Liang Buwei only be required taximeter inspection once a year

Normal conditions, the use of \And I will use portable ultrasonic flow meter per month on more than one water meter DN80 comparison test periodically. The DN400 meter test results last month as follows: when asked on January 2 Month 3 Months April 5 Months 6 Months July 8 月 September 11 月 December lO soup chu. 4-3.5-3.7-3.1-3.2-, small. s one. 2s based on the results of tests on the table, I still think that this water may have emerged the phenomenon of tolerance. Therefore, or break it back to the check station test, test result: the meter has failed, a portable ultrasonic flow meter to get it out. 5 Conclusion Given the use of medium and large caliber water meter on-site conditions, it is difficult for online calibration. The projects, generally not suitable for long without water, check back often split Taiwan test seems unrealistic. Therefore, effective on-line water meter testing is particularly important, hope that this \But no matter what way, I believe that ultimately the check station's findings as the standard.

After detection is complete, turn off the computer sends test instructions, testing process is complete. Software flow shown in Figure 5. Figure 5 system software flow chart 3 Conclusion The system uses PxI /, GPIB bus and PXI modules hybrid instruments, the use of VPC90 adapter and the corresponding switch to connect the controller and the UAV test equipment, unmanned aerial vehicles under software control automatic detection of various subsystems to enhance the practicality of the detection system.

Meter sales in 2005 leveled the country continue to maintain large dominant position in Zhejiang in 2005, the national energy meter industry sales remained stable trend. According to the Chinese instrument can form 37,073,000 units, electronic energy meter 50,590,300 units, the total output of electronic instruments form industry associations in the electrical branch of the National Statistics 76 major manufacturers (including Ningbo, a further rise in the proportion to the amount of 57 .71%. Samsung technology companies electrical branch of the data are not statistics, joined by the branch) all year round production of electricity meter large proportion of Zhejiang Province, to continue to maintain a greater dominance of the former sheet production was 87,663,300 Taiwan, an increase of 6.8% over the previous year, of which 20 large electric induction occupied an important position scale enterprises.
