These systems for the production test, military and aerospace, storage tank calibration methods , machine monitoring, automation and industrial testing applications to provide services.

Universal test system bus and calibration management system

As a universal test system bus, fuel dispensing pump , PXI (PCI eXtensions for Instrumentation, instrumentation systems for PCI expansion) from the NI (National Instruments) company to complete the development in 1997 and officially launched in 1998, it is committed to replace the traditional VXI bus and GPIB, a new generation of bus standards. Develop PXI specification is intended to be price-performance advantages and PCI bus for the field of instrumentation necessary to extend the desktop PC perfectly combine to form a mainstream virtual instrument test platform. This makes it a high-performance, storage tank calibration methods , low-cost delivery platforms measurement and automation systems.

Temperature sensor calibration (static,dynamic) steps and methods

Calibration of temperature sensors and calibration, like most other sensors, the sensor is placed in a precise measurement, the known temperature of the environment for some time,calibration management system and then check the sensor output records are consistent with the known ambient temperature, and calculate the error sensor.

Natural environment temperature is always a slowly varying quantities, so under normal circumstances to test the temperature of the sensor is a static, which can meet the actual needs of the vast majority of the temperature sensor. Dynamic test rarely,storage tank calibration methods to achieve dynamic temperature detection device is also minimal.

Because the methods and principles of static temperature sensor test is extremely simple, but rare or standards such information.Improve the temperature sensor is the best way to choose the dynamic characteristics of temperature sensitive materials and reduce the quality of the sensor temperature sensing part, fuel dispenser reducing its thermal inertia.

Research and development of calibration management system for mass production of battery management system

Because of the pressure of energy and environmental protection, the development of electric vehicles has become an inevitable trend of the development of automobile industry, and recently in the country a series of policies to promote the electric vehicle industry, the process of urbanization in China is speeding up, which led to the battery management system is one of the key technologies of electric vehicles (BMS) industry. calibration management system  In order to make the BMS the basic detection function can reflect the operation of electric vehicles, storage tank calibration methods  while the BMS detection module can meet the requirements of measurement accuracy, must be calibrated before and after ex factory on BMS.

Electric pumps selection basis

Suitable for small and medium sized pumps around auto fuel dispenser agricultural stations, supply and marketing cooperatives, factories and mines fleet vehicles, ships and other units sucking various oil, such as gasoline, diesel, kerosene, oil, food oil, paper introduces electric pumps the selection basis, as follows:
According to the process, drainage requirements, from five aspects to consider the amount of liquid delivery device head, fluid properties, piping layout and operating operating conditions;
Flow is selected barrel pump head is another important performance data for key performance players move one data device system pumps required, the general use of amplified 5% -10% margin lift for selection;
Fluid properties, including liquid media name, physical properties, chemical properties and other properties;
Piping layout condition barrel pump device system refers to the highly liquid feeding liquid feed liquid feed to the distance to fuel management solutionshead

Gear pump technology introduced

Difficult technical problems, gear tank automation system inlet valve DAPIV innovative design greatly reduces the valve may be stuck in the paint, with high-power electric motor and a sturdy molded enclosure, Kan Bell sprayer can do many tasks of short duration high the amount of construction work. Nozzle is another significant factor affecting the quality of the coating. Its quality evaluation for resistance to abrasion, even atomization nozzle American worthy Bell products by carbide manufacturing, wear resistance, high coating quality, the price is relatively cheaper and more powerful gear pump diaphragm to become the shining coating machinery person! pneumatic diaphragm pump gear is a new transport machinery, is currently one of the most innovative gear pump classes. Using compressed air as a power source for a variety of corrosive liquid with particles, high viscosity, volatile, flammable, poisonous liquid can be tank level gauge systemoptical absorption Jing.

Temperature measurement calibration

Thermodynamicmarine fuel dispensers(symbol T) is the physical fundamentals hand, its unit 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 with 273.15K (freezing) to represent the difference between the petrol dispenser pump, so it retains all methods. By definition, equal to the size of degrees Kelvin, the temperature difference can also be expressed in degrees Celsius or Kelvin to represent. International Temperature Scale ITS-90 also defines international Kelvin (symbol T90) and the International Celsius (symbol t90)

temperature probe calibration

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. Material Velocity Calibration 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 measurement is 100, velocity values ??obtained at this time is the actual velocity values ??of the material. Probe Zero calibration measurement state maintained above the gate way to the positive or negative, so that the state regulate the fuel meters zero sound path measurement line again to 100, the probe zero value is zero at this time to get the value of the diesel meter. There are many oblique probe calibration method does not completely block the test stick using standard calibration, the calibration may be performed using the known depth of the hole, in theory, the reference reflecting body is smaller, the higher the accuracy of calibration, 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.
