The key factor in measuring the tank gauging system

Tank gauging system and work with standard system test, generally a standard method of comparing standard thermometer was seized by the thermometer, that comparison done. Due to the large fuel management software range specified system scale, interpolation different system zones of different instruments, but the actual tank gauging system for its application system range is different, so the different system zones and measuring instruments type its tank gauging system methods are different. Various industries and regions thermometer traceable to standard equipment in various industries and regions, the thermometer calibration used in the construction industry can be traced back to the local metering station and then traced to the Chinese China Institute of Metrology fuel management software reference, can also be traced to China Building Science School building energy and environment Test Center, and then finally traced to the China Science and Chinese Academy of reference system measurement. Temperature and the length, mass, time, tank gauging system current, luminous intensity, amount of substance (mole) and known seven basic physical quantities. Thermodynamic temperature (symbol T) is the basic physical hand, its unit is Kelvin (Kelvin symbol K), defined as the thermodynamic tank level gauge system of the triple point of water, 1 / 273.16. As the previous definition of the temperature scale used and 273.15K (freezing) to tank gauging system represent the difference between the temperature, so that each method remains. By definition, equal to the size of degrees Kelvin, the temperature difference can also use Celsius or Kelvin to represent.

Accurate measurement of automatic tank gauge systems of

Management agencies are increasingly hold such a view: the federal guidelines in CFR 280.44 "leak detector in test runs must be based on the manufacturer's requirements" (a) some of the provisions is to require the electronic line leak detectors were site functional Fuel management systems testing. In general, manufacturers hold different views. For example, Veeder - Root automatic tank gauge systems to perform the necessary functional tests as part of every 3.0 gallons / hour testing and accurate testing. Moreover, Veeder - Root insisted that the completion of 3 gallons / hour testing and automatic tank gauge systems tests can be intrinsic to meet EPA requirements for functional testing. Some national and state requirements for electronic line leak detectors for quantitative testing. In tests, to parts for pumps simulate 3.0 gallons scene / hour leak, or even 0.2 gallons / hour and 0.1 gallons / hour leak, and to automatic tank gauge systems confirm the situation stopped probing and requirements. These on-site program generated a lot of need for the industry to solve the problem: test program: Run the electronic system with different manufacturers and models and different. The test will not always be at the pump starts, which is reflected in the presence of mechanical leak detector. Testing conducted on mechanical leak detector may not be fully used in the electronic system testing. Leak detectors, each model petrol dispenser pump will require a unique test procedure. Coordination: a large number of automatic tank gauge systems specified by the customer or a third party remote monitoring. According to instructions, quantitative tests will trigger an alarm, triggering response monitoring center. Therefore requested the parties to coordinate remote monitoring. Alert close the file needs to reflect the inspection process.

Oil tank monitoring system reflects the superiority

The oil tank monitoring system is characterized in which

The magnetostrictive liquid level meter, measuring oil tank monitoring system, which is characterized in:

1 strong reliability: the magnetostrictive liquid level meter adopts the principle of waveguide, no fuel card management services moving parts, so there is no friction, no wear. The converter is enclosed in a stainless steel tube, and measuring the medium non-contact sensor, reliable work, long service life.

2 high precision: the magnetostrictive liquid level gauge with waveguide pulse, work by measuring the initial pulse and the termination of the pulse time to determine the displacement measured, so the measurement precision is high, the resolution is better than 0.01%FS, it is difficult to achieve with other sensor accuracy.

3 safety: explosion-proof performance magnetostrictive liquid level meter high, explosion-proof, safe to use, especially manual fuel transfer pump suitable for the measurement of chemical raw materials and flammable liquid. No need to open the oil tank monitoring system cover measurements, avoid unsafe the existence of manual measurement.

4 magnetostrictive liquid level meter and easy installation and maintenance is simple: the magnetostrictive liquid level meter by the oil tank monitoring system top for pipe installation, electronic diesel fuel pump especially suitable for underground storage oil tank monitoring system installation and operation, and can be used in the installation process does not affect the normal production.

5 convenient for system automation work: two meter magnetostrictive liquid level meter with standard output signal, which is used to process the signals, easy to realize interconnection work, improve the degree of automation of the whole measurement system.

Tank gauging system for range

Diesel flow meter is large reserves of static liquid product in the tank to measure the generic term. It can be used to measure the stock, namely the determination of the tank level controller total amount of product in the tank can also be used to turn the output measure, that is, as product marketing and tax basis. The main two methods: measurement based on volume and quality. Tank gauging system based on volume, the stock of measurement achieved by measuring the liquid level and temperature. In the tank gauging system based on quality, the stock is measured using a liquid measuring hydrostatic liquid column made. In turn inventory control measurement or lose, no fuel monitoring system matter what method, the reliability and accuracy of measuring instruments is very important.Additional requirements for tank gauging systems: Online diagnostics can be used to turn the tank level gauge system output metering, can be seamlessly integrated with the host system and the existing , scalable, service and spare parts, satisfactory price, supplier quality control procedures.

The key factor in the stock tank gauging system measured

Accuracy of measurement is a key factor in the stock of measurement, but the accuracy is only one aspect, tank gauging system, tank gauging instrumentation to consider the general requirements: security, fuel monitoring system accuracy and repeatability, reliability and effectiveness of the operation of compatibility , friendly and easy to operate, independent operation capability, easy maintenance, scalability. Additional requirements for tank gauging systems: Online diagnostics can be used to turn the output metering, tank level gauge system can be seamlessly integrated with the host system and the existing DCS, scalable, service and spare parts, satisfactory price, supplier quality control procedures. A wide range of station management system applications, from light products (such as liquefied petroleum gas, liquefied natural gas and gasoline) to heavy products (such as crude tank gauging system and Li Qing) can be applied. Radar level condensate from the low design concept based on, in the global application, and successfully installed for measuring from gas to liquid products of various heavy crude oil and bitumen.
