pierflow

Purpose:

Monitor a pierburg PLU126 flowmeter.

Enter:

pierflow <device_name> <temp_label> <density_label>

Where:

device_name	Specify the base filename of a configuration file in the /specs directory with the ‘.cfg’ extension. Do not include the ‘.cgf’ extension in the device name. This file is an ASC configuration file defining the serial communications interface and the expected commands and responses for the device.
temp_label	Specify the variable label where the temperature results will be stored
density_label	Specify the variable label where the density results will be stored.

Example:

pierflow pf pFuelTemp pFuelDensity &
The above command launches the pierflow task, and places the temperature into pFuelTemp and the density into pFuelDensity every second. The units of temp must be [deg_C] and the units of density must be [g/cm3].

Notes:

The expected message string from the meter will look like:

T = 30.1 < C > d = 83.3 < G∕CCM >< CRLF >
