Servo Tank Gauge Configuration

A servo tank gauge is a device used to measure the level of liquid in a tank. The configuration of a servo tank gauge can vary depending on the specific model and manufacturer, but here are some general steps to configure a servo tank gauge:

Determine the type of tank: The first step is to determine the type of tank that the servo tank gauge will be installed in. The most common types of tanks are cylindrical, rectangular, and spherical. The dimensions and shape of the tank will affect the configuration of the servo tank gauge.

Install the gauge probe: The gauge probe is the part of the servo tank gauge that is inserted into the tank to measure the liquid level. The probe should be installed in a location that will provide an accurate measurement of the liquid level. The probe should be inserted into the tank through a hole that is drilled into the tank.

Install the gauge head: The gauge head is the part of the servo tank gauge that displays the liquid level. The gauge head should be installed in a location that is easily visible and accessible to the user. The gauge head is typically mounted on a bracket or stand that is attached to the tank.

Connect the gauge probe to the gauge head: The gauge probe and gauge head are connected using a cable. The cable should be connected to the probe and head according to the manufacturer’s instructions.

Configure the servo tank gauge: The servo tank gauge will need to be configured to provide accurate readings of the liquid level. The configuration process will vary depending on the specific model and manufacturer of the servo tank gauge. Typically, the gauge will need to be calibrated to the specific tank it is installed in. This involves setting the parameters for the tank dimensions and the liquid being measured.

Test the servo tank gauge: Once the servo tank gauge is installed and configured, it should be tested to ensure that it is providing accurate readings. The tank should be filled with liquid to a known level, and the servo tank gauge should be checked to see if it is reading the correct level.

It’s important to follow the manufacturer’s instructions for installing and configuring a servo tank gauge to ensure accurate measurements of the liquid level in the tank.

How does a tank gauging system work?

A tank gauging system is a method used to measure and monitor the level of liquid in storage tanks, such as those used in the oil and gas industry. There are different types of tank gauging systems available, but the most common method used is through the use of sensors.

The basic operation of a tank gauging system involves measuring the level of the liquid in the tank and converting it to a volume measurement. This is achieved using various types of sensors such as ultrasonic, radar, or capacitance sensors, which are installed on the tank’s surface or inside it.

When the liquid level changes, the sensors detect the change and send a signal to the tank gauging system’s control unit. The control unit then calculates the volume of the liquid based on the level measurement and the tank’s dimensions, taking into account factors such as temperature and pressure.

The tank gauging system also includes a display unit that provides real-time readings of the liquid level, volume, and other relevant data. This allows operators to monitor the tank’s contents and make informed decisions about refilling or emptying the tank.

Vertical accuracy test facility for servo tank gauge instruments

A vertical accuracy test facility for servo tank gauge instruments is a specialized testing apparatus used to calibrate and test the accuracy of servo tank gauge instruments that are used to measure the level of liquids in large storage tanks.

The facility typically consists of a tall, vertical tower that is filled with a liquid of a known density, such as water or oil. The servo tank gauge instrument is then lowered into the tower to measure the level of the liquid at various depths.

The accuracy of the instrument can be determined by comparing the readings it provides to the actual level of the liquid in the tower, which is known based on the density of the liquid and the depth of the instrument.

The facility may also include various instruments and devices to measure the temperature, pressure, and other variables that can affect the accuracy of the servo tank gauge instrument.

Vertical accuracy test facilities for servo tank gauge instruments are important for ensuring the accuracy and reliability of these instruments, which are commonly used in the petroleum and chemical industries to monitor the level of liquids in large storage tanks. Regular calibration and testing can help to ensure that these instruments are providing accurate and consistent measurements, which is crucial for maintaining safe and efficient operations.

Portable Gauging Station for Oil-Water

A portable gauging station for oil-water is a device that is used to measure the amount of oil and water present in a given sample. This is an important tool for companies and organizations that work with oil, such as oil refineries, shipping companies, and oil spill response teams.

The gauging station typically consists of a sampling device, a separation chamber, and measurement instruments. The sampling device is used to collect a sample of the mixture of oil and water, and the separation chamber is used to separate the oil and water into two distinct layers. The measurement instruments are used to determine the volume of each layer and the proportion of oil and water in the sample.

Portable gauging stations are designed to be lightweight and easy to transport, making them ideal for use in remote locations or in emergency situations. They can be battery-operated or powered by a generator, and some models can be operated using solar power.

