Flow Meter DE

Flow Meter DEFlow 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 DE style meter has an LCD display that shows the current volume, the current flow, and date. The normal display indicates current volume (ft3). The following values can be recalled from this normal state by pressing the blue pushbutton located on the top of the display head:

  1. Key-date value (ft3/a) indicates the volume consumed since the key date. The key date value function stores the total volume consumed annually from key-date to key-date. This feature allows you to determine the volume consumed in the current year at any time, for example: Total consumption since the meter was installed (Normal Display): 309,560 ft3 Key-date value (through the end of last year): 300,000 ft3. This means 9,560 ft3 was consumed since the last key date.
  2. The key date indicates the date from which the volume displayed in Menu 1 was consumed. This value is saved in the key date value (factory set at: December 31, this can only be reset or changed at the factory) Default status: 00-00, will be displayed on December 31.
  3. The Instantaneous flow (ft3/h), indicates current flow.
