vaisala

Manage communication with a Vaisala RH meter, process responses, and update specified CyFlex variables with data such as vapor pressure, relative humidity, and stream temperature.

Enter:

vaisala <device> [vap_pa] [rh] [gas_t] &

Where:

device	Specify the device name to communicate with. This is the base file name of the configuration file.
vap_pa	Optional. Specify a CyFlex variable label for vapor pressure. This should have units of pressure.
rh	Optional. Specify a CyFlex variable label for relative humidity. This should have units of percentage.
gas_t	Optional. Specify a CyFlex variable label for stream temperature. This should have units of temperature. If specified, this must be the fourth argument.

Example:

vaisala vaisala VS_vap &
Save only the vapor pressure

vailasa mydevice myvap myrh mytemp
Save the vapor pressure, relative humidity, and stream temperature

Notes:

This command is normally placed in /cell/go.scp so that it runs all of the time.

A copy of the vaisala.cfg file is located in cyflex/specs.def at CTC and in cyflex/specs.def at “cmxnode1”.