The accuracy and reliability of the gauging station depend on the quality of the measurement instruments and the separation process. Some gauging stations use advanced technologies such as ultrasonic sensors, optical sensors, or nuclear magnetic resonance (NMR) spectroscopy to achieve high levels of accuracy and precision.

Different Types of Tank Gauging System

Tank gauging systems are used to measure and monitor the level of liquids or gases in tanks, vessels, or silos. There are several types of tank gauging systems available, each with its own advantages and limitations. Here are some of the most common types of tank gauging systems:

Float and Tape Tank Gauging System: This is one of the oldest and simplest types of tank gauging systems. A weighted tape is suspended from a float that floats on the surface of the liquid in the tank. The tape is marked with graduations that indicate the level of liquid in the tank. This system is easy to install and maintain, but it requires manual reading of the tape, which can be time-consuming.

Servo Tank Gauging System: This system uses a servo motor to drive a measuring probe that is immersed in the liquid in the tank. The motor measures the level of the liquid by sensing the torque required to rotate the probe. The servo tank gauging system is accurate and provides real-time measurements, but it is more complex and expensive than other systems.

Radar Tank Gauging System: This system uses radar technology to measure the level of the liquid in the tank. A radar signal is transmitted from a sensor at the top of the tank, and the time taken for the signal to reflect back from the liquid surface is measured. This system is accurate and provides continuous measurement, but it is expensive and requires regular maintenance.

Hydrostatic Tank Gauging System: This system measures the pressure at the bottom of the tank to determine the level of the liquid. The pressure measurement is converted into a level measurement using a formula that takes into account the density of the liquid. This system is accurate and reliable, but it requires calibration for different liquids and operating conditions.

Optical Tank Gauging System: This system uses optical sensors to measure the level of the liquid in the tank. The sensors detect the amount of light that is reflected back from the liquid surface, and this measurement is used to determine the level of the liquid. This system is suitable for clean liquids and provides continuous measurement, but it is sensitive to changes in the optical properties of the liquid.

Digital Portable Density Meter

A digital portable density meter is a handheld instrument used to measure the density of liquids and gases. It is commonly used in industries such as food and beverage, pharmaceuticals, and chemical manufacturing to ensure product quality and consistency.

The density meter works by measuring the buoyancy force on a submerged object, such as a small sphere, and then calculating the density of the fluid based on the mass and volume of the sphere. This method is known as the oscillating U-tube principle.

Digital portable density meters typically have a range of measurement capabilities, from low-density liquids such as oils and alcohols, to high-density liquids such as acids and detergents. They may also be able to measure the density of gases, although this may require additional equipment and calibration.

In addition to density measurement, some digital portable density meters may also have additional features such as temperature measurement and automatic calculation of other parameters such as specific gravity and concentration.

The portability of the density meter allows for on-site measurements and the ability to quickly verify the density of a sample, without having to transport the sample to a laboratory. This can save time and reduce the risk of contamination or sample degradation.

Float Type Servo Tank Gauge

A propane float servo tank gauge consists of moving parts located both inside the tank and outside. At the end of the stem is the float that rises and falls with the level of the propane in the tank.

The float servo tank gauge only provides an approximate tank percentage and cannot be considered 100% reliable. The fixed liquid level gauge is utilized for filling. Tanks with float servo tank gauges measure the volume of the tank as a percentage of the total capacity of the container.

As mentioned above, the float servo tank gauge is not a fully reliable instrument for measuring tank volume. Float servo tank gauges have numerous moving parts that are subject to wear and tear and can also become ineffective in any part of the assembly. If the servo tank gauge needs replacement, the propane tank must be empty.

Overview of Tank Gauging System Technologies

Servo tank gauging system operate on the principle of displacement measurement. A small displacer on a measuring wire is unwound from a drum and accurately positioned in the liquid medium using a servo motor. The weight of the displacer is precisely balanced against a magnetic coupling and the wire drum. When the displacer is lowered and touches the liquid, the weight of the displacer is reduced because of the buoyant force of the liquid.

As a result, the torque in the magnetic coupling is changed and this change is measured by 5 sets of Hall sensors. The signal, an indication of the position of the displacer, is sent to the motor control circuit. As the liquid level rises and falls, the position of the displacer is automatically adjusted by the drive motor. This system provides an outstanding accuracy of +/- 0.7 mm. Servo tank gauging system are ideally suited for light and middle distillates of petroleum.
