#FAQ
-
Q: How do I choose the right frequency for my gas meter?
A: 100KHz offers wider beam angle and good penetration for larger meter bodies. 200KHz/220KHz provide higher resolution and a more focused beam for compact, high-accuracy meters. -
Q: What is the advantage of the PEEK/NBR housing?
A: It provides superior resistance to corrosive gases and moisture, making it essential for meters used in harsh environments or with special gas compositions.
