2. Differences between orifice flow meter, Venturi flow meter, and rotor flow meter
Orifice flow meter, pitot tube, Venturi flow meter, and rotor flow meter are all tools used to measure flow rate, but there are some differences in their working principle, scope of application, measurement accuracy, and service life due to chain breakage. 1. Working principle: The orifice flowmeter measures the flow rate by utilizing the local pressure difference generated by the orifice plate holes. The pitot tube utilizes relative motion between a fluid in motion and a stationary object to measure velocity and flow rate. The Venturi flowmeter measures the flow rate by utilizing the pressure difference generated by the high-speed moving fluid in the contraction section of the pipeline. Rotary flowmeter uses the volume of liquid flowing through the rotor to achieve flow measurement. Scope of application: Orifice flowmeter is suitable for measuring medium and high viscosity liquids and gases. Pitot tubes can measure the flow rate and flux of various liquids and gases. The Venturi flowmeter is suitable for measuring low to medium viscosity liquids and gases, with minimal pressure loss in shed pipelines and higher accuracy than orifice plates under large pipe diameter conditions. Rotary flow meters are suitable for measuring liquids and gases with high viscosity. Measurement accuracy: Generally speaking, the accuracy of rotary flow meters is relatively high, and the measurement accuracy of orifice flow meters under low flow rate and high viscosity fluid conditions will be greatly affected. The manufacturing cost of Venturi flow meters is relatively high. In general, orifice

3. What are the characteristics of a rotor flowmeter and what should be noted when using it?
Performance characteristics: A rotor flowmeter is the most commonly used flowmeter in industry and laboratories.. It has the characteristics of simple structure, intuitive, low pressure loss, and easy maintenance. Rotary flow meters are suitable for measuring small flow rates through pipelines with a diameter of D<150mm, and can also measure the flow rate of corrosive media. When in use, flow meters are generally installed on vertically oriented pipe sections, and the fluid medium passes through the rotor flow meter from bottom to top. Specially designed rotor flow meters can be installed horizontally or vertically with upper inlet and lower outlet. Installation precautions: In order to ensure the normal operation of the rotor flowmeter and achieve a certain measurement accuracy, the following points should be noted when installing the flowmeter:
1. The rotor flowmeter must be installed vertically on a vibration free pipeline. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2 °. When installed horizontally, the horizontal angle is better than 2 °; (There are now horizontally installable rotor flow meters)
