Cambodia News (Takeo Province): On July 22, 2021, in Samrong commune/district in Takeo province, the authorities of the CCF department found 3 out of 6 petrol stations were scamming the customers by reducing the quantity of the gasoline.

Very easily done until its tested by weights and measures has we see in the lower photo, but with volatile substances this will fluctuate to some degree naturally on a daily basis with no known tampering.

its the volume of fuel that fluctuates not its weight with temperature changes..... that's why racing cars such as F1 for example measure their fuel load in KG's not litres..... so maybe we start asking for 1KG gas ?

Those Tela stations are just money laundering scams. This is probably instigated by the staff.


Allegedly.

With the temperatures here being pretty stable all your round I don't think the temperature is a real factor in the fuel volume, especially given the amount measured (5 liters?) in the pictures.

The odds the guy running the show changed the parameters of the machine are a lot higher.

Have you guys ever seen the calibration preformed on a forecourt fuel dispenser? This is typical Gilbarco Pump/Dispenser, one product of many types I have worked on over a period of 30 years. Total Cambodia use Gilbarco to calibrate there pumps here.

C&C MODE
In the C&C Mode, the user has the ability to configure variables such that by changing them, they could impact the
results of a given transaction. The C&C mode is accessed by the user, to calibrate the meter, prior to using the
EMR for customer transactions. With a C&C mode switch in place, a mechanical interlock or seal is typically
added by a weights and measures inspector during calibration of the EMR. Once the seal is in place, access to
the C&C parameters is not possible. To access the C&C Mode again, the weights and measures seal must be
removed.
The same is true for the OBC commands that are related to C&C parameters in that commands are available when
the EMR is not in the C&C mode but are available in the Delivery Mode.
The C&C Mode setups must be performed before you make selections in the non-metrological controlled Setup
Mode - There is one exception: When initially powering up an EMR4 System with two Display Heads, System
Address Setup (in Setup Mode) must be completed before entering C&C Mode (see page 27 to page 29).
Entering the C&C Mode requires that a seal-protected wire jumper or switch in the Display Head be changed.
Changes in this mode must be accordance with local W&M authority requirements. In the C&C Mode you:
• Enter the meter input type and calibrate the meter
• Enter product descriptions
• Enter calibration and temperature compensation parameters
• Configure system I/O devices
• Enter the OEM message
• Select between coefficient of expansion or density as a method of temperature compensation for product
delivery
• Enable price changing in the delivery state (if allowed)
• Enable system security code to limit unauthorized access to delivery setups
• Select and modify display formats, operating labels, and print labels
• Enable modifying of the Tank Load volume
• Perform a reboot with or without resetting setup parameters to their factory default positions
In the C&C Mode, the user has the ability to install software updates from an update flash drive

This no surprise both quality and quantity are extremely suspect here. PP petrol does seem better quality and my motorbike runs better on it.

The owner doesn't change the parameters by himself, he pays the the guys doing the initial calibration to do it for him. It's actually common practice. In my town, the only one delivering 100/100 of a liter is the PTT station. The rest deliver 95 /100 or less.
