DF-210A Flow Meter

The DF-200 series compact flow meters are ideal for use in vehicles. A low profile with 3 cm thickness provides easy installation on the dashboard of a vehicle. The DF-210 measures instantaneous flow and accumulated flow in high resolution in combination with FP-2140H / 2240HA flow detectors.
The DF-211 extended unit provides additional onboard measurement capability such as pressure, temperature, and elapsed time.

Features

Ensure high resolution in flow data in combination with the FP-2140H/2240HA
Easy installation on the dashboard of a vehicle, with compact and light weighted design
The extended unit can expand measurement capability such as pressure, temperature and elapsed time
2 ways of power operation by DC and battery when the optional battery box used

*1    DF-211A is required when the detector, FP-2240HA/2250H, and MF-2200/3200 are used.
*2    Specifications shown in the above table, related to place on a display and pulse output,
        are applicable to the detectors; FP-2140H/2240HA, and MF-2200/3200.
        When FP-213S/213 used, spec. described should be multiplied by 0.1.
        In case of FP-215/2150A, spec. described should be multiplied by 10.
*3    For analog output, specification of 0 to 10V/0 to 100 l/h is for FP-213S/213/2140H/2240HA,
        and MF-2200/3200.
        Specification of 0 to 10V/0 to 1000 l/h is for FP-215/2250A.
*4    Accumulated flow values can be stored by the battery backed memory when power off.
