Reliable, Easy to Install Hot Tap Insertion Meter.

ideal for accurately measuring liquids, compressed air and saturated steam. No moving parts and virtually maintenance-free once installed.

  • Removable Insertion/Extraction Tool. Aids in installation or removal in high pressure applications
  • Reliable measurement for steam and a variety of fluids. Heavy duty design engineered to stand up to the most abusive environments inside and outside the pipe
  • Reduced Maintenance Costs and Spare Parts. No internal o-rings or seals of any kind and absolutely no leak paths into the sensors or electronics. Our sensors do not touch the process fluid, which gives them an almost unlimited life span.
