Fuel Level Senders – The inside Scenario.

Other

It goes without saying that each and every piece of gear which is powered by an internal combustion engine requires a means of fuelling so it runs for as long and efficiently as possible. ICEs are used in automobiles, motorcycles, race vehicles, ATVs, utility vehicles, compressors, generator sets etc., to name but a few, and the issues which has always pertained are how to contain the fuel, know how much is left and how it should be kept for the user’s benefit, safety and safety.

Fuel containers are typically plastic or steel because these substances have traditionally been used and are relatively inexpensive, but many modern race fuels comprise some very aggressive additives so these tanks will need to be made from carbon fiber or be reinforced with Kevlar. Truck and lorry fuel tanks are usually rectangular in shape that allows easy fitting of a simple swing arm type fuel level sender because there are few baffles or strengthening struts to slow the sender’s float arm. This sender outputs an ohmic value usually to some judge but suffers from underlying failures caused by fuel slosh which causes the immunity track to be continuously wiped by the float arm and so reduce the sender’s service lifetime.

Modern vehicle designs require that the designer needs to be inventive is adapting the profile of the tank to not influence upon the increasingly complicated aesthetics of the vehicle fuel level sensor suppliers. The swing arm sender is unsuitable for this type of tank which therefore allows using solid state electronics sensors and senders that can be programmed to the tank and give precise readings of the fuel level. Additionally, sophisticated electronics engine management systems now need voltage or PWM (Pulse Width Modulated) inputs unavailable from the swing arm sender. Accordingly, the capacitance level sender is an perfect product for replying all of the technical demands because there are no moving parts to wear out; capacitance technology is reliable and well known; the sender’s outputs match all analogue and digital ECU inputs; it may be programmed to compensate for irregular tanks shapes and to smooth out blips caused by fuel slosh and has many other characteristics.

The last few years have seen the price of fuel escalate to some point where its theft is currently a major factor from the processes used to secure the tank. One often used way is to get the fuel filler neck placed behind a lockable panel along with a second means is to match a anti bacterial device. Furthermore, the designer may specify fitting a capacitance fuel level sender which can output the level to a remote monitoring telemetry system so regular readings of fuel level can be listed and if a sudden drop in level be detected, this may indicate fuel theft as well as also the cause of the reduction be investigated quickly. In addition, in a vehicle application the fuel consumption may be measured correctly and provide information which shows whether it is being pushed in an economic and appropriate manner.
