On-Board Flow Meter
DF-2200
The DF-2200 On-Board Flow Meter is a compact on-board fuel flow meter developed for our FP series Volumetric Flow Detector. It accepts pulse signal SIG A and SIG B that have phase differences, and includes the backward flow correction function for back-flow.
Displaying and measuring the mass flow rate is possible by entering the value of standard density of the fuel in use, and its temperature and density coefficient (1/°C). Besides the flow rate, the items of time/ temperature (resistance temperature detectors)/ pressure (voltage input) can also be measured.
The DF-2200 outputs the voltage corresponding to the value of instantaneous flow rate/ temperature/ pressure, and outputs the pulse corresponding to the instantaneous flow rate. CAN and RS-232C (option) are also equipped with the external devices as a communication function.
This is the flow meter that is capable of not only on-board measurement but also measurement on engine bench.
Features
The flow rate/ temperature/ pressure can be measured with just one unit
