This armored purge meter operates over a 10:1 range. Scales are 1 1/4 inches long. The 1/2-inch meter has a gph or scfh scale; the 3/4-inch meter, a gpm or scfm scale. Each has a percent scale also. Construction with such materials as nickel-plated carbon or 316 stainless steel with Buna-N, TFE, and 321 stainless trim give maximum corrosion resistance. |
