Danfoss PFM100 User guide

  • Hello! I've reviewed the user guide for Danfoss PFM100 Δp Tool for RA-DV, RA-N, RA-U, RA-IN Dynamic Valves . This document provides step-by-step instructions for preparing the valve, measuring pressure with the PFM100 tool, and optimizing pump settings. The guide covers various aspects of the process, including measurement types, and differential pressure checks. I am ready to answer any questions you may have regarding the device and its usage.
  • What is the purpose of the PFM100 tool?
    What is the first step in using the PFM100 tool?
    What should you do if the differential pressure (delta P) is not constant?
