1 General Specifications GS 1E22-1E XF14 Magnetic Flowmeter onverter for Remote Flowtube The XF14 magnetic flowmeter converter is a sophisticated product with outstanding reliability and ease of operation, developed on the basis of decades of fieldproven experience. The XF14 employs an LD indicator, infra-red ray switches, and Easy Setup parameters to ensure ease of maintenance. The combination of a replaceable electrode type flowtube and diagnostics to detect the adhesion level on the electrodes dramatically improves maintainability. The XF14 also employs the fluid noise free Dual Frequency Excitation Method and the newly added Enhanced Dual Frequency Excitation Method as an option for more severe applications to ensure higher stability and quicker response. Note: The Dual Frequency Excitation Method is Yokogawa s unique technology. FETURES User Friendly Fluid dhesion Level Diagnosis y constantly monitoring the level of insulating substance on the electrodes, it is possible to determine when maintenance is required. With the utilization of a replaceable electrode type flowtube, in cases of severe adhesion, the electrodes can be easily removed from the meter and cleaned. lear and Versatile Indications The LD indicator employs a large, backlit full dot-matrix, that can facilitate various displays. One to three lines of indications are possible. When there is an alarm condition, a full description of the countermeasure is indicated. Easy Setup Parameters The most frequently used parameters are arranged in a group at the top. The infra-red ray switches enable the users to set parameters without opening the cover. Enhanced Performance and Specifications Enhanced Dual Frequency Excitation Method The Enhanced Dual Frequency Excitation Method can be optionally selected. For severe applications such as for high concentration slurry or low conductivity fluid, extremely stable measurements can be realized. Improved Minimum onductivity The lower limit of conductivity is from 1 S/cm. High-Speed Pulse : The pulse rate now goes up to 1, pps (pulse/ second) for use with high speed applications such as in short time batch processes. Versatile Input/ouput Function Now vailable Expansion of Product Lineup Two Types of ccuracy Standard accuracy is.35% of Rate, and High grade accuracy type (.2% of Rate) is also available.

3 Functions How to Set Parameters (*2): The indicator s LD and three infra-red ray switches enable users to set parameters without opening the case cover. Parameters can also be set by means of the HHT. Displayed Languages (*2): Users can choose a language from among English or Japanese. German, French, Italian, Spanish are now preparing. Instantaneous Flow Rate/Totalized Value Display Functions (for models with an indicator) (*2): The full dot-matrix LD enables arbitrary selections of displays from one line to three lines for: Instantaneous flow rate Instantaneous flow rate (%) Instantaneous flow rate (bar graph) urrent output value (m) Totalized value Tag No. Results of electrode adhesion diagnostics Totalizer Display Function (*2): The flow rate is counted one notch at a time according to the setting of totalization pulse weights. For forward/ reverse ranges, the totalized values of the flow direction (forward or reverse) and the flow rate are displayed on the indicator together with the units. The difference values between the forward and reverse flow rate totalized values can be displayed. The reverse flow rate is not counted for a forward single range. Damping Time onstant (*2): Time constant can be set from.1 second to 2. seconds (63% response). Span Setting Function (*2): Span flows can be arbitrarily set in units such as volume flow rate, mass flow rate, time, or flow rate value. The velocity unit can also be set. Volume Flow Rate Unit: kcf, cf, mcf, Mgal (US), kgal (US), gal (US), mgal (US), kbbl (US)*, bbl (US)*, mbbl (US)*, µbbl (US)*, Ml (megaliter), m 3, kl (kiloliter), l (liter), cm 3 Mass Flow Rate Unit (Density must be set.): klb (US), lb (US), t (ton), kg, g Velocity Unit: ft, m (meter) Time Unit: s (sec), min, h (hour), d (day) * US Oil or US eer can be selected Pulse (*1): Scaled pulse can be output by setting a pulse weight. Pulse Width:Duty 5% or fixed pulse width (.5,.1,.5, 1, 2, 33, 5, 1 ms) can be selected arbitrarily. Rate:.1 to 1, pps (pulse/second) Multi-range Function (*1)(*2): Status input enables the switching of up to two ranges. For automatic range switching, the status of up to four ranges can be shown in status outputs and on the indicator. 3 Forward and Reverse Flow Measurement Functions (*1)(*2): Flows in both forward and reverse directions can be measured. The status is shown in status outputs and on the indicator during the reverse flow measurement. Totalization Switch (*1): The status is output if a totalized value becomes equal to or greater than the set value. Preset Totalization (*1): The parameter setting or status input enables a totalized value to be preset to a setting value or zero. % Signal Lock (*1)(*2): Status input forcibly fixes the instantaneous flow rate display, current output, pulse output, and flow rate totalization to %. larm Selection Function (*2): larms are classified into System larms (hard failures), Process larms (such as Empty Pipe, Signal Overflow and dhesion larm ), Setting larms, and Warnings. Whether alarms should be generated or not can be selected for each item. The current output generated for an alarm can be selected arbitrarily from among 2.4 m or less, fixed to 4 m, 21.6 m or more, or HOLD. larm (*1): larms are generated only for the items selected via the larm Selection Function if relevant failures occur. Self Diagnostics Functions (*2): If alarms are generated, details of the System larms, Process larms, Setting larms and Warnings are displayed together with concrete descriptions of countermeasures. Flow Upper/Lower Limit larms (*1): If a flow rate becomes greater or smaller than the set value, this alarm is generated. In addition, two upper limits (H, HH) and two lower limits (L, LL) can be set. If a flow rate becomes greater or smaller than any of the set values, the status is output. Electrode dhesion Diagnostics Function (*1) (*2): This function enables monitoring of the adhesion level of insulating substances to the electrodes. Depending on the status of adhesion, users are notified by a warning or an alarm via status outputs. If replaceable electrodes are used, they can be removed and cleaned if adhesion occurs.
