Function and System Design of Servo Tank Gauge

Maintenance Prediction

Servo tank gauge will provide advance warning of required maintenance, such as replacement of worn wire, etc. The operating life span of electrical and mechanical parts of the servo tank gauge are factory set within the instruments memory. This information is checked with the built‐ in clock and then compared, and registered in the instrument.

Automatic Displacer Weight Compensation

The displacer can be checked for buildup or corrosion by comparing the measured weight of the displacer in the air with the pre‐ programmed displacer weight.

The servo tank gauge can be set to perform periodical checks for the displacer weight; any deviations in the weight will then be corrected and an alarm or memo initiated.

Automatic Compensation of Wire Length

When the displaceris moved from the level position to the reference point(mechanicalstop within the instrument),the calibration can be checked. If there is any deviation outside the tolerance, the instrument will emit an alarm. If the deviation is within the tolerance (set by the customer), an automatic recalibration will be done. This function can be working manually or automatically in pre‐set time intervals.

What does a density meter measure?

What is Density Meter?

Density ρ is a characteristic property of materials and indicates the relationship of mass m to volume V. It is measured in g/cm³ or kg/m³. For high-precision measurements, the most significant influencing factor is the temperature of the sample. It is essential therefore that modern density meters are equipped with efficient temperature control of the measurement room.

Digital density meter measurement using the oscillating U-tube principle

The example of a tuning fork shows that by applying a mechanical impulse one can generate a sound with a characteristic pitch. This sound is the result of the oscillation created by deflecting the prongs of the tuning fork. A determining factor in the pitch of the note obtained, and thus of the oscillating frequency, is the mass of the tuning fork.

Digital density meter measurement puts this relationship to use by means of the U-tube oscillation principle. The extremely fine capillaries are made to oscillate by a piezoelectric or magnetic transducer with a characteristic frequency.

The resulting resonant frequency of the U-tube will depend on the mass of the filled sample. This frequency can be measured very accurately and used to calculate the density meter of the sample. The physical relationship of oscillation frequency (the reciprocal of the period of oscillation) to density meter is very simple and linear.
Accordingly, calibration is only possible with two standards as a rule – air and water.

Benefits of Installing an Automatic Tank Gauge

An automatic tank gauge is an important electronic device for every gas station. Its basic function is to monitor the fuel level in the tank accurately to make sure that the tank is not leaking. It also indicates what is happening inside the tank such as the fuel level, water level and volume, temperature, and high and low fuel level warnings.

Installing an automatic tank gauge is useful for monitoring your tank at all times and other interstitial spaces in tanks and piping. There will always be an ongoing measurement of tank levels and temperature to ensure the integrity of your product and to help avoid gas leaks. Automatic tank gauge’s are the most cost-effective monetary system to check up on your tank gauge.

Here we’ll list down the benefits of Installing an Automatic Tank Gauge:

Installing an ATG is cost-efficient

Having a device that monitors the maintenance of your gas station prevents accidents from occurring. Having an automatic tank gauge is worth your investment as it ensures a safer place and guarantees protection for everyone in the vicinity. For gasoline station owners and operators, it is an investment worth knowing the everyday performance of their equipment.

An ATG will save you and the workers so much time.

Automatic tank gauge’s are excellent additions to your fleet’s maintenance. It is mostly placed above or below the tank so anyone can easily monitor the fuel or lubricant volume to assess the tank condition without having a hard time. It can also be wired or remotely accessed via a wireless modem.

Gone are the days of inaccurate, hard, and unsafe manual maintenance with automatic tank gauge you will be able to get the most accurate inventory at all times and will help minimize a loss on product contamination or tank leaks.

An ATG ensures the conservation of your equipment.

Another key benefit of installing an automatic tank gauge is the reassurance that you will always have enough gas on hand to meet your inventory needs. Automatic tank gauge systems have an alert function to help you maintain all tanks perfectly. It will automatically tell you when you need to re-order and refill.

One thing that the operators always neglect is the overall maintenance of different equipment while some even ignore leaks and aren’t alarmed by it. Nonetheless, the purpose of having an automatic tank gauge is to know that no leaks will go undetected and problems will be resolved and fixed immediately.

ATGs are continuously improving and evolving.

Now that electronic devices are gradually evolving, the automatic tank gauge also follows. It remains a software solution to help maximize time management for deliveries and inventory transparency. An automatic tank gauge aims to specifically protect your fluid inventory needs and makes you stay at ease to be able to focus your attention on customers and other business needs.

How to Check Your Propane Tank Gauge with LTD Percentage

With more time being spent at home, Blossman Gas is recommending that customers regularly monitor their propane tank level to ensure an adequate level of propane to fuel your furnace or gas appliances. Here’s how.

The frequency at which you’ll need to order propane depends on a number of factors:

  • Number of appliances using propane
  • Total size of your propane tank/s
  • Size of your home

Modern propane tanks are equipped with a tank gauge with LTD that helps you verify the level of propane left in your tank gauge with LTD. To check the tank gauge on your tank, look for a round dial that looks similar to a speedometer. Typically, it is located at the top of your propane tank gauge next to the fill pipe. The numbers on the tank gauge range from 5-95. These numbers indicate the percentage of how much your tank gauge with LTD is filled – NOT the number of gallons left in the tank gauge with LTD.

Good to note: propane tank gauge are designed to be filled to 80% of capacity. This is because gas needs room to expand with changing temperatures. A “full” propane tank gauge with LTD will read 80%.

If your tank gauge with LTD reads 30% or lower, it’s time to request a delivery! This allows enough time to get your request scheduled and delivered without the worry of running out.

Choose right Density Meter for Industrial Application

Density meters are vital measurement instruments used in almost every industrial process. No matter what industrial sector one considers, if material is flowing through a pipeline, it most likely must be measured in some way. Understanding the media in the pipeline is the foundation of process control.

The Different Types of Density Meters

The variability of media type, flow rate, pipe sizes and other factors warrant the existence of several different types of density meter. Below you can find a guideline for the methodology of each. Some of these instruments have been around for decades, whereas some are new and disruptive technologies. Each instrument tends to have it’s “sweet spot” for specific applications depending on the process, environment and budget. This guideline will help to insure that your process is using the most efficient instrumentation available.

The nuclear density meter (or nuclear density gauge) is an energy based instrument known for its flexibility within processing applications. It can endure up to 50 percent solid slurry. Nuclear density meters are not appropriate, however, for processes involving edible materials, mobile processes or high precision applications. It’s most limiting factor is that, like anything else with a nuclear core, it is unstable and constantly emitting radiation. Nuclear density meters have a relatively long life time. However, when the nuclear source means emissions are too weak to provide function it requires proper disposal. The clamp on design of this unit and its operating principles allow it to be installed in a wide array of applications including most standard piping materials as well as either horizontal or vertical piping configurations.

How To Read A Propane Tank Gauge For LPG

If you have a propane tank for home energy usage, then you’ve probably noticed that after a propane delivery, the tank gauge for LPG reads 80%.

Don’t worry, you’re not being scammed and there is nothing wrong with your tank or the gauge. Although you use propane in gas form, propane is stored as a liquid in your tank to allow it space to expand and contract as the ambient temperature rises and falls. The maximum fill percentage is always going to be 80%.

You can perform some simple math to determine how much gas is in your propane tank. Just multiply the tank’s capacity by the reading on the tank gauge for LPG.

For example, if your 500-gallon tank is showing a gauge reading of 60%, that means you have 300 gallons of gas remaining in your tank (500 x 0.6).
