* – only specified length ranges for DUT-E 232 and DUT-E 485 DUT-E Application for Fleet Monitoring DUT-E has a standard 5-bolted flange and can be installed either in a place where the standard fuel meter is situated or in a separate aperture in the fuel tank. All necessary details for the installation and sealing of DUT-E sensor are present in DUT-E mounting kit.It is recommended to install DUT-E in the geometrical center of a tank.After the installation of DUT-E is complete, you must perform tank calibration. A calibration table is built in the process, where the output signals of the sensor correspond to correct fuel levels in the tank. This table is used by a fuel monitoring system to determine how much fuel is in the tank. DUT-E 232 and DUT-E 485 are able to calculate fuel volume by themselves (either in liters or in per cent values of full tank) and send this data in an output message. To do this, the calibration table must be saved in the memory of the sensor using the SK DUT-E service kit. DUT-E fuel level sensor transmits the data about the current fuel level to a GPS tracker. The fleet monitoring system determines the place and the time of this transmission using GPS. The user will get the information about events and the parameters of the vehicle in a form of graphics and tables.

Differential fuel flow meter DFМ is designed for diesel fuel consumption measurement in the fuel line of vehicles and installations. Differential fuel consumption meter DFМ may be used both with vehicle tracking system and fuel monitoring system installed on motor vehicles with modern EURO (TIER) 3/4/5 diesel engines. Differential fuel meter DFМ is used to measure the fuel consumption of vehicles, where it is not possible to apply the single-chamber diesel meter and the installation scheme with the return fuel line ringing.

Operating principle The operating principle of differential diesel meters is to calculate the fuel consumption as a difference between the flow rates in supply and return fuel lines of the engine. Differential fuel consumption meter DFМ consists of two three-dimension ring type measuring chambers. Each chamber generates the impulse, when the volume of fuel (which is equal to the measuring chamber volume) passes through it. Electronic scheme is responsible for the impulses deduction and output impulses formation. For the 1 liter of consumed fuel DFM generates the number of impulses, which is marked on the meter harness.
Mounting
Differential fuel flow meter is mounted into the fuel line of a vehicle without changing the fuel system scheme. Differential diesel meter DFМ can operate with GPS trackers which have discrete or pulse input 0-32V, for example, with dаta logger CKPT 31 Lite, vehicle tracking device CKPT 45.
Warranty Warranty period for fuel flow meters is 18 months from the date of installation or 24 months from the date of manufacturing.
