Benefits of Tank Gauge System

Fuel is an asset. Protecting this asset and using it wisely is crucial to a profitable operation. That’s where a fuel tank gauge system can pay big dividends, as they work to do more than just measure the level of fuel left in storage tanks but also save money and increase efficiency in a variety of ways.

With sensors and other data-tracking components incorporated into the fuel framework, owners and operators stay aware of everything from fuel levels to temperature, pressure, and other key details.

Below we’ll take a closer look at the importance of fuel tank monitoring and some of the biggest advantages.

Characteristics Of The Best Fuel Tank Gauge Systems

Fuel is a resource, and protecting that resource ensures you’re able to maximize it along with your day-to-day operations. Fuel tank monitoring is also important for staying in compliance with certain environmental regulations.

Increase operational efficiency with rapid response

Fuel tank gauge systems can manage all aspects of fuel, from its procurement, to usage, its condition and even its eventual sale.

Essentially, fuel tank gauge systems allow owners and operators to increase their operational efficiency by real time tracking of key metrics involved in important decisions. And with remote sensors, owners and operators can even monitor and make adjustments remotely.

If an issue is detected, you are immediately alerted so adjustments or repairs can begin sooner and based on what is happening now, not data from days or weeks ago. This not only protects your investment and minimizes lost fuel and downtime.

Environmental compliance

Fuel tanks require routine maintenance. As they age, factors such as rust or algae growth not only impact the quality of the fuel, but can also have environmental impacts. In the event a fuel tank is damaged, there is the potential for fuel to escape, possibly contaminating soil and or groundwater in the area.

One of the big advantages of a fuel tank gauge system is the speed at which issues are detected allowing for faster repairs and minimizing the environmental impact.

How Does a Magnetic Level Gauge Work?

Magnetic level gauges use magnetism to link the indicator in a gauge to a float inside of a vessel in order to accurately show the level of fluid within. As the position of the float changes, the indicator moves up or down by the same amount, meaning that the level in the measuring chamber will always be the same as the fluid level in the vessel itself.

Operating on the principle of conductivity, magnetic level gauges consists of 3 main components: the chamber, the float, and the indicator. The chamber is the main component and can be constructed of any non-magnetic material. It is typically mounted to the side of the vessel, with the liquid level in the chamber set up to match the liquid level in the vessel. While similar to a traditional sight glass in this way, magnetic level gauges can handle some of the more extreme applications, such as ones with highly corrosive or hazardous materials.

To actually get a reading, the ancillary chamber of the magnetic level gauge uses a float that contains a set of permanent magnets. This float is normally constructed of 316 stainless steel or titanium, but can be produced using other materials where needed. When the fluid fluctuates in the primary chamber, it results in a proportionate change in the magnetic level gauge. At LJ Star, each float is custom engineered to meet our customer’s specific application. The float is designed to project a magnetic field through the gauge’s chamber to an externally mounted indicator system in order to easily view internal fluid levels. The external indicator is normally comprised of rotating flags that are brightly colored in order to easily identify when the flag is flipped. Each flag is assembled around rare earth magnetic assemblies that ensure a latching action to eliminate false indication due to vibration.

WATER TANK LEVEL GAUGES

Water tank level gauges are used to quickly tell how much water is in your storage tank at any given time.

Electronic Indicators

Water tank level gauges with electronic indicators are a convenient way to keep an eye on your water levels from inside your own home or office.

Electronic level gauges consist of a transmitter and a receiver. The electronic indicator inside the tank transmits a wireless signal to a receiver located in the home or office.

Level gauges with electronic indicators eliminate the need for you to go to the actual physical location of the tank to read the water level.

Mechanical Indicators

Water tank level gauges with mechanical indicators work by using a weighted float and an indicator. The indicator is connected to a counter-weight which moves down with the rising water level and lifts up the float.

Level gauges with mechanical indicators are precisely accurate, as the sliding indicator located on the outside of the tank is able to match with the water level exactly.

Unlike level gauges with electronic indicators, those with mechanical indicators will never go down on you. Since there are no electronic parts,no power source is required and certainly no batteries. That makes these gauges an appealing option over those with electronic indicators.

Simple Digital Water Flow Meter Circuit using

Simple Digital Water Flow Meter Circuit using
We will be taking a look at water flow sensor, its construction and working and how to interface with Arduino to extract some useful readings.

