Packing Case Vent Monitor: DPVM
The Mueller DPVM packing case vent monitor provides a valuable visual indication of rod packing wear (reflected by pressure differential) in order to minimize fugitive emissions and avert catastrophic compressor failure. This unique device easily attaches to the packing case vent connection and registers gas leakage rates of 6 to 50 SCFH (+/-10%). To avert sudden failures, the DPVM integrates an external relief valve in the event rod packing leakage creates a pressure differential greater than 10 PSIG. Easily installed, the compact unit is no larger than the average lunchkit.
