The temperature probe is generally a thermocouple or RTD, thermocouple temperature voltage changes, the thermal resistance temperature resistance change, that is good.

Calibration management system application management system software
Test calibration management system is the first self-developed software application management calibration management system, using a number of key technologies for test management highly targeted and high availability. Provides an efficient use of resources can be gas station management software achieved, full sharing of information, data, dynamic control of information management and technology institutions for legal metrology. After investigation, in no specific legal metrology technology institutions and research and development test calibration management system. The calibration management system has access to computer software copyrights. The calibration management system will process the management of personnel, equipment, environmental conditions, methods, traceability and other elements combined fuel management software with organic, dynamic management interface between the various data elements; through the calibration management system will be the baseline measurement, standards, reference materials , equipment, personnel, finance, the amount of transmission services in complex data management and data relationships to sort out, unified data standards, making it clear and accurate data resources. And with other hospital calibration management system to achieve a seamless connection, the establishment of a unified database to achieve the integration of scheduling and management, scientific management and optimization of dynamic control.The trade connection authentication, applicable to most tanks, including the fixed roof tank, floating roof tanks tank level gauge system and tank. A wide range of applications, from light products (such as liquefied petroleum gas, liquefied natural gas and gasoline) to heavy products (such as crude oil 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.

Temperature probe calibration calibration method
Move around the reflector so that the echo reaches a maximum angle of incidence corresponding to the point at this time is that the probes or the K-scale values. gas station management software find R100mm described in accordance with a maximum reflected waves makes it possible to adjust the display range is displayed on the screen of the arc of the second echo select gate way for the double gate, A gate with an echo adjustment intersect, regulating B gate intersects with the second echo, adjust the speed of sound value makes the status line sound path fuel monitoring system is 100, velocity values obtained at this time is the actual velocity values of the material. Temperature probe calibration measurement state maintained above the gate way to the positive or negative, so that the state regulate the probe zero sound path measurement line again to 100, the probe zero value is zero at this time to get the value of the probe. There are many oblique temperature probe calibration method does not completely block the test stick using standard temperature probe calibration, the temperature probe calibration may be performed using the known depth of the hole, in theory, the reference reflecting body is smaller, the higher the accuracy of tank gauging system, but the calibration difficulty is correspondingly increased. When using the calibrated orifice by measuring the depth of the hole and the horizontal position, to calibrate the angle of the slope is calculated, and using the measured values of the depth or horizontal position of the probe velocity and zero calibration.

The accuracy of tank calibration software
The main work of calibration of vertical cylindrical tank calibration
software is to determine the radius of the circle plate. The main method
of current confining gauge method, capacity comparison method, optical
plumb method, optical reference line method and optical triangulation fuel management software
method, each method is closely related with the measurement tool, the
ultimate goal is to determine the radius of the circle plate. With the
improvement of processing mode, new measurement tools of mathematics, we
can expect a new calibration method will emerge.Table correction
dedicated tank calibration software, with large flow meter can be used
as gas stations and tank calibration software most important product - electronic diesel fuel pump,
its reserves, the loss will be directly related to the economic
interests of the gas station, and tank volume table accurate or not they
will determine whether the oil station can be improved inventory
control. Domestic oil tank calibration software station is currently
used mostly for one-time and long-buried put to use, in the course of
running the inevitable deformation, tilt and other phenomena, so that
the tank volume table with the factory when there are some errors.In
turn inventory tank level gauge system
control measurement or lose, no matter what method, the reliability and
accuracy of measuring instruments is very important. New diesel flow
meter, metering field in the tank calibration software reaches a higher
level, can help solve refineries and liquid storage tank on the
efficiency, safety and accuracy than ever, growing demand.

Temperature calibration temperature scale established standard equipment types
Temperature measuring instruments and work with standard electronic diesel fuel pump 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 probe calibration, interpolation different temperature zones of different instruments, but the actual temperature probe calibration for its application temperature range is different, so the different temperature probe calibration zones and measuring instruments type its measurement methods are different. Various automatic tank gauge systems industries and regions thermometer traceable to standard equipment in various industries and regions, the thermometer calibration used in the construction industry can be traced portable fuel transfer pump back to the local metering station and then traced to the Chinese China Institute of Metrology temperature probe calibration, 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 temperature measurement. Temperature and the length, mass, time, current, luminous intensity, amount of substance (mole) and known seven basic physical quantities.

Tank calibration software to use with other software
Intelligent tank calibration software with various flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters used in conjunction with intelligent gas station management software can flow parameters of various liquids, steam, natural gas, gas, etc. in general measurements show a cumulative basis, alarm control, transmitter output, data acquisition and communications. Intelligent fuel management software full range of automatic temperature and pressure compensation operations, compensation arbitrary linear totalizer, totalizer prescribing arbitrarily set instantaneous flow, cumulative flow, temperature, pressure and a variety of parameters display low-cut function, resection 0-5% optional intelligent tank calibration software cumulative flow values can be cleared by panel keys, clear operation can lock brownout protection, cumulative flow values retentive longer than five years, all settings after power failure permanently maintained; intelligent tank calibration software advanced modular structure, with a powerful instrument chip, feature set, system upgrade is very convenient.