The proposed project can measure the rate of water flow in litre / minute and total water flow in litres.

Let’s take a look at this water flow sensor.

It is a Hall Effect based water sensor. It has three terminals 5V (nominal working voltage), GND and output. The +5V is red coloured wire, the black one is GND and yellow one is output.

The sensor gives out frequency directly proportional to water flow. The sensor can measure from 1 litre / minute to 30 litre / minute. The water pressure should be less than or equal to 1.75 MPa.

The water can be injected from one end and water flows through the other end.

The sensor may be placed after the main gate-valve of tank; if you want to measure the water flow in a network of water pipes or you can place just before a water tap to measure the water flow of single tap.

The placement of the sensor can be anywhere according to user’s need but, care must be taken to avoid leakage of water.

The sensor has a magnet and Hall Effect sensor; if we take a look at the sides of the water flow sensor, we can witness a plastic turbine in the path of water flow.

A round shaped magnet is embedded at the center of the turbine and the Hall Effect sensor is sealed and protected from moisture and placed above the magnet. The Hall Effect sensor produces a pulse for every revolution of the turbine.

Water Flow Waveform on Serial Plotter
We can see the pulses generated by water flow sensor on serial plotter.

We have blown air through the sensor to rotate the turbine as a test and the waveform generated is shown above. The denser waveform on left hand side represents higher frequency and faster rotation of turbine, the less dense waveform at right hand side signifies the vice versa.

A consistent water flow gives out consistent frequency output.

We have to convert the frequency into litre/minute scale. To do this, the manufacturer has given a formula:

Water flow rate (litre/min) = frequency / 7.5
So, we need to measure the generated frequency and apply the above formula in the program code.

Mass or Volumetric Flow Rate

So you want to measure flow? The answer would seem to be to purchase a flowmeter. With fluid flow defined as the amount of fluid that travels past a given location, this would seem to be straightforward — any flowmeter would suffice. However, consider the The following equation describing the flow of a fluid in a pipe.

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. Similar, when buying and selling products ( custody transfer) the mass is important, not its volume.
How much maintenance does a flowmeter require?
A number of factors influence maintenance requirements and the life expectancy of flowmeters. The major factor, of course, is matching the right instrument to the particular application. Poorly selected devices invariably will cause problems at an early date. Flowmeters with no moving parts usually will require less attention than units with moving parts. But all flowmeters eventually require some kind of maintenance.

Flow meters of Fluid and flow characteristics

The fluid and its given and its pressure, temperature, allowable pressure drop, density (or specific gravity), conductivity, viscosity (Newtonian or not?) and vapor pressure at maximum operating temperature are listed, together with an indication of how these properties might vary or interact. In addition, all safety or toxicity information should be provided, together with detailed data on the fluid’s composition, presence of bubbles, solids (abrasive or soft, size of particles, fibers), tendency to coat, and light transmission qualities (opaque, translucent or transparent?).
Pressure & Temperature Ranges
Expected minimum and maximum pressure and temperature values should be given in addition to the normal operating values when selecting flowmeters. Whether flow can reverse, whether it does not always fill the pipe, whether slug flow can develop (air-solids-liquid), whether aeration or pulsation is likely, whether sudden temperature changes can occur, or whether special precautions are needed during cleaning and maintenance, these facts, too, should be stated.

Piping and Installation Area
Concerning the piping and the area where the flowmeters are to be located, consider: For the piping, its direction (avoid downward flow in liquid applications), size, material, schedule, flange-pressure rating, accessibility, up or downstream turns, valves, regulators, and available straight-pipe run lengths. The specifying engineer must know if vibration or magnetic fields are present or possible in the area, if electric or pneumatic power is available, if the area is classified for explosion hazards, or if there are other special requirements such as compliance with sanitary or clean-in-place (CIP) regulations.

First Steps to Choose the Right Flow Meter

The first step in flow sensor selection is to determine if the flowrate information should be continuous or totalized, and whether this information is needed locally or remotely. If remotely, should the transmission be analog, digital, or shared? And, if shared, what is the required (minimum) data-update frequency? Once these questions are answered, an evaluation of the properties and flow characteristics of the process fluid, and of the piping that will accommodate the flowmeter, should take place.
