Virtual Gauge

How many times have you been dealing with Level Indicators that are no longer working or working incorrectly? Let's see, as usual, causes and remedies.


The most common problem that arises is the lack of sealing both near the Connector, weak point of this device, and, in rare cases, close to the junction point between the two transparent plastic half-shells, through which it is easy for humidity to enter and the formation of internal condensate, which leads to oxidize the electric sliding contacts.

In the best quality products, these contacts are also protected with golden plating, but with the time and the continuous movements combined with inevitable vibrations, even the hardest plating ends up being consumed, so the contact oxidizes and is compromised to such an extent that even with deoxidizer sprays, it is no longer possible to restore the electrical continuity.


For the external Indicators, mounted on the Multivalves, at a short distance away from the road surface, the problem is even more serious, as they are more exposed also to heavy sprinkles of rainwater, sprayed by the wheels.

Therefore those Hall Effect Indicators have higher reliability, since they are not equipped with a moving Needle for the Level Reading, and so they are much less subject to the oxidation phenomenon, since there are no sliding contacts in continuous motion.
It is true that without the needle the advantage of the direct reading is missed, but in many cases this reading becomes impractical for the position of the Multivalve, which makes it very uncomfortable for observation (under shelves, under screwed covers, below the car, etc...).

For the most exposed Indicators, it would therefore be good to protect the connector area with silicone (that however also loses its effectiveness over time), or rather it would be better using the vaselina to fully fill the Connector Socket, before plugging in the small connector.



Instead, the problems that are often encountered, even when the Level Indicator works correctly, from an electrical point of view, are of a different nature and concern: POOR PRECISION or TOTALLY WRONG INDICATIONS!
Such inconveniences are so boring to the point that most drivers, after a few initial attempts, having realized that the exact amount of Gas in the tank will unfortunately remain almost always a mystery, no longer rely on the information coming from the Level Indicator and prefer to reset the odometer every time, relying to the distance traveled, never precise because one thing is the miles traveled uphill, one thing the miles traveled downhill...

Unreliability comes from several causes:

  1. 1 - type of Gas: LPG or CNG

  2. 2 - incorrect indication of the various quarters of the tank

  3. 3 - use of toroidal tanks

  4. 4 - long climbs or descents

1 - Type of Gas: LPG or CNG

Methane, in contrast to LPG that is in Liquid state, being in the gaseous state, makes the Level Reading much more reliable and precise, based on the pressure measurement of the Gas in the tank, which is not subject to the swings due to Vehicle movement, instead of the floating in LPG Tanks.


It often happens that, for example, the 4 LEDs of the Commutator Switch remain lit for so many miles and then 3 LEDs last for only a few moments, quickly switching to 2 LEDs or directly to Reserve...
The overwhelming majority of the Level Indicators on the market are almost never LINEAR. If you mount an Indicator on a Multivalve and try to move the float manually, you will notice, observing on the Software the Blue Color Bar, that it will move irregularly, which hardly coincide with the Gas Tank Quarters.


To find a better correlation between the LEDs of the Switch and the Tank Quarters, which are indicated by the Needle on the Indicator, just move to the desired location with the mouse pointer, on the Program, the Colored Circles indicating the various quarters of the Gas Tank.
For example, move the float so that it indicates more than 1 QUARTER and move the orange circle of the first quarter a little before the Blue Bar; you will see two lit LEDs.


Note that you cannot be sure that the position indicated by the Mechanical Indicator Needle follows exactly the Tank's geometry, which is a variable (circular) section, and the right position within the Tank. In fact, a more correct set-up would require theoretically to proceed as follows:
- fill a quarter of a Gas Tank
- discontinue gas delivery, releasing the Service Station pistol, which with its pressure would move the float downward
- adjust the relative notch on the Software
- fill in the second quarter
- release the pistol
- and so on... for every quarter...

It's obviously a pretty long wasting of time, as well as almost useless if we talk about LPG, that being Liquid will always be in continuous motion...
On the other hand, the Software allows you to save the work you have done to benefit from Tanks, Multivalves and Indicators of the same type, to be reused in the future.


If you consider that in a vehicle moving, subject to continuous acceleration and braking, the position of the LPG in a Toroidal Tank has about the appearance shown in the following image, with Blue color, you understand that measuring the amount of Gas in these conditions it's a chimera, with the float continuously swinging up and down, from its minimum to maximum position, because a part of the tank is emptied horizontally.


The microprocessors of the Gas Control Units perform a reading average, trying not to be influenced by a continuously unstable position, but the result, however very appreciable, can not always be considered accurate.

Cylindrical Tanks, if mounted orthogonally to the direction of travel, are less prone to swings and have lower floating excursions; consequently, the reading is definitely more accurate than in a Toroidal Tank.



Despite the presence of the Software absorber, in order to mediate the variations, in the case of prolonged stoppage of the Liquid in the same position, such as in the long ascending or descending tracts, the Control Unit is led to errors of assessment from the wrong position of the float, showing also in this case an incorrect Level.




The answer is YES, this indicator exists, it is also inexpensive, and it is:



With the new firware version, 6.04 - May 2017, by which you can upgrade all our Units manufactured 16 years ago to today, models: POWERFUeL, EasySeq, RxPOWERFUeL, PowerEvolution, Evolution, GasEnergyPower, GasEnergy, K2, Next Generation, we have added the possibility of Calculating by the ECU, the amount of Gas Consumed, according to the Opening Times of the Gas Injectors, RPM, Pressure, Temperature, and so on.
The result is a much more precise VIRTUAL LEVEL INDICATOR.


Let's take a look at PRO and CONTRO of the VIRTUAL GAUGE.

The advantages are:

- accuracy in measurement is much higher: one quarter corresponds to a quarter, Reserve is Reserve, and so on.

- the measurement is no longer related to the movement of the Liquid, braking, accelerating, climbing or descending

- you can eliminate completely the use of an Indicator, saving not only the cost of the sensor but also the time for its installation, setup, maintenance

- if you break a Traditional Indicator, you can avoid replacing it by using the Virtual Indicator

- if also the Pressure Sensor is broken, or it is not installed, with the Virtual Indicator it is also possible to perform the self switching over to Petrol when Gas is finished, WITHOUT USING PRESSURE SENSORS, further money savings

- it is possible to measure the Gas Level on all those Gas Tanks that cannot have a Level Indicator such as Tanks for boats, three-wheel vehicles, scooters, etc.

The disadvantages are:

- the need to fill completely the Gas Tank each time, no longer having a sensor to detect the filling state

- for the same reason, when the Gas is over, you lose the advantage of being able to switch back to Gas automatically after a refill.


However, in order to avoid the disadvantages and in order to retain only the advantages of both the Traditional and the Virtual Indicator, a good way is to use the two indicators simultaneously: in this case the Control Unit will use the Traditional Indicator only to establish the Level after a Refill and will use the Virtual Indicator for an accurate measurement.

Let's see how to use the Double (Traditional+Virtual) Indicator:

Set the Real Indicator in the normal way and click on the icon of the Green Gearing to open the Advanced Settings for the Gauge.


Then select "Use ALSO the VIRTUAL GAUGE".
