How accurate is my gas gauge and fuel computer?
I have a 98 Ford Explorer with a gas gauge that will fluctuate a quarter tank depending on the surface I'm driving on (uphill, downhill) It also has a fuel computer (I don't really know what it's called) that tells me how many miles till empty, how many gallons left, etc. I've heard those aren't alway reliable and I'm afraid to trust my gas gauge also.
I was once parked in my boyfriends driveway (downhill) and couldn't start my car, even though it said 72 miles and 4 gallons left. Is this an abnormal amount of fluctuation for a car? I get nervous whenever I get below a quarter tank. The needle will be just below a quarter tank and next thing I know it's down below the E.
This is a tough one as there are so many varying factors.
1. Being on a slope will "fool" the Gauge and computer as to the actual amount of fuel you have.
2. The vehicle may not have started due to the pipe into the tank not being in contact with any of the fuel that was in your tank. (Is it at towards the rear of the tank?)
3. The computer that calculates how many miles left does so by using the information on current fuel consumption, gained via the ECU (Electronic Control Unit) and the amount of fuel perceived to be in the tank. If you haven't reset the fuel computer in a long while you MAY end up with an inaccurate reading. Every time you fill up reset it. This can be done by holding the button that cycles the display on the computer in for a few seconds.
Also, it's worth remembering most fuel gauges don't show any reserve fuel that may be in your tank, this is normally around 50km from when the warning light comes on, or you are in the red, depentant on the car make.
Try not to let your tank run too low whenever possible anyways as this is when you risk "dirt" being drawn into your engine.
Hope this helps!

What Do You Need To Know About Paint Thickness Gauge
A paint thickness gauge is an electronic machine to measure the thickness of paint covering a plane. As you may consider in an automotive manufacturing unit this type of calculation is very important and a paint thickness gauge is needed to to check that the paint around the car is of a constant thickness so no patches will develop.
A paint thickness gauge is one type of measuring a covering thickness. A paint thickness gauge is meant more to be used on equipment which are covered in paint or varnish. There are also far more scientific gauges that may measure the thickness of other equipment such as chrome or copper. That is important as it ensures the covering applied to a surface is of excellent quality.
Paint thickness gauges work in several methods and you will need to make use of different types of gauges for different materials. Paint might be applied to wood or metal and the type of paint thickness gauge you'll require for wood is totally different to that compulsory to metal.
If you are testing the paint thickness on a material that isn't metallic, such as wood, you'll need to make use of an ultrasonic paint thickness gauge. An ultrasonic paint thickness gauge can determine the depth of the paint on the wood, with out damaging the paint job or the wood underneath. While you place a probe on the surface of the area you are testing a pulse is transmitted through the layer of paint. This pulse signal is returned to the system and is analyzed. The paint thickness gauge will then return a reading relating to the thickness of the paint masking the wood.
On metallic surfaces a special type of paint thickness gauge is required, corresponding to a magnetic pull-off thickness gauge. By measuring the energy of the magnetic attraction the paint thickness could be determined. Though these paint thickness gauges may be less accurate than other methods they're usually cheaper and for a lot of enterprise purposes they are going to be absolutely fine. So you do not have to buy the most costly paint thickness gauge money can buy.
Relying on the materials you work with at your corporation, there are plenty of different types of paint thickness gauges out there to you. First off determined what stage of accuracy you need to have the job done. It's not essential to get the most superior paint thickness gauge available on the market if it's only going for use for simple readings. A more advanced paint thickness gauge might be totally unnecessary for your requirements and also will be pricey. More expensive units may even require mor calibration to done to maintain them exact.
Most manufacturers of paint thickness gauges will have complete technical particulars accessible for you on their website. Take a look at your budget and the real needs that the paint thickness gauge might be used for and then have a look on the internet to seek out the proper one. Make sure you select the right paint thickness gauge for the material it is going to be used on as there are numerous different types as well as the improper type of paint thickness gauge won't do the right job.
