Why cannot liquid turbine flow meters be used to measure high viscosity media? The main reasons why liquid turbine flowmeters cannot be used to measure high viscosity media are as follows: 1. Inaccurate measurement: Liquid turbine flowmeters measure fluid flow based on the rotation principle of the turbine. The flow resistance of high viscosity media is relatively high, which can cause the rotation speed of the turbine to slow down, thereby affecting the accuracy of measurement. 2. Pressure loss: High viscosity media can cause significant flow resistance during the flow process, requiring greater driving pressure to maintain fluid flow in the turbine flowmeter, resulting in greater pressure loss. 3. Reliability and durability: High viscosity media require higher construction and material requirements for the old coarse turbine flowmeter to ensure its reliability and durability in high viscosity environments. Some liquid turbine flow meters may not meet these requirements, resulting in unstable measurements or equipment damage. 4. Turbine blade blockage: High viscosity media may cause turbine blade blockage, further affecting the normal operation of the flow meter. 5. Cleaning difficulties: High viscosity media may leave deposits inside the flow meter, making cleaning difficult and affecting subsequent measurements. For flow measurement of high viscosity media, it is usually necessary to choose a suitable type of flowmeter, such as upright float flowmeter, submerged float flowmeter, liquid expansion flowmeter, etc. These flow meters are more suitable for handling high viscosity media because their structure and working principle are different from turbine flow meters, which can better adapt to the measurement requirem

3. Requirements for the use parameters of turbine flow meters.
The use parameters of turbine flow meters must be strictly matched with the characteristics of the medium, working conditions, and installation requirements. The core of the core is to ensure measurement accuracy and instrument life.
. 1. Medium adaptation parameters Bi Chan • Liquid medium: viscosity should be ≤ 50mm ²/s, and when it is higher than 5 × 10 ⁻⁶ m ²/s, it must be calibrated with real liquid. Corrosive liquids must be used for instruments made of 316L or Hastelloy materials. • Gas medium: must be clean and dry, with impurities or easily condensable gases requiring the installation of precision filters, and not suitable for dirty media
2. Matching parameters for working conditions • Flow range: Liquid measurement should be maintained within the range of 10% -90%, gas is recommended to be 20% -80%, to avoid low flow rate failure or high flow rate wear. • Pressure and temperature: The working pressure and temperature should not exceed the rated value of the instrument (refer to the product manual for details, such as the common upper pressure limit of 1.6-6.4MPa). • Pipeline diameter: It must be consistent with the instrument diameter, and the length of the variable diameter section must be ≥ 10 times the pipe diameter when changing diameter
3. Accuracy and installation parameters • Accuracy level: Measurement level uses ≤± 0.5% FS, and industrial control can choose ± 1% FS. • Straight pipe section requirements: front straight pipe section 10D-15D (D is the pipe diameter), rear straight pipe section 5D, to
