The oil tank level measurement is characterized in which

The magnetostrictive liquid level meter, measuring tank, which is characterized in:
1 strong reliability: the magnetostrictive gas fuel pump level meter adopts the principle of waveguide, no mechanical 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 suitable for the measurement of chemical raw materials and flammable liquid. No need to open the tank 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 tank top for pipe installation, especially suitable for underground storage tank 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 gas nozzles 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.

Temperature calibration temperature scale established standard equipment types

Temperature measuring instruments and work with standard temperature test, generally a standard method of comparing standard thermometer was seized by the thermometer, that comparison done. Due to the large temperature range specified temperature scale, interpolation different temperature zones of different instruments, but the actual temperature measuring instruments for its application temperature range is different, so the different temperature zones and measuring instruments type its measurement 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 temperature 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 gasoline meter measurement. Temperature and the length, mass, time, 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 temperature of the triple point of water, 1 / 273.16. As the previous definition of the temperature scale used and 273.15K (freezing) to 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.

Some features of the equipment onboard the tanker introduction

To be driven by the engine gearbox,drive installed on the gearbox oil pump, fuel pump to generate power, the liquid inside the tank through a pipe into the pump or pump out. Typically onboard two fuel trucks sodium bicarbonate powder fire extinguisher, tank level gauge system sodium bicarbonate powder fire extinguisher suitable for early fire of flammable and combustible liquids, gases and charged equipment. Breathing valve is fixed at the top of the tank ventilation to ensure the normal state of the tank pressure to prevent overpressure or vacuum station management system so that the tank sustained damage, but also can reduce the tank liquid evaporation loss. Car fire cover is usually a vortex valve structure, without the aid of any tools, with a four-bar mechanism and automobile exhaust pipe tail pipe connected directly without switches or connections fixing screws, Fuel management systems simple and quick to complete the installation and removal of a few seconds. Ignition of flammable materials in a lower concentration of larger establishments, able to completely extinguish car exhaust pipe exhaust entrainment spark. Come on board anti-static facilities are divided into static and static grounding wire line two kinds.
