can also be calibrated and tested at a later time.

4 VersaFlow Vortex 100 Vortex Flow Meter 4 5. Dual measurement for twofold reliability The VERSAFLOW is optionally available as a dual version. This is a genuine redundant system with two independent sensors and two converters. This provides twofold functional reliability and availability of the measurement. This variant is optimally suited for measurements in multiproduct pipelines. In such pipelines, two different products are moved through one after the other. Here one converter can be programmed for one product, and the other converter for the other product. 6. Remote electronics option allows easier access to the local programming and display Both the sandwich and the flanged versions of the VersaFlow Vortex neter are available with compact or remote electronics. The option of remote electronics does not limit the choice of integral pressure sensing or the ability to select the dual measurement option. The remote converter can be mounted up to 30m from the sensor.

5 VersaFlow Vortex 100 Vortex Flow Meter 5 PACTware Simple and Intuitive PACTware diagnosis The VERSAFLOW is PACTware-ready. Each device is supplied ex factory with the appropriate DTM (Device Type Manager). A DTM is a device driver containing a user interface optimised for each device, and which makes the device functionality available independently of the field bus protocol. A graphical user interface enables operation and configuration of the meter. Simple, program-based setup of devices is thus possible from the control room, even without a display or keyboard. The best possible operator control concepts have been implemented, optimised for the user's requirements. PACTware reading display Features: Displays measured values Records measured information during operation Shows status of device Stepwise setup Displays summary of setup selection for final checking PACTware online parameter configuration

18 VersaFlow Vortex Meters Using internal pressure and temperature compensation for improved performance and reduced energy cost The VersaFlow Vortex meter is the only meter of its type on the market that offers integral temperature compensation standard and the option of integral pressure compensation. These features offer improved system accuracy and can significantly reduce energy costs. Virtually all industries rely on steam to generate power, heat facilities or clean process lines. Steam efficiency is measured in two basic areas--how effective is the steam production (boiler efficiency) and how effective is the transport of steam throughout the facility (leakage detection and heat loss). The ability to measure pressure and temperature and calculate heat allows the VersaFlow Vortex meter to monitor the production and transfer of steam. The below diagram illustrates the traditional use of an uncompensated Vortex meter with a separate pressure sensor, temperature sensor and flow computer. Along with increased potential leak points, you have the total installed cost and accuracy issues to contend with. Typical installed cost of a 2 Vortex meter in a system is shown: Vortex Meter $2500 plus 1.5 hour 150/hr Temperature Sensor $350 plus 1 hour labor Pressure Sensor $650 plus 1 hour labor Flow Computer to calculate steam flow $1350 plus 1.5 hour labor Total Installed Cost: $5600 VersaFlow Vortex with Integral Temperature, Pressure and Steam Calculation: $4800 plus 1.5 hour labor. Total Installed Cost: $5025 Cost Savings: $575 System accuracy improved from ± 3% to ± 1% Flow Computer Power Supply 55.6 Potential Leak Point Flow 4-20 ma Pulse Output Vortex instrument Pressure Temperature System accuracy at best ± 3%

19 VersaFlow Vortex 2 Saturated Steam In most saturated steam applications the operating temperature and pressure is a known quantity coming off the boiler. Depending on the insulation, as well as leakage in the pipeline, not to mention boiler efficiency, temperature and pressure will not always remain at the ideal levels expected. Saturated steam has a fixed pressure to temperature relationship. Integral temperature measurement is all that is required. Assuming a constant temperature can lead to errors as shown in the example. 3 meter 5911 Kg/hr Saturated steam with a presumed 350 F temperature Deg F 350 Psia 134 Kg/hr 5911 Error Superheated Steam In superheated steam the pressure and temperature are independent. It is recommended that both are tracked. As shown in the example, as temperature changes, even if pressure remains constant the errors can rapidly increase. 3 meter kg/hr Superheated Steam at 350 deg F and 20 psig Temperature Flow Output Error % % % % % % % % % % % % -30.4% -38.5% -46.9% 11.8% 22.4% 32.0% 40.6% Pressure Flow Output Error % % % % % % % % % % % A +50 def F change creates a -47% error A -50 deg F change creates a + 48% error An integral temperature sensor and integral steam tables in the VersaFlow Vortex meter maintains the 1% accuracy A 20 deg F change leads to a 2.5% error A 50 deg F change leads to a 6% error A 100 deg F change leads to a 11.5% error VersaFlow Vortex with integral temperature sensor and integral superheated steam tables maintains the 1% accuracy. Likewise if pressure shifts even by a couple of psi, the errors start to compound. A 10% change in pressure creates a 6% meter error A 50% change in pressure creates a 30% error in reading VersaFlow Vortex with integral pressure sensor and integral superheated steam tables maintains the 1% accuracy

20 monitor gas feed to the boiler. The other is in monitoring the Lbs Steam Lost per Total Cost per Total Cost VersaFlow efficiency of Vortex the steam lines transporting the steam. The major Size of Leak Month Month per Year 3 concern, once the line is designed, is the integrity of the 1/8 Inch 52,500 $ $3, pipeline and how much steam is being lost to leakage. 3/16 Inch 117,000 $ $7, ¼ Inch 210,000 $1, $12, VersaFlow Vortex is ideal for this task. By placing a vortex 5/16 Inch 325,000 $1, $19, meter at the discharge of the boiler and taking advantage of 3/8 Inch 470,000 $2, $28, the integral temperature measurement, you can easily 7/16 Inch 637,000 $3, $38, measure the steam being generated. If you have a flow meter ½ Inch 835,000 $4, $50, on the gas feed line, you can actually monitor boiler efficiency by comparing gas used to the pounds of steam produced (the vortex meter can easily measure in mass flow units because of NOTE: One pound of 100 psi steam contains about 1,200 the temperature compensation). Then by placing another BTUs. vortex meter at a designated spot further downstream of the If the steam is produced at 85% efficiency, the input energy is boiler you can make the measurement again and compare the 1,200 / 85% = 1,411 BTUs per pound. Therefore, 1,000 flow rate of the steam to what is coming off the boiler. Any pounds of steam requires at least 1.4 million BTUs to produce reduction in flow not accounted for by any usage points in it. (1,411 BTUs per pound x 1,000) between is attributable to leakage. 1 MCF of Natural Gas contains 1 million BTUs Cost to produce 1,000 lbs of steam from natural gas = 1.4 x $ As you can see in the table, even a small leak can cost per MCF of Natural Gas thousands of dollars a year, not to mention the additional cost When natural gas costs $7.00 per MCF, 1,000 lbs of steam to manufacture more steam to compensate. A ½ hole can cost costs (1.4 x $7) = $9.80 upwards of $50,000 in a year if left unchecked. (Source: Armstrong International) Another feature that the VersaFlow Vortex meter can provide is the ability to monitor heat loss. By use of the local display or the HART protocol you can track the temperature and see if there is any extraordinary heat loss from where you measured at the boiler. Heat loss means energy costs, so tracking this can be critical as well.
