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.

Options

  • DF-021  Battery Box can supply power to both the DF-210A and DF-211 units.  Operated by 8 pieces of type SUM2D battery, with life time of approx. 8 hours for the DF-210A and 4 hours for DF-211A by an alkaline manganese battery.

  • DF-022  Remote Box provides remote control of the DF-210A/211A.

  • DF-023/024/025  Thermal Insulation Units can prevent exposure to heat generated by the sun when the DF-210A and DF-211A are mounted on a vehicle dashboard.

DF-023   :  Signal unit mounting and installation (for DF-210A)
DF-024   :  Two units mounting and installation (DF-210A/211A or DF-210A/021)
DF-025   :  Three units are available for mounting and installation. (DF-210A/211A/021)
