Digital Flow Meter

FM-3100

Achieving high-speed output in response to changes in transient flow.

In the field of engine development, high precision in low flow rate measurement and evaluation of fuel consumption characteristics during transients are required.
The FM-3100 is a digital flow meter that outputs measurement data at high speed when combined with various detectors (FP, FX, FZ series, Fuel Density Meter).

Set accumulated time via CAN communication No.1

To change the Auto Stop total accumulated time from an external source, RS-232C communication was required, but it can now also be changed via CAN communication.
Since accumulated operations (such as Start and Stop) have been possible with CAN from the beginning, it is now possible to consolidate the necessary external communication to only CAN for applications where the accumulated stop time is switched for continuous testing, thereby simplifying the system.
Command 06: Accumulated time setting has been added. It is now possible to set the accumulated time from an external source. The Auto Stop accumulated time setting, which could only be changed through direct operation and RS-232C, can now be done via CAN.

Set accumulated time via CAN communication No.2

Using the CAN In ID (default value: 0x601), set the value,
and output command 06: set the accumulated time to the FM-3100 to configure the accumulated time.

Simultaneous output of volumetric flow rate and mass flow rate from analog output.

Regarding the analog output of the module specifications, it has become possible to use not only OUTPUT 1 but also OUTPUT 2 for flow measurement. This allows for simultaneous analog output of volumetric flow and mass flow.

Changes to factors in the FP series and changes to the output scale that affect measurement data will require a password.

If the Factor of the 'FM-0311 FP Module' or the Zero CAL and Low Flow Cut of the 'FM-0321 FZ Module' are changed, the date and time of those changes, as well as the new values, will be automatically saved for later confirmation.
