Chapter 1 - Introduction What is the TeleFlow™ Standard ACCOL Load? The TeleFlow™ Standard ACCOL Load is included on the TeleFlow™ diskette. This ACCOL load contains ACCOL modules specifically configured to perform various natural gas calculations using a standard I/O setup. It is discussed in detail in Chapter 2 of this manual.

Chapter 2 - TeleFlow Standard ACCOL Load Overview The TeleFlow Standard load is a an ACCOL load (ACL file) that is intended for use in the EGM 3530 TeleFlow. This ACCOL load will compute gas flow rate, energy rate and volume and energy totals for a single Orifice meter run. Flow calculations and data storage will be done according to the requirements of Chapter 21 of the American Petroleum Institute Manual of Petroleum Measurement Standards (MPMS).
Chapter 2 - TeleFlow Standard ACCOL Load " " " " " Configurable 1, 2, 5, 15, and 60 second calculation interval. Pulse counting and scaling. Configurable automatic dial-out on alarm occurrence. (NOT YET SUPPORTED) Control of an external radio. Battery charge regulator. NOTE: The EGM 3530 only supports a subset of the ACCOL module library thus some ACCOL modules will not operate.
Chapter 2 - TeleFlow Standard ACCOL Load obtained by summing the Extensions computed every second during the interval and dividing by the number of Extension values summed. The Extension sum is then cleared and averages are reset for another Calculation interval. There are several conditions, which force the Calculation interval to be 1 second as follows. 1. When the Local communications port is in use. 2. When the LCD Display is active (i.e scrolling data for the operator). 3.
Chapter 2 - TeleFlow Standard ACCOL Load Input Override and Calibration Mode The 'in use' signals can be 'frozen' at their current value by setting their standard ACCOL Control Inhibit (CI) on. When an 'in-use' signal (DP, P, or T) is in 'CI' mode, the 'live data' signal continues to reflect the current value from the internal sensor, however, the 'in-use' signal is no longer updated and remains 'frozen' at its current value.
Chapter 2 - TeleFlow Standard ACCOL Load When Sampler output is enabled: DO 1 - Pulse output based on volume (to drive an external totalizer or sampler). DO 2 - general-purpose output. Sampler logic has a default volume of 100 mscf and a default pulse width of 1 second. Flow control has priority for the discrete outputs so that if both Sampler output and Flow control are enabled, Sampler will be shut off and Flow control will use the outputs.
Chapter 2 - TeleFlow Standard ACCOL Load Communications Port Assignments PORT #1 - Pseudo-slave local port, 19200 bps. PORT #2 - BSAP network port, 9600 bps. The baud rate and the RTS/CTS delay may be changed on-line. Communication Port Usage The Local port is used for local configuration and data collection. It usually connects to a PC or Laptop that is running a user-interface software package like TMS or UOI.
Chapter 2 - TeleFlow Standard ACCOL Load The flow control is active and not close to the setpoint. Super-compressibility (Fpv) and Compressibility ( Zs, Zb, Zf) When the 1985 AGA3 calculation is selected, the Super-compressibility (Fpv) value is calculated using the NX-19 equations. When the 1992 AGA3 calculation is used the Flowing (Zf) and Base (Zb) compressibility factors are calculated using either the AGA8Detail or AGA8Gross module. The AGA8Gross module provides either the G,C,N or HV, G, C modes.
Chapter 2 - TeleFlow Standard ACCOL Load the total cleared for the next period. The running total is not cleared; it accumulates to 10 million at which point it rolls over to zero and continues accumulating. Averaged Extension The average value of the Extension ( square root of the product of process DP and absolute Static Pressure) is computed for each log period (hour or 15 min) and for the day and saved in an archive.
Chapter 2 - TeleFlow Standard ACCOL Load Low-Flow Cut-OFF The 'live' Differential pressure is always compared to a CUTOFF signal set in inches of water. When the DP value drops below the value of the CUTOFF signal, flow calculation will cease and the calculated flow-rate will be zero. Default cutoff is 0.25 inches of H2O. Flow Time While the DP is above the Cutoff limit the unit will accumulate a flow-time count in minutes for the hour and day.

Radio Scheduling is used to conserve battery power by allowing the radio to be powered up for a short time every day in expectation of receiving a message from a remote 'host' during that time.
Chapter 2 - TeleFlow Standard ACCOL Load commands sent to the modem (i.e. initialization, phone number) are defined by signals in the Dial list. The use of the modem dial out function implies that the called device has been set up to 'know' that it should poll for alarms after it answers the call and then hangup. Dialing logic will dial the first phone number three times and then dial a second number three times, the combination constituting one 'dial-attempt'.
Chapter 2 - TeleFlow Standard ACCOL Load Audit/Event Log The EAUDIT module (in Task 0) is set up to collect both alarms and events, with event signals defined by the signals in list 23. The module is defined with enough space for 400 alarms and events, and the module operates such that 200 alarms and 200 events are kept separate until the Audit log is collected. This design prevents a toggling alarm or event from filling the entire alarm/event log buffer to the exclusion of all other entries.
