19: Fluid Flow Computations

Command	Purpose
avl_link	Link to the AVL Indicom combustion analysis system.
blend_scales	Manage fuel weighing operations using load cells, including controlling fill valve operations and computing fuel rates based on sampling processes.
change_res	Change the formatted resolution of a variable or a list of variables.
cf_scales	Perform control functions for a load cell fuel system integrated with a continuous flow meter and flow control valve. The program manages fill valve operations, calculates flow rates, and processes fuel readings, outputting consumption rates and error statistics.
cfv_1065	Compute air mass flow on a continuous basis per the 1065 standard using inputs from a specification file.
critical_flow	Compute air mass flow on a continuous basis.
dummy_fr	Simulate fuel reading events by processing an event name to mimic the behavior of a fuel reading device task for testing purposes.
emcon_comm	Communicate with an AVL EMCON6 system to manage dyno control, handling data exchange via sockets, parsing configuration files, and processing input and output variables.
fa_total	Perform continuous fuel and air flow totalizing computations for engine performance, including summing rates and calculating metrics like air-fuel ratio.
fr_log	Set a fuel reading log file name.
gas_blend	Compute the ratios of three input gas streams to achieve a specified heating value and methane number for the resulting mixture.
gas_distribution	Set the values of CyFlex array variables that contain information about emission gases and perform actions based on cylinder states.
gas_mix	Compute the gas composition of a stream produced by mixing two or more gas streams, using the composition and mass flow of input streams to determine the mixed stream’s composition and mass flow.
gasfl	Compute gaseous mass flow rates for up to 8 meters based on input specifications.
generic_scales	Perform control functions for a directly controlled load cell fuel system, including fill valve operation, timing of fuel readings, and computation of consumption rates with error statistics from linear regression.

lc_scales	Control a load cell fuel system, managing fill valve operations and computing fuel rates based on measurements.
lfe	Compute gas mass flow rates continuously for a Laminar Flow Element based on specified inputs and configuration.
net_fr	Request a single fuel reading and set the fuel weight.
oil_scales	Measure the oil consumption rate using a load cell-based system by managing filling operations and computing rates based on measurements.
scales	Control the fuel scale system by managing fill valve operations, weight selections, and timing for fuel readings based on transition events.
subsonic	Compute continuous gas flow rates for subsonic venturi meters based on inputs from a specification file, performing real-time calculations and handling events for updates.
take_auto	Request a single fuel reading with automatic weight selection.
take_autos	Request continuous fuel readings and set the fuel weight selection to automatic.
