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.

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.

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

  • 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.
