How to Take Measurement with Meters & Gauges?

There is a number of meters and gauges present on a regular car’s dashboard. Minimum, you will see a speedometer and fuel gauge for sure. Some other additional gauges are temperature gauge and oil pressure meter as well as meters like tachometer and voltmeter.

Warning lights are the alternatives for the additional meters.

So, the most frequent question asked by users and drivers is…How to Take Measurement with Meters & Gauges? Or, how to read auto-electrical meter parts?

The modern driver is used to reading the modern dashboard that indicates everything going on in the car.

Compared to classic and old cars, today’s meters and gauges are more advanced. But the classic ones hold their own beauty. The dials present on the dashboard are very important and show the current status of your car.

Well, in this post I am going to review Meters and Gauges.

Read the guide completely and know How to take measurements with meters and gauges.


What are Meters in auto-vehicle?

Meters are a very crucial auto-electrical part of your vehicle. Lights on the dashboards illuminate indicators and tell what you need to check on your car.

These auto-parts are communication tools between the car and the car’s driver.

While driving on the road you have to check the meters to know about the current situation of the car.

On FARGO, we have a wide range of meters as auto-electrical parts in India. Our products are included from well-known OEMs like VETHREE Instruments, KAMEI AUTOELECTRIK, and UNOMINDA.

What are Gauges in auto-vehicle?

Besides auto-meters, gauges are also present on the car’s dashboard representing several other conditions related to your car.

These devices are present in your car that gives certain measurements into of car’s dimensional information. Even a simple gauge can measure and indicate complicated risks on your vehicle.

The modern gauges are used for evaluating pressure and fuel flow.

Having proper functioning gauges is necessary for a vehicle owner. It not only indicates the conditions but also gives warnings in case of any failure.


Types of Meters and Gauges


When it comes to meters and gauges, there are numbers of sorts.

For every specific purpose, there are different meters and gauges present on your vehicle. Each tool is connected to particular work and indicates its condition of it.

Talking about the meters, there is Speedometer, Tachometer, a Voltmeter, and others as well.

And for gauges, are Fuel Gauge, Water Temperature Gauge, and Oil Pressure Gauge.

Besides these…there are several other meters and gauges as well. But these are the basic ones that are defiantly present on your vehicle.

Now, you will read about measuring the different meters and gauges.


Measuring the Meters


Let’s understand how to take measurements of some common meters in vehicles.



The speedometer is one of the most used meters in cars that are driven by a cable that spins in a tube. However, today the electronic version is getting installed in the vehicles for better indications.

It indicates the current speed at which the vehicle is traveling!

With the help of a needle, the speedometers digitally indicate the speed. It reflects the speed of the vehicle from the transmission output shaft speed sensor. The device algorithm covers and displays it properly.

Drivers should always monitor the speedometer for safety.



The tachometer is present on the vehicle’s dashboard measuring and indicating the Revolutions Per Minute of the engine or how fast the engine is rotating. You must know how to read this meter while accelerating the car.

However, the tachometer is one of the least used meters with automatic transmission.

While shifting the engine you have to make sure that it does not cross the red zone, else it will damage the engine. There are some engines protected by the red zone area.

There are marking on the tachometer like 1, 2, 3, and so on.

You may see reading RPMX1000 that tells you to multiply the indicated reading by 1000. For example, if the needle is on 3 then this means the engine has 3,000 RPM.


Measuring the Gauges


Let’s read how to measure some common gauges in a vehicle!


Fuel Gauge

The fuel gauge indicates the level of fuel present on the vehicle. It tells the driver how much fuel is left in the vehicle that will be used for combustion. This gauge is connected to a component in a tank and attached to a rail called float.

The needle of the gauge does not move continuously, instead, it shows the average percentage.

To check the accurate fuel left in the tank…you should see when the vehicle is on a surface without acceleration or deceleration.


Oil Pressure Gauge

The oil pressure gauge is also known as a warning gauge that measures oil pressure present in the engine in pounds per inch.

If the engine has no oil pressure even for a minute…it will directly harm the vehicle’s engine.

So, if the oil pressure gauge is showing diminishing or beeping lights then it means that the oil pressure in your engine is low. In this situation, off the engine as soon as possible.


Water or Temperature Gauge

Like oil pressure gauges…water and temperature gauges also tell a lot about your vehicle’s conditions.

See if the gauge is inactive to move up then you may need a new thermostat. A little bit hotter than regular is okay reading. There may be a sudden burst or leak in the engine which can be treated.

You have to off the engine while taking the vehicle side on the road and wait till it cools down.



So, I hope now you know How to Take Measurements with meters & Gauges.

Meters and gauges are a very essential part of a vehicle as they work as a communication medium between you and your vehicle. So, make sure all the tools on your dashboard are working properly.
