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.

International Restricted Portable Gauging

Restricted and open portable gauging provide a convenient and accurate means for measuring ullage, product temperature and the oil-water interface.

The units are configured to operate in the trimode, bimode, interface or temperature mode. Each portable gauging is designed to maximize ease of use. A single penetration of each tank can provide comprehensive data about internal tank conditions.

When the electronic probe senses hydrocarbon, a steady tone is heard; when sensing water, it emits an intermittent tone. Temperature is shown on an LED display in the hub of the instrument.

Grounding and Overfill Protection System

We have delivered reliable grounding and overfill monitors that prevent dangerous spills and accidents. From grounding and overfill protection systems and cane probes to rack monitors and heavy-duty plug/cord sets, our products offer reliable, enduring solutions for our client’s greatest challenges.

We offer a full line of grounding and overfill protection systems. Ideal for preventing costly spillage, rack monitors provide automatic warning of product overflow at predetermined levels. Rack monitors provide similar benefits, using a standard thermistor signal format to communicate with thermistor systems on transports or onboard control monitors.

Specially made to offer overfill detection in the absence of sensors within a railcar or tank, probes provide enhanced reliability regardless of variations related to the environment, product, or temperature conditions.

Plug and cord sets provide easy use and handling while offering enhanced corrosion resistance, safety, reliability, and long product-cycle life.

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.

Portable gauging for accurate measurement

Portable gauging for mobile use for the accurate measurement and recording of pressure profiles. There are interchangeable pressure sensors with measuring ranges of up to 8,000 bar available for the instruments.

Through this, portable gauging are particularly suitable as test instruments for a large variety of applications in the widest range of industries.

Data recorded in the portable gauging can be evaluated via PC software. Some instruments document calibrations in the internal memory, which can later be read on a PC.

Portable Density Meters for Your Daily Applications

The portable density meter is designed for petroleum testing applications. This portable tester is commonly used in refineries, fuel terminals, offshore and transportation applications.

The portable density meter is intrinsically safe in hazardous testing environments. All wetted parts and the special housing are resistant to petroleum samples and similar solvents. The leak-proof sealed housing is safe against humidity and spills and makes the unit suitable for harsh industrial and field conditions.

The portable density meter is an officially accepted field method for the new ASTM Standard “D7777-12” which describes the “Test Method for Density, Relative Density, or API Gravity of Liquid Petroleum by portable density meter ” with a minimum accuracy requirement of 0.001g/cm3.

Oil level gauge

The main element of the level gauge is the body. Incorporated into this body are the liquid channel (if necessary the heating channel) and the seating faces for the chambered seals and sight glasses.

Onto the body are mounted, or are already integrated, the valve heads and process connections. Drain or vent are also possible.

Applications of the level gauge:

  • Continuous level indication without power supply.
  • Direct indication of the level.
  • Individual design and corrosion resistant materials make the products suitable for a broad range of applications.
  • Chemical, petrochemical industry, oil and natural gas extraction (on- and offshore), shipbuilding, machine building, power generating equipment, power plants.
  • Oil and gas, heat transfer and refrigeration systems, plants for cryogenics.
