According to the verification regulation of National Velocity Type and volume type flow meter, this device can be used to check the gas flow meters of Turbine flow meter, vortex flow meter, impeller flow meter, precession vortex flow meter and volume flow meter, industrial film flow meter, etc
On the premise of verifying different types of flow meters, the device features low accuracy, a wide range, a high degree of automation, many types of instruments being tested, and a novel structure. It can be used in the verification and test of gas flow meter in petroleum, chemical industry and City Natural Gas Industry In particular, it is suitable for many kinds of flow meters being checked, a wide range of verification work area, a large amount of flow meter verification units, natural gas companies and large-scale industrial and Mining Enterprises
- The nozzle has a simple structure, is strong and durable, is easy to copy and test, and the uncertainty of its outflow coefficient is ≤0.2
- The device has a compact structure, good repeatability, and reliability
- When the device is working, multiple nozzles can be combined freely according to the flow rate, so the measuring range is wide. The lower limit is 1m / h, the upper limit is selected below the maximum flow rate of the device
- The temperature transmitter and differential pressure transmitter with high precision are adopted, and the measured data are averaged many times to ensure the accuracy of the collected data
- In the process of flow verification, the advanced pulse interpolation technology is used for pulse counting to ensure the readiness of the measured flow pulses
- Freely choose the flow meter verification time, Verification Volume, flow points, etc. , greatly facilitate user operation
