What is Fuel Flow Meter?

A fuel flow meter is a device that measures volumetric fuel consumption, or the amount of gasoline that passes through a fuel line in a given amount of time. Meter readings are supplied as the outcomes of its measurements.

A GPS monitoring and telematics platform calculate the following statistics based on this information:

• Fuel use over a period of time.
• For example, liters per 100 km/miles per gallon is an example of average fuel use.

The gadget can monitor the flow rate of a variety of liquids and bulk materials in addition to fuels. A water meter in an apartment. For example, it is as effective as a flow meter. As a result, a gasoline flow meter shall be referred to as a flow meter.

Principle of operation

A flow meter is a device that uses a ring-type measuring chamber to detect direct volumetric fuel consumption.

The operation of a flow meter is based on measuring the amount of fuel that goes through a measurement chamber. The chamber is the most important factor in a flow meter’s accuracy and longevity. The following is how it all comes together:

• The ring forces the fluid from inside and outside the chamber to exit via the output nozzle.
• One rotation of the ring expels a volume of fluid equal to the chamber’s volume. The flow meter’s electronic board generates one output impulse at the same time. As a result, an electrical impulse is created when gasoline goes through a flow meter.

It is generally mentioned in the manufacturer’s instructions how many impulses are necessary for 1 L / 0.26 US GAL of gasoline to flow through the device. Because one impulse corresponds to fuel consumption (which is equal to the volume of the measuring chamber), you only need to compute the difference between the chamber volume and one liter of fuel.

For instance, 1 L translates to 200 pulses on a Technoton DFM 100D flow meter. As a result, the flow meter’s measuring chamber capacity will be 5 ml (1/200 L). This data is subsequently uploaded into a telematics platform as a coefficient for the measuring sensor (see the section “Sensors and Buttons”). The impulses are translated into liters using this coefficient. The telematics platform will process the received data, “decompose” the used fuel data and provide it to users in table format.

Application

Flow meters are used to monitor the amount of gasoline used in the fuel lines of various vehicles and stationary installations. The following items are included in the applicability area:

Vehicles

This can be done via train, plane, or sea.

Additional car accessories

A compressor unit or other equipment affixed to the chassis of a vehicle, for example.

Installations that are stationary

Flow meters can be fitted inside small corporate gas stations tanks.

Fuel changes in the tank have no effect on flow meter readings. As a result, you may fully utilize the gadget when running under the following conditions:

When traveling on difficult terrain, there are constant gasoline variations in the tank.

A flow meter can be used on agricultural machinery (tractors, harvesters, and so on), off-road vehicles, and water transportation, for example.

Long-term inclinations of the fuel tank.

This frequently occurs when a car is parked on a steep incline or drop. Such inclinations are common in street maintenance equipment such as rotary hoes, asphalt milling machines, and other forms of street maintenance equipment.

Fuel fluctuations + long-term tendencies

For example, when working with mining trucks at a quarry.

Because the shape of a gasoline tank typically prevents the installation of several Fuel Level Sensors, employing a single sensor will result in a greater mistake rate. In this instance, we propose using flow meters to provide a more exact reading on the amount of gasoline used.

Fluids of operation

A flow meter can measure any liquid with a kinematic viscosity ranging from 1.5 to 6 mm2/s.

All of the components in a flow meter’s measuring chamber must be lubricated to maintain high measurement precision and reliable operation. Why is diesel used? This is owing to diesel’s lubricating characteristics, which aid in the reduction of friction between surfaces. In most circumstances, the mechanism operates “dry” when it comes to gasoline (except for two-stroke engines having gasoline mixed with engine oil). This “dry” operation hastens to wear, lowers measurement accuracy, and introduces an extra error into the flow meter. As a result, a flow meter can only be used to measure diesel fuel use.
