On-Board Digital Flow Meter
DF-210B Flow Meter
The DF-210B / DF-211B are small-size, light weight and a low-profile with approx. 3 cm thickness flow meters designed for use on vehicles. The DF-210B measures instantaneous flow and accumulated flow with high resolution at 0.01 l/h in combination with FP-2140H / 2240H Positive-displacement Flow detectors. The DF-211B Extension Unit provides additional function to display the pressure, temperature, and elapsed time on-vehicle measurement. Portable battery box, DF-021A, is provided as an option, which is used to supply power to both units using its internal dry cell in case that the enough power supply is difficult on vehicle.

*1 DF-211B 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, specification. described should be multiplied by 0.1. In case of FP-215 / 2250A,
specification. described should be multiplied by 10.
*3 For analog output, specification of 0 to 10 V / 0 to 100 l/h is for FP-213S / 213 / 2140H / 2240HA,and MF-2200 / 3200.
Specification of 0 to 10 V/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.
*5 N.A.: Not Available.
