Python driver for Brooks Instrument mass flow controllers
Project description
mfc
Python driver and command-line tool for Brooks Instrument mass flow controllers.
Installation
pip install brooks_mfc
Usage
This driver uses an undocumented REST API in the devices's web interface for communication. The compatibility and stability of this interface with all Brooks controllers is not guaranteed.
Command Line
To test your connection and stream real-time data, use the command-line interface. You can read the flow rate with:
$ brooks-mfc 192.168.1.200
{
"Customer Flow Totalizer": 0.0,
"Flow": -0.3,
"Flow Hours": 1.0,
"Flow Totalizer": 0.0,
"Live Setpoint": 0.0,
"Operational Hours": 50.0,
"Setpoint": 0.0,
"Supply Voltage": 22.93,
"Temperature": 27.11,
"Valve Position": 0.0
}
You can optionally specify a setpoint flow with:
brooks-mfc 192.168.1.150 --set 7.5. See
mfc --help` for more.
Python
This uses Python ≥3.5's async/await syntax to asynchronously communicate with the mass flow controller. For example:
import asyncio
from brooks_mfc import FlowController
async def get():
async with FlowController('the-mfc-ip-address') as fc:
print(await fc.get())
asyncio.run(get())
The API that matters is get
, set
.
>>> await fc.get()
{
"Customer Flow Totalizer": 0.0,
"Flow": -0.3,
"Flow Hours": 1.0,
"Flow Totalizer": 0.0,
"Live Setpoint": 0.0,
"Operational Hours": 50.0,
"Setpoint": 0.0,
"Supply Voltage": 22.93,
"Temperature": 27.11,
"Valve Position": 0.0
}
>>> await fc.set(10)
>>> await fc.open() # set to max flow
>>> await fc.close() # set to zero flow
