OTC 2019 will be here soon! Come see us, May 6-9, at Houston's NRG Park! Stop by our booth and check out our highly durable level sensors and pressure transducers, which are ideal for all your off-shore measurement needs. Learn more about our sensors and high-five our knowledgeable staff!

We manufacture high quality, long lasting level sensors and pressure transducers for a variety of off-shore and general exploration and drilling applications. Examples include:

  • Mud Logging and EDT
  • Measurement While Drilling
  • Oil-Water Interface Level Measurement
  • Dual-Level Tank Monitoring
  • Pump Skids
  • robust sensors for harsh chemical environments
  • telemetry
  • CSA, ATEX, and IECEx hazardous locations


Hammer Union Pressure Transducers

Our hammer unions outlast and outperform the competition. With all-welded construction from NACE materials, vibration protection, and hazardous location certifications from CSA, ATEX, and IECEx, APG hammer unions give you the precision measurements you demand, in the tough environments where you need them.
