Case Study: Pharmaceutical Company Improves Air Flow Control With Conditioning Orifice Flowmeter

In the pharmaceutical industry, there are many tough and challenging applications when it comes to the production of various products. Precise measurements are required for control and accuracy throughout the production processes.

A pharmaceutical company recently installed new air handling units to monitor the precise air flow measurement into the production area for the coating process. The customer's new production unit contained four coating suites, each of which contained four coating pans (which resemble front-loading clothes washing machines). The coating suites are separated into three areas, with the central area being the coating pan. Thousands of uncoated tablets are loaded into a rotating drum and are constantly tumbled and rotated while a coating is sprayed in the pan. At the same time, sterile air is admitted under controlled mass flow and temperature conditions. Reliable and accurate flow measurement is required to distribute and control sterile air during the coating process.
