Technoton DFM S7 Wireless fuel flow meter

DFM S7 and DFM D S7 – hardware tool for direct fuel consumption measurement and monitoring flow of liquids with 1.5 to 6 mm2/s kinematic viscosity, also used for recording engine operation time and fuel/liquid flow time.

Description

DFM S7 and DFM D S7 – hardware tool for direct fuel consumption measurement and monitoring flow of liquids with 1.5 to 6 mm2/s kinematic viscosity, also used for recording engine operation time and fuel/liquid flow time. DFM S7 wireless fuel flow meters are used in vehicle telematics (GPS/ GLONASS vehicle tracking), online monitoring systems of stationary engines, boilers/heaters, and as an stand-alone solution for fuel consumption monitoring.

The flow meters are based on S7 Technology, which ensures wireless data transfer via Bluetooth 4.X (Bluetooth Low Energy) to several devices using BLE-radio. In other words, the flow meters are operated in “advertising” mode – data is sent simultaneously to telematics units and GPS trackers, Bluetooth-displays, smartphones and tablets.

Technoton

Technoton

Technoton was established in April 2000, at the early stage of emerging market of automotive telematics and GPS tracking systems. We started with development and manufacture of GPS tracking devices, fuel level sensors and fuel flow meters. Soon we focused on solving tasks of fuel consumption measurement and fuel usage monitoring, safe CANbus data reading and analysis.

Technoton’s technical team includes highly-qualified engineers and developers, who have wide expertise in micro controller units, mechanical engineering, computer science, programming and diagnosis.

Features

  • operation in BLE-radio mode: data is sent to several Receivers at the same time
  • in-built battery – fuel flow sensor works without external power supply very low power consumption allows autonomous operation of flowmeter for 5 years
  • explosion and fire safety without additional intrinsic safety barrier
  • no cables – improved resistance to vandalism or accidental damage

Applications

  • Bus
  • Truck
  • Marine Vessel
  • Minning Vehicles
  • Diesel Locomotives
  • Agricultural Machinery
  • Diesel General Engine
  • Road Building Machinery

Additional Informations

  • Single-chamber (models DFM 50S7, DFM 100S7, DFM 250S7, DFM 500S7) – fuel consumption measurement in fuel feed line of engine. Can work both autonomously and as part of a telematics system. Designed for fuel consumption control of road, off-road and railway vehicles, water vessels, diesel generators and stationary machinery equipped with Euro-4 engines and lower, which have 1 to 500 L/ h flow rate.

Single-chamber flow meter with Blueooth

  • Differential (models DFM 100DS7, DFM 250DS7, DFM 500DS7) – measure fuel consumption as the difference in flow rates in feed and return lines of fuel system – differential consumption measurement from 10 to 600 L/ h. Designed for fuel consumption control of road, off-road and railway vehicles, water vessels and stationary machinery equipped with modern diesel engines, which has Common Rail or pump injector fuel systems.
