Diesel Fuel Flow Meters Applications

Diesel, bio-diesel, kerosene, gasoline.

Petroleum, organic liquid, inorganic liquid.

Liquefied gas, natural gas, coal gas.

Oil, DEF, heating oil, grease and certain chemicals, low temperature fluid flow measurement.

Fuel flowmeter refers to the flowmeter used to measure the flow rate of fuel. Commonly referred to as turbine flow meters and oval gear flow meters.

A flow meter is used to measure the quantity of fluid that has been moved during the transfer process. They have a visual display, which can be either mechanical or digital, for the user to read off the measurement. Flow meters are used within a variety of fluid transfer applications. And therefore whilst they are always used to measure the fluid, the ways in which they work are slightly different.
Of course, the fuel flow meter also has some characteristics of its own, such as:
Explosion proof
Pulse output
Unaffected by changes in fluid density, viscosity, temperature, pressure, and conductivity.

If you need more accurate measurement, you can choose a mass flow meterCoriolis mass flowmeters have zero drift but the impact is relatively small. Higher operating costs. Mass flow meters can measure temperature and density online. Oval gears are relatively stable for mechanical flow meters.

Turbine Flow Meters are the most widely used diesel fuel flow meters. Measure your diesel fuel or oil consumption with our fuel flow meter.

Diesel Flow Meter Working Principle

The working principle of the turbine flow meter:

Fluid flows through the sensor housing.Because the blade of the impeller has a certain angle with the flow direction, the impulse of the fluid causes the blade to have a rotating moment.

Blades rotate after overcoming frictional torque and fluid resistance.After the torque is balanced, the speed is stable.Under certain conditions, the speed is directly proportional to the flow rate.

Because the blade is magnetically permeable, it is in the magnetic field of a signal detector (made of permanent magnetic steel and coils).

The rotating blade cuts the magnetic field lines and periodically changes the magnetic flux of the coil.

Thereby, an electric pulse signal is induced at both ends of the coil.This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude.

Remotely transmitted to the display instrument, show the instantaneous flow rate and cumulative amount of the fluid.In a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor.

A flow meter is an instrument that indicates the flow rate to be measured and/or the total amount of fluid in a selected time interval. Simply put, it is a meter used to measure the flow of fluid in a pipe or open channel.

Flowmeters are devices that measure the rate of liquid, gas or vapor that passes through them.

Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute).

Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).

Flow measurement can be described by :
Q = A x v

Q is flow rate, A is the crosssectional area of the pipe, and v is the average fluid velocity in the pipe.

Putting this equation into action, the flow of a fluid traveling at an average velocity of a 1 meter per second, through a pipe with a 1 square meter cross-sectional area is 1 cubic meter per second.

Note that Q is a volume per unit time, so Q is commonly denoted as the “volumetric” flow rate.

Now consider the following equation:
W = rho x Q

Where W is flow rate (again – read on), and rho is the fluid density.

Putting this equation into action, the flow rate will be 1 kilogram per second, when 1 cubic meter per second of a fluid with a density of 1 kilogram per cubic meter is flowing.

(The same can be done for the commonly-used “pounds”. Without getting into details — a pound is assumed to be a mass unit.)

Note that W is a mass per unit time, so W is commonly denoted as the “mass” flow rate.

Now — which flow do you want to measure? Not sure? In some applications, measuring the volumetric flow is the thing to do.

Consider filling a tank.

Volumetric flow may be of interest to avoid overflowing a tank, where liquids of differing densities can be added.

(Then again, a level transmitter and high level switch/shutoff may obviate the need for a flowmeter.)

Consider controlling fluid flow into a process that can only accept a limited volume per unit time.

Volumetric flow measurement would seem applicable.

In other processes, mass flow is important.

Consider chemical reactions,where it is desirable to react substances A, B and C.

Of interest is the number of molecules present (its mass), not its volume.

Similarly, when buying and selling products (custody transfer) the mass is important, not its volume.

Flow Meters Pulse Output

The signal output by the flowmeter is generally a pulse signal or a 4-20mA current signal. Both types of signals output instantaneous flow (also used by relays to output cumulative signals. The principle is the same, and will not be repeated).

Our purpose is to PLC Calculate and display the instantaneous flow value and calculate the cumulative value. When the input signal is a pulse signal. When calculating the instantaneous flow rate, you must follow a strict time interval to ensure the accuracy of the instantaneous flow rate.

