Flow and Thermal Energy Measurement in Pharmaceutical Production

Flow and Thermal Energy Measurement in Pharmaceutical Production

The production facilities and research and development labs of a global pharmaceuticals company have launched a program that provides several measures to reduce energy consumption (and thus CO2 emissions) by optimising production processes. The first step in an effective plan to reduce CO2 is to establish procedures for systematic recording of energy consumption.

With 90 buildings in an area of 36 hectares, the french site of the company forms a complex and extensive infrastructure network. Demineralised water and hot water are among the process media provided in a central system. In order to be able to measure their consumption by individual production units, the plant engineers decided to fit measuring points with clamp-on ultrasonic technology. The advantages of non-invasive measuring technology are obvious: 100% hygienic measurement from outside and no interruption to production when setting up measuring points. The engineers also wanted to avoid any possible pipe work, in particular on the hot water network where water circulates under pressure at temperatures of ~170 °C.

Before deciding on a provider, several clamp-on systems were tested and evaluated. The operator decided to go for FLEXIM based on the fact that even very low flow rates with correspondingly low flow velocities (<0.1 m/s) can be accurately detected. They were also convinced by FLEXIM's transducers which can be permanently used in process temperatures up to 200 °C.

Advantages

  • Reliable and accurate measurement of flow rates and thermal energy regardless of the conductivity of the medium
  • Measuring points can be set up without any pipe work or any interruption to production
  • 100% hygienic: no contact between measuring equipment and medium
  • No wear and tear caused by medium
  • Practically maintenance-free
  • Transducers for permanent operation at high temperatures
  • High measuring dynamics, accurate measurement even of the lowest flow velocities
