Digital Flow Meter FM-3100 New
Achieves high-speed output responding to transient flow changes
In the field of engine development, it is increasing the requirement for improving the accuracy of the measurement in the small flow rate range, and evaluating the fuel consumption characteristics in transient duration. The FM-3100 enables to meet various requirements in that field.
Feature
1. High-speed response at 1 ms (Analog/ CAN)
It captures transient flow rate changes and provides signal output either analog or CAN at 1 ms cycle. It is suitable for checking the rise of the instantaneous flow rate and measuring the fuel flow rate during transient mode.
2. Applicable to various detectors
It connects to FP series Volumetric Flow Detectors, FX series Mass-Burette Flow Detector and FZ series Coriolis type Mass flow Meter.
3. Equipped with the density correction function which corrects density based
on a temperature value
The FM-3100 has the function to compensate the density based on the calculation of the temperature fluctuation between a fuel density meter FD-5110 and a flow detector even if each measurement positions are separated, which enables the accurate mass flow measurement.
