driver and command-line tool for [MKS mass flow controllers](http://www.mksinst.com/product/category.aspx?CategoryID=406).\n\n\u003cp align=\"center\"\u003e\n  \u003cimg src=\"https://www.engineering-sci.com/images/editor/G-Series%20Thermal%20Mass%20Flow%20Controllers%20\u0026%20Meters%20with%20Fast%20\u0026%20Repeatable%20Performance.jpg\" /\u003e\n\u003c/p\u003e\n\nInstallation\n============\n\n```\npip install mfc\n```\n\nIf you want the older python2/tornado driver, use `pip install mfc==0.2.11` and review [this README](https://github.com/numat/mfc/tree/1af5162b67041c6b5d934a5ef5f1aea0c8a5731e).\n\nUsage\n=====\n\nThis driver uses the ethernet port *on the side of the device* for communication.\nIf you use this driver, you only need to provide power to the top ports.\n\n### Command Line\n\nTo test your connection and stream real-time data, use the command-line\ninterface. You can read the flow rate with:\n\n```\n$ mfc 192.168.1.200\n{\n  \"actual\": 4.99,\n  \"gas\": \"CO2\",\n  \"max\": 37,\n  \"setpoint\": 5.00,\n  \"temperature\": 27.34\n}\n```\n\nYou can optionally specify a setpoint flow and/or gas with e.g.\n`mfc 192.168.1.150 --set 7.5 --set-gas N2`. See `mfc --help` for more.\n\n### Python\n\nThis uses Python ≥3.5's async/await syntax to asynchronously communicate with\nthe mass flow controller. For example:\n\n```python\nimport asyncio\nfrom mfc import FlowController\n\nasync def get():\n    async with FlowController('the-mfc-ip-address') as fc:\n        print(await fc.get())\n\nasyncio.run(get())\n```\n\nThe API that matters is `get`, `set`, and `set_gas`.\n\n```python\n\u003e\u003e\u003e await fc.get()\n{\n  \"actual\": 4.99,\n  \"gas\": \"CO2\",\n  \"max\": 37,\n  \"setpoint\": 5.00,\n  \"temperature\": 27.34\n}\n```\n```python\n\u003e\u003e\u003e await fc.set(10)\n\u003e\u003e\u003e await fc.open()   # set to max flow\n\u003e\u003e\u003e await fc.close()  # set to zero flow\n```\n```python\n\u003e\u003e\u003e await fc.set_gas('N2')\n```\n\nThere is also `set_display`, which will only work on devices that support it.\n\n```python\n\u003e\u003e\u003e await fc.set_display('flow')\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnumat%2Fmfc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnumat%2Fmfc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnumat%2Fmfc/lists"}
