Introduction The following manual describes the Liquid Orifice measurement application for Totalflow XSeries and microFLO devices. The manual will cover the initial setup and testing of the application as it applies to certain Totalflow devices. Organization & Style Each of the chapters in this manual presents information in an organized and concise manner.
LIQUID ORIFICE OVERVIEW The Liquid Orifice measurement application is designed to operate in conjunction with a flow computer and measure liquid volumes for a given material. This application is available for both Totalflow XSeries and microFLO devices. This application is designed to perform calculations based on the standards determined in the API Manual of Petroleum Measurement Standards, Liquefied Petroleum Gas Measurement.
Figure 1 Application Tab APPLICATION DEFAULTS The user needs to move into the Flow Measurement application in the tree-view to view the parameter defaults. Click on the plus (+) sign next to the Flow Measurement caption to view the other available options within the Flow Measurement application.
3.1.1 Device Application ID The Device/Application ID is an alphanumeric string that is up to ten characters long. For single tube measurements, this represents the Station ID. The Station ID can be viewed or changed in the Station Setup tab under the top-level Station ID in the tree- view.
Linear average is calculated as the mathmatical mean of one- second samples over the log and day periods. Square root average is the sum of square root of one-second samples, squared, it is then divided by the number of samples. •...
Figure 3 Constants Tab 3.2.1 Barometric Pressure Barometric Pressure (PSIA) is a floating point number that represents the barometric pressure. Enter the current barometric pressure within the corresponding field. 3.2.2 Dp Zero Cutoff Dp Zero Cutoff (In H20) is a floating point value that represents the lowest expected non-zero differential pressure reading.
3.2.4 Orifice/Pipe Diameter (inches) The Orifice and Pipe Diameter fields allow the user to set the orifice and pipe diameters. These are entered as floating point values, as measured in inches. Changes to the pipe and orifice will cause significant changes to the flow rate calculation.
If ( gb < 0.5 ) VCF = 1.0. If K0, K1 and K2 factors are all 0.0, VCF = 1.0. Table 1 shows recommended liquid type, gravity range and VCF k factors. Table 1 Recommended Liquid Type Liquid Type Base Gravity Range Crude oils (2) 0.611 –...
Figure 4 Limits Tab 3.4 Commands Tab The Commands tab (see Figure 5) shows the Reset Volume, Reset Log Period and Site Code entries. Figure 5 Commands Tab 3.4.1 Reset Volume When set, the Reset Volume field accomplishes four tasks: •...
3.4.3 Site Code This is a user set, floating point value that is logged in the application event file. Negative value site codes are caused by the application. As this is the case, it is recommended that positive values be entered in by the user. 3.5 Log Capacity Tab The Log Capacity tab (see Figure 6) contains settings for the log period, day period and event records to save before overwriting the oldest.
Figure 8 Calibration Setup Screen The static pressure, differential pressure and temperature registers must be set to I/O or XMV registers to allow for calibration. 4.1 Calibration Checks Tab The Calibration Checks tab (see Figure 9) allows the current measured values to be tested and logged as events when they are compared to a known benchmark test.
If the user chooses to move to the Events Collection view, they will be able to see the Dp calibration check event, as entered. Additionally, the user can use the drop-down menu to select Dp, Sp, Tf or DP & Sp. By entering these values, the user will log the values into Events the event log.
* These screens and tests apply to the Liquid Orifice Tube Measurement application that is running on G3, XFC and XRC. 5.2 Verifying Configuration The following test requires that a liquid measurement tube be enabled and configured correctly. Holding registers also need to be enabled within PCCU. 1) Within PCCU, click on Holding Registers.
Figure 12 Setup Tab 8) Move back to the Current Values tab within the Flow Measurement application, and note the DP, SP and Tf values. These values should be the same as the ones that the user just established. 9) Next, move to the Commands tab within the Setup tab on the Flow Measurement application, and perform a reset volume.
