alicat_massflow

Purpose:

Start communications with Alicat Scientific Mass and Volumetric Precision Gas Flow Controller 1500 SLPM model. It reads the volumetric flow and mass flow of CO2 once every second. Allows a set-point from 0 SLPM to 1500 SLPM full scale flow.

Enter:

alicat_massflow

Where:

N/A

Example:

alicat_massflow &

Notes:

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

The ASC configuration file “/specs/alicat_mf.cfg” file must exist.

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

The following variables will be created if they do not exist:

REAL

alicat_press Press measure by device in PSI_A
alicat_temp Temperature measured by the Device in C
alicat_co2_vf CO2 volumetric flow
alicat_co2_mf CO2 massflow
alicat_mf_rate Current massflow rate
alicat_setrate_mf Value to set the massflow rate when the alicat_sp_cmd is received

The following event will be created by the application and will be set if there is a comm loss: 
alicat_comm_loss

The following event will be created by the application and is used to signal the application to set setpoint flow rate:
alicat_setpoint
