Summary
SYQB calibration device for the company's own design and manufacture, it selects the critical flow Venturi nozzle in accordance with international standards ISO9300 "critical flow Venturi nozzle gas flow measurement" as the standard meter, using the standard meter method for flow verification or testing. According to state regulations, speed type flowmeter calibration, the device of gas flow meter, turbine impeller, vortex, vortex precession speed meter and waist wheel, industrial diaphragm meter volumetric flowmeter factory inspection and periodic verification.
In order to meet the requirements of different types of flowmeters, the device has the characteristics of low uncertainty, wide range, high degree of automation, many kinds of instruments, novel structure and so on. The verification and test of gas flowmeter can be used in petroleum, chemical industry, natural gas industry in the city, especially suitable for many kinds of detected flowmeter and calibration range, measurement unit, flowmeter large amount of natural gas companies and large industrial and mining enterprises.
Product features
1, the nozzle structure is simple, strong and durable, easy to copy and test, the flow coefficient of uncertainty ≤ 0.2%.
2. The device has compact structure, good repeatability and reliability.
3, when the device works, according to the size of the flow can be freely combined with a plurality of nozzles, so wide measurement range. The lower limit is 1m 3/h, the upper limit of the maximum flow in the device selected.
4, the use of high precision temperature transmitter and differential pressure transmitter, and the measurement data using multiple average method to further ensure the accuracy of the collected data.
5, in the process of flow testing, the use of advanced pulse interpolation technology for pulse counting, to ensure the accuracy of the measured flow pulse.
6, the freedom to choose the flow meter verification time, verification volume, flow points, the number of times, greatly facilitate user operation.
7, the software is simple to operate, with the authority to operate, the user can configure the contents of the database according to the actual situation.