So, when calculating the instantaneous flow rate, This must be done using timed interrupts. Moreover, only one interrupt program can be run in a PLC system. No other interrupts are allowed (even low priority interrupts are not allowed to run).

Prevents interference with the accuracy of timed intervals. Calculating the instantaneous flow rate is to convert the accumulated pulse number of this time period into the accumulated flow rate. Divided by time is the instantaneous flow.

For the 4-20mA input, the instantaneous flow rate can be directly obtained by simply converting according to its corresponding range. The cumulative flow is the cumulative flow accumulated in each time period is the cumulative flow.

Flow meters with a pulse output essentially use pulses per litre to measure the amount of fluid being dispensed. And then send a signal to an external piece of equipment to tell them this information.

A fuel pulse meter for example is often connected to a remote display or a fuel management system.

Our range of fuel pulse meters include models suitable for different fluids and are compatible with pumps with differing flow rates. Ensure that when selecting your meter, its flow range meets your pump’s flow capabilities.

Of course, in addition to measuring Diesel Fuel flow meters. Other flow meters can also output pulses or 4-20mA signals.

For example, if you need to measure the waste water flow of a 2-inch pipe, then you can refer to: Magnetic Flow Meters Guides.

Fuel Flow Meters for Diesel Engine Fuel Consumption

For generators, boats, trains to hydraulic packs applications. Diesel engines are becoming increasingly popular.

Fuel consumption and efficiency are generally not monitored in Diesel Engines. And the unit’s performance has to be gauged from the manufacturer’s test figures and often never checked again.

With increases in fuel prices, the possibility of theft from remote installations along with many other factors. So the monitoring the fuel consumption of diesel engines has become increasingly important with the transport industries in particular taking a lot more interest in their vehicles fuel consumption.

This chart approximates the fuel consumption of a diesel generator. Based on the size of the generator and the load at which the generator is operating at. Please note that this table is intended to be used as an estimate of how much fuel a generator uses during operation. And is not an exact representation due to various factors that can increase or decrease the amount of fuel consumed.

Fuel flow meter aircraft

A fuel flowmeter for plane indicates an engine’s fuel use in real time. This can be useful to the pilot for ascertaining engine performance and for flight planning calculations.

The types of fuel flow meter used on an aircraft depends primarily on the powerplant being used and the associated fuel system. Not every plane or associated system uses the same kind of flow meter to get the job done.

In most cases, many flow meters perform tasks related to maintaining a single plane. Some of the more common flow meters in use include:

  • Open Channel Flow Meters
  • Mass Flow Meters
  • Turbine Flow Meters
  • Positive Displacement Flow Meters
  • Variable Area Flow Meters
  • Velocity Flow Meters

https://www.aircraftsystemstech.com/2017/06/fuel-system-indicators.html

Every flow meter must be properly maintained and calibrated. All flow meters become inaccurate over time through regular use. Regular re-calibrations and general standards to ensure proper operation.

Flow meters designed for the aviation industry are made of the highest quality materials and to specific industry standards. That way, everyone working in the industry and flying the skies can be in the safest environment possible at all times.

Marine diesel fuel flow meter

  • How much fuel is consumed onboard a ship, is directly related to the performance. The better the performance, the lower the fuel consumption during operation. In this equation, accuracy is not negligible.
  • An offset of 1% in measurement on a vessel operating 200 days a year consuming an average of 100 tons a day equals an offset of 200 tons a year. Depending on the price of HFO or MGO used, this misread has the potential to range up to USD 100,000.
  • The Coriolis Mass Flow Meters used in our Fuel Consumption System has an accuracy better than 0,2% of nominal flow directly measured in mass. Whereas most volumetric flow meters are in the range 0,5% to 2,0%. And they rely on volumetric conversion which depends on the temperature to calculate a mass flow.
  • By installing one or more mass flow meters (depending on engine supply line layout and desired insight) fuel consumption can be monitored closely in real-time.
  • The main principle is to measure the flow of fuel before and after the engine and/or generators. When you compare the consumption data with measurements of actual speed and position (based on speed log and GPS signals). You are able to directly measure the fuel efficiency.
  • If you require more detailed readings, for example, one set of meters per consumer or one set for the ship’s entire consumption. Additional flow meters can be installed.
