Micro Motion® 820 Electronics
The 820 Electronics module is the right fit for the fuel measurement application and has Emerson�s Adaptive Consumption Measurement software added.
This electronics module allows for two flow meters to be connected to a single source and therefore provides a 4 to 1 reduction in electronic components. This solution improves the signal processing speed between the supply and return measurement points, ensuring an accurate instantaneous consumption calculation.

Remote mounting options


  • The design provides an exceptional combination of accuracy and reliability.
  • Contains a security lockout switch to provide physical and software security.
  • All the serviceable electronics are in the 820 enabling flexibility regarding installation locations.
  • The 820 electronics are targeted for marine fuel consumption applications including main engines, auxiliary engines, boilers, among others.
  • Supports the patented Adaptive Consumption Measurement Software, which provides an accurate differential measurement at all times.
  • The service port makes it possible to perform diagnostics and configuration without loss on measurement.
  • Through the Adaptive Consumption Measurement software, the 820 transmitter eliminates the need for secondary control system to determine consumption in engine systems. With the multi-variable Coriolis measurement the software allows for flexibility with output units, mass or volumetric units, eliminating the need for complex conversions.
  • Replaces both transmitters and combines both core processors in a single device, reducing installation time, cables and footprint.
  • Reduces installation complexity.
  • System can operate and measure accurately with dual fuel systems. There is no need to adjust the measurement system during fuel switching processes.
  • Live density measurements and outputs can be used to support Fuel usage and reporting.
