FFM-1000

Overview

The HORIBA Fuel Flow Meter is comprised of two separate units:

Fuel Flow Measurement Unit (FFMU, Upper Cabinet)

This unit contains the coriolis meter, pump, heat exchanger, and all the necessary hardware and controls. The coriolis meter is the "heart" of the instrument, and the industry standard for fuel flow meters. This meter measures mass, and therefore requires no assumptions about density.

Fuel Temperature Control Unit (FTCU, Lower Cabinet)

This unit includes an electric heater and water chiller for controlling the fuel temperature and a booster pump to guarantee flow rates for the entire specified range of operation.

Controller - One controller (included with the FFMU) operates both units using JAVA software and a graphical user interface styled after the industry standard MEXA range of instruments. 

Optional Laptop - Displays and controls all of the operation and utility functions of the fuel flow meter as well as diagnostic screens and data logging.

Optional Pendant - Hand held pendant is useful for all equipment basic functions and includes buttons for standby, measure, purge, reset, alarm and an e-stop.  A five meter cable is included.
