BusLogic Capacitive Fuel Level Meter

BusLogic capacitive fuel level meter - used for a capacitive measurement of the level of fuel (and other liquids ) in tanks ,pools, tanks and other liqud storage areas in which they can perform measuring. DLKMG can be used on all types of vehicles, body length of the probe is adjustable as well as all the seals and mounts, so that it can be adapted for any type of tank . Probe body is made of high quality aluminum alloy in combination with sealing elements made of polypropylene and rubber seals made of oilproof rubber that provides stable operation and high resistance to corrosive action of fuel and other substances which measurements are taken.

Measurement accuracy of the fuel gauge is far greater than one achieved with a conventional level meters which relie on a mechanical level measurement of liquids (fuels ). Also, its unique design makes it more accurate than most of the capacitive meters on the market. Thanks to the accompanying software it is possible to perform precise analysis of data and present it in form of graph of consumption in real time , with the possibility to analyse individual points which show sudden drop in the fuel level .

DL capacitive fuel meter is offered in several versions , the basic version consists of the gage body and the standard measurement electronics , other versions may contain the installation of optionall built-in G - sensor and temperature meter, as well as wireless communications and battery power . Capacitance meter which has a temperature gauge and G - sensor have the ability to detect angle and turbulence of fluid eliminating the influence of temperature and movement / position of the vehicle on the accuracy of the measurement. This is of great importance for the buses in which , due to frequent breakdowns of air shock absorbers, vehicles often run under a certain inclination. Without proper G - sensor this inclination can cause the lack of accurate fuel readings .

If using version of the fuel meter which is capable of wireless RF communication with the rest of the BL system of the vehicle, it is also possible to use compact battery power when BLCFLM works completely without wires . Wireless RF connection is extremely important to communicate with refueling pump if it is also integrated into BusLogic system . That way it is possible to control the pouring of the fuel in vehicle and dispensing from pump in real- time . If discrepancy appears in the flow of fuel from either side , pump is stopped automatically.
