A leading, globally operating company develops, produces, and distributes compressors for cooling circuits. The compressors are used in refrigeration and freezing engineering, for private applications, in commercial small cooling systems, and as direct current compressors for mobile applications. Sustainability, resource conservation to the greatest possible extent, and reliability are important considerations for the company’s manufacturing
operations – including the in-house paint shop.
A KEM Turbine Flow Meter (HM F Series) with flange connections, tungsten carbide hard metal bearings, and stainless steel housing as well as a Local Display with carrier frequency pickup (VTC).
The final black coating is applied to the compressors in the paint shop. In this process, the contents of the coating bath are permanently circulated through a filter system. A flowmeter used for precise coating bath monitoring checks the system state and plugging of the filter. The existing measuring equipment was to be replaced by a highly reliable and durable flowmeter with a better measuring accuracy. Specific challenges included fitting the device to the existing flange connections and the relatively short up and downstream sections in the piping system. An easy to read display suitable for the installation situation and an electrical interface for the process control connection were also required.
