Flow Meter DM

Flow Meter DM-NFlow Meters DE and DM are designed to measure volume (DM, DE) and instantaneous flow (DE) of natural gas, propane, inert gases, and air. Typical applications include secondary measurement of volume on industrial installations and test stands including furnaces, kilns, and ovens used in all types of heating processes. The flow meters are ideal for monitoring gas flow rates that aid in optimizing fuel consumption, and providing important troubleshooting information.

The total volume is indicated on the mechanical counter head. A remote indicator can be operated with one or two incorporated pulse generators (round plug 3-pin to DIN 41524).

Features

  • Measurement of the instantaneous flow (DE) and volume (DM, DE) of gas and air
  • Turndown range up to 20:1
  • Connections for optional sensing equipment
  • Arbitary mounting position
  • Compact design
  • Maintenance-free
