Compared to Pycnometers and Hydrometers
Manual methods are being replaced by digital density meters for many critical reasons. Even though digital density meters are more expensive, it is a necessary investment.
This comparison datasheet gives a description, applications, and advantages and disadvantages for the following instruments:
Benchtop digital density meter
Handheld digital density meter
Manual methods for density measurements: Manual methods like pycnometers and hydrometers are widely used for the determination of density and related values, e.g. specific gravity, alcohol%, BRIX°, API degrees, Baumé, Plato, etc. Although these methods are easy to use and quite inexpensive, they require expertise in every step of the manual operation protocols, which often affects the accuracy and reliability of the results. Most often, different operators will obtain different results for the same sample.
Digital methods for automatic density measurement: Digital density meters use the oscillation tube technology to measure very accurately the density of a sample in a short time. In addition, benchtop digital density meters use a built-in Peltier thermostat to control the temperature of the sample. The measurement is started by pressing a key, after a short time the result appears on the screen and can be printed, sent to a computer or exported to LIMS.

Tank gauge with density temperature mass measurement have their advantages: They measure rate changes, can be viewed from long distances, and do not require power. But if accuracy is vital when measuring pressure, industrial analog tank gauge with density temperature mass measurement simply cannot compare to how precisely tank gauge with density temperature mass measurement measure pressure. Tank gauge with density temperature mass measurement offer many other advantages as well.
Advantages of tank gauge with density temperature mass measurement
Many applications for tank gauge with density temperature mass measurement require that they be used in temporary installations. Tank gauge with density temperature mass measurement, like the DG-10 digital pressure gauge, are suitable for a wide range of applications and industries, including mechanical engineering, hydraulics/pneumatics, pumps/compressors, and general service/test operations.
Since they may be transported around in the intervening periods during application, tank gauge with density temperature mass measurement feature a stainless steel case, well-designed battery housing, and robust electronics to ensure the longevity of the gauges and subsequent accuracy of readings. An optional rubber cover is available for additional protection for the DG-10.
The readings that tank gauge with density temperature mass measurement offer on digital displays are as fast as they are precise. When a local digital display is required, a digital pressure gauge, like the DG-10, is the ideal solution. They take the manual work out of calculating pressure by reading international measurement units including bar, psi, and MPa. The multi-function display also features a bar graph with a drag pointer and a MIN/MAX memory feature which can recall minimum and maximum pressure readings.

Definition – What does Automatic Tank Gauge mean?
An Automatic Tank Gauge is a device that automatically measures the level of crude oil, LNG and petroleum products in storage tanks and raises an alarm when the level goes down or up the threshold limits. It operates electronically and keeping track of any leakages in the tank. When the upper limit of re-filling the tank is reached, it cuts off the supply from the inlet pipeline and intimates the operator on their human machine interface.
Petropedia explains Automatic Tank Gauge
Automatic tank gauge (ATG) systems measure the levels of liquids inside tanks with the help of electronic probes. These probes consist of long rods that house certain number of sensors known as floats. The position of the floats informs the operator sitting at the ATG console about the amount of petroleum product present in the tank. Apart from measuring the petroleum levels, the probe rod also houses thermistors that measure the liquid temperature.
An ATG console machine is connected electronically with all the storage tanks located inside the main facility and displays all the internal views of a storage tank to the operator sitting at the console.

Improve Terminal Operations with High Performance Bulk Liquid Measurements
Reduce uncertainty in oil inventory and transfers:
• Receive real-time tank data for accurate net volume calculations.
• Get certified custody transfer accuracy.
• Utilize tank capacity efficiently.
• Comply with overfill prevention standards such as API 2350.
• Use SIL 2 and SIL 3 certified devices.
Simplify installation and terminal operations:
• Benefit from unique 2-in-1 technology.
• Simplify automation and expansion with Smart Wireless.
• Use gauge emulation to replace old mechanical gauges.
How the tank gauging system works
The tank gauging system monitors inventory, so you know the exact amount of stored products. The tank gauging system measures precise batches and custody transfers between ship and shore as well as in pipeline transmissions. Use the tank gauging system for everyday operations, oil movement, scheduling purposes and blending programs. Keep accurate track of leaks and prevent overfills to reduce environmental impact and the financial consequences of oil losses.

The servo tank gauge is equipped with a patented Servo Auto Test feature that increases its safety integrity as well as diagnostic coverage, allowing it to be used in overfill protection loops to prevent spillage. The servo tank gauge has a Safe Failure Fraction (SFF) of more than 90% which allows it to be used in SIL-2 safety loops.
If used in a redundant configuration, the servo tank gauge can also be used in SIL-3 rated loops. With these diagnostics, the safety proof-test interval can be extended to 5 years, significantly bringing down the operational cost compared to other solutions that require a proof test to be carried out every year. A highly accurate and advanced force transducer, microprocessor control and advanced software give users precise, reliable measurement and control.
Installation is easy. Almost any nozzle 2” and up can be used, even with the tank being in service. To simplify startup, calibration and servicing, the portable tool can be used to bypass the central system.

When it comes to our customers, we have a pretty good idea how much fuel is in their tank. It’s based on a series of calculations and basic knowledge of your home, all which is outlined on our How does automatic delivery work page. Whether you’re an automatic delivery customer or a will call customer, the oil tank in your home has a gauge on it. We would like to help you know how to read your tank gauge with density temperature mass measurement and how much fuel is in your tank based on where the gauge is.
There are several different types of gauges that are install in tanks, one of the most popular and difficult is a bobber type gauge. This a long glass tube with lines for full, ¾, ½, ¼, and measurements in between. Inside the tube is a bobber that represents where how much oil is in the tank gauge with density temperature mass measurement, similar to the image above. Many of customers will call and state that the tank gauge with density temperature mass measurement is empty when the bottom of the bobber hits E. The bobber is meant to be read from the top down. So if the top of the bobber is at ¼ you have enough oil for several days in the winter, but should schedule a delivery or a delivery will be on it’s way. Other gauges include dials and old time outside thermometer styles which can be easier to read off.
Now what does a ¼ tank mean? Using the image below you’ll know how much fuel is in your tank at any given moment. Now these numbers are based on a standard 275 oil tank. When the tank gauge with density temperature mass measurement is full will only have about 255 gallons in it instead of a full 275. This is because of air inside the tank gauge with density temperature mass measurement that prevents it from being maxed out. When a driver makes a delivery they listen for a whistle that comes from the vent pipe (one of the two pipes that run out of your tank). This whistle means that tank is full.
