  • Improve Bioreactor Performance by Using Mass Flow Controllers
    . The rotameter PDL had been using was not adequate for measuring the low flow rates needed to prevent excessive foaming. "We now have a high degree of confidence in our flow rate," says Sauer. "When we were using rotameters to control our flow rate at the lower edge, we experienced a substantial

  • High Throughput Leak Detection
    . This problem is made worse by the fact that the uncertainty is greater for large leaks. For these reasons, it is essential to use a flow meter designed to operate with a very low pressure differential. Instrumentation Choice. The recommended mass flow meter is the Hastings HFM 300. It is chosen for its
