Intellachart Measurement System

The screen shots pictured below is the procedure of the new Intellachart 32 EGM Integrator. The integrator actually takes 15 seconds resolution of a chart and sums up the data for one hour, the same way that EGM meters do. Doing the chart the same way that EGM does has the advantage of not having rounding errors of the 5367 integrator number for hourly breakouts, also allowing for recalculations for orifice changes and other recalculation needs without re-integration. The integrator has a motor drive that takes 1,411,200 calculations during the 360-degree rotation, and the encoders on the pen arms take 10,000 samples of the arc line from 0-100 % line.

With the advantage of EGM and Charts using the same data in the editor we can now store a graph of both, and with pasting and editing and hourly reads from both sources making comparisons simpler.

We have tried to make it very simple to use and make KEY STROKES as minimal as possible.

The above is a Setup shot of the Integrator Motor Settings and either two-pen or one-pen integration. Under normal operating setup the Encoder Multiplier should be a (4) four.

The above screen is where your meter numbers are filed. When you press the reset, this screen will appear and meter number in this screen will store the master data. This is for chart input

The above screen is the verification screen and the starting date that was from the last run chart with the starting date and time and the ending date and time. If it is different than the automatic setting, just change it to fit actual time off.

The above screen is a selection of how you want to process the chart, either one-pen or two-pen integration, temp or no temp. Also note the special functions of fast /slow clock correction and two speed. These are options you might or might not use.

Above screen is for inverted charts. You probably will not be using this as it is for very low pressure and differential charts. You can invert or reverse the pressure differential and temperature scales with this option.

The above screen is for the manual offsets of differential, pressure and temperature. Also sets up the ranges for the integration. The integrator uses the meter master to set the absolute or gauge pressure automatically using the pounds pressure and atmosphere correction.

The above 3 screens set the pressure base and default temperature. Once these screens are filled in and saved it creates your master data for that particular meter. You know longer have to make any changes unless the meter data changes and you make the change effective to date and time. The editor can and will recalculate data without re-integration. The Measurement Basis includes 1992 Gross, 1992 Detail, 1985 NX19 Standard, (Full and Methane), 1985 AGA 8 Standard and Full, 1985 Redlich-Kwong.

The above two screens are after integration and the 1st screen asks if you want to save file and has the first of 168 breaks the second screen has the last of the 168 breaks. After saving it will load directly in the editor portion where it will also do a graph of the integration and create an hourly volume, pictured in picture below.

The edit screen above allows you to make global recalculations. If something changes after integration, instead of reintegrating, you can make an orifice change and recalculate the hourly data from that hour forward to end of record.

After screens are filled the first time on the meter, with no changes the procedure would be calibrate integrator, enter meter number, verify time off, as time on is from last record, run chart and accept data. If no recalculations are needed or meter correction factors needed, print volume statement, or E-mail, or network the data.

Anytime you want to look at 6 months or a year or 6 hours very quickly of data in editor, just put in the meter number and graph the data.

The editor has built in archive capabilities. We suggest for speed, to archive data over a year old. If you need to look at the data over a year old it is simple to locate the archived file and load the data. The editor will display over two years of data on one screen graph. Select a shorter date span to look at the data in more detail.
