FlowControllerDriverBase

class FlowControllerDriverBase

Bases: ABC

Vendor flow-controller driver contract. Concrete drivers own their transport and lifecycle.

Attributes

mass_flow	Current mass flow reading.
pressure	Current pressure reading.
process_value	Current process value (primary feedback measurement for control).
process_value_source	Key constant (e.g. MASS_FLOW_KEY, VOLUMETRIC_FLOW_KEY, PRESSURE_KEY) indicating which measurement is the process value.
setpoint	Current setpoint in the device's configured engineering units.
volumetric_flow	Current volumetric flow reading.

Methods

close	Close the underlying transport.
get_flow_data	Read a full measurement frame from the device.
open	Open the underlying transport.
select_working_fluid	Select the active working fluid by name; driver resolves the device-internal identifier.
set_setpoint	Command a new flow setpoint in the device's configured engineering units.
tare_flow	Zero the flow reading.
