Can a DN150 caliber vortex flowmeter be used to measure sewage?
The maximum range of the DN150 caliber vortex flowmeter for measuring sewage is 400m3/h, and the minimum range is 40m3/h. The unit here refers to the calculation in cubic meters per hour. The range of the vortex flowmeter for measuring liquids is relatively large, so the DN150 caliber vortex flowmeter can be used to measure sewage as long as the measurement range is between 0-400m3/h.
2. Can you explain the full range measurement data of DN80 vortex flowmeter?
DN80 refers to the small flange of the vortex flowmeter, and DN80 also refers to the inner diameter of the pipeline being 80mm. From the measurement range, DN80 vortex flowmeter measures the small range of 12m3/h and the maximum full range of 120m3/h for the front body of the liquid sensing chamber. DN80 vortex flowmeter measures the small range of gas at 80m3/h and the maximum full range at 800m3/h.
3. Flow range of vortex flowmeter
The flow range of vortex flowmeter is mainly determined by the sensor diameter and fluid properties. The larger the diameter, the wider the measurable flow range.
. The conventional liquid measurement range is between 0.5m/s and 7m/s flow rate, and the gas measurement range is between 5m/s and 60m/s. 1. Correspondence between caliber and flow rate (under normal temperature water conditions) The flow range is directly related to the instrument caliber, and the following are typical parameters (referring to the product manuals of mainstream domestic manufacturers such as Chuanyi and Ganges in 2023): • DN15: minimum about 1.2 m ³/h, maximum about 15 m ³/h • DN25: minimum about 3 m ³/h, maximum about 40 m ³/h • DN50: minimum about_600x400.jpg)
3. Key selection principles • It is recommended to use the flow rate at 1/2 to 2/3 of the instrument range for normal use. Avoid long-term use below the lower limit of 20%, otherwise the signal stability will deteriorate and errors will increase. • The maximum flow rate shall not exceed 120% of the upper limit value of the instrument to avoid damage to the vortex flowmeter.
4. The extended range ratio of the standard vortex flowmeter is 1:10~1:15, and models using dual sensors or digital signal processing technology can be extended to 1:20~1:30 (such as Emerson high-precision models), but the price is higher. The actual selection should be strictly based on the calculation of medium operating parameters (temperature, pressure, density, viscosity). It is recommended to directly use the selection software provided by the manufacturer or check the latest version of the product manual to obtain accurate data.
