Introduction

The Operation Manual contains guidelines and rules which refer to DFM fuel flow meters

(hereinafter DFM), developed by JV Technoton, Minsk, Belarus.

The manual contains information on design, operation principle, specifications and

instructions on installation, use and maintenance of DFM. The manual provides guidelines

on DFM configuration with Service S6 DFM software (version 1.11 and higher).

— is a precise tool for fuel consumption measurement. DFM can be

as a part of Teleamtic System or as stand-alone solution.

DFM features:

 unique self-diagnostics feature to monitor the stability and accuracy of data*;

 possibility of integration into on-board Telematics Interface of vehicles**;

 embedded battery allows data (Counters, Events) storage in the internal non-volatile

memory of flow meter;

 thermal correction function with adjustable coefficient which ensures automatic cor-

rection of values to the ambient temperature***;

 easiness of flow meter configuration with S6 SK service kit, which is similar for all

Onboard Equipment based on S6 Interface***;
