An appropriate control and measurement system is one of the elements that allows for the safe and effective operation of a technological installation. Such a system may have a diverse structure that corresponds to the expectations and needs of its user. The devices of various manufacturers, including PLC (programmable logic controllers), can be used as a source of measurement data. This enables flexible measurement-control installations, which are adapted to the technological installations, to be built. This paper presents a system, which was created by the authors, for monitoring the temperature, pressure and flow rate of fluids. It uses the operational and IT properties of the PLC and is adapted to an existing installation on the test stand for multiphase spraying processes. In addition, as a part of the research, an application written in Python language, which allows collected data to be displayed, stored and exported, was implemented.
适当的控制和测量系统是确保技术设备安全、有效运行的要素之一。这样的系统可以具有多样化的结构，以满足用户的期望和需求。包括可编程逻辑控制器（PLC）在内的各种制造商的设备都可以用作测量数据的来源。这使得可以构建灵活的测量控制系统，这些系统可以适应技术设备。本文介绍了作者创建的一个用于监测流体温度、压力和流量的系统。它利用了 PLC 的操作和 IT 属性，并适应于多相喷涂过程测试台上的现有设备。此外，作为研究的一部分，还实现了一个用 Python 语言编写的应用程序，该程序允许显示、存储和导出收集的数据。
