  • Visibility: White background provides better float visibility for easy and accurate reading, even in low-light or demanding settings.
  • Temperature and Pressure Rated: Operates up to 145°F and 100 PSI, making it suitable for a wide range of industrial and environmental applications.
  • Connection Options: Available with 1/2” Male NPT or 1/4” Female NPT threaded connections for versatile integration into different systems.


The PRM DFA-15T Rotameters are designed for services in the environmental remediation and industrial process markets. PRM has found through experience that other rotameters break, leak, and fail in the harsh conditions of the remediation industry, so PRM manufactures these standard flow control rotameters with a heavier duty body and mounting bosses to make the rotameters stationary and prohibit flexing. PRM rotameters uses a Stainless Steel valve assembly instead of brass, which is a typical failure point in harsh conditions. White background allows for better visibility of the float increasing reading accuracy.

Maybe i missed it some place but this is not for pressure over 90 psi , mine broke , the top lid cracks and leaks so i had to jb weldmine back together , hope it works but it was giving us bad reading the entire time so cost us thousands becuase we gotta run all those test again. This is good for child's science project or a cool looking paper weight
