What aspects can be used to determine the specifications of a rotor flowmeter? The specifications of the rotor flowmeter can be selected from three aspects: medium temperature and pressure. The next step is to measure whether the diameter of the stove needs to output a signal. 2. Differences between Orifice Flow Meter, Venturi Flow Meter, and Rotary Flow Meter
Orifice Flow Meter, Pitot Tube, Venturi Flow Meter, and Rotary 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
3. Working principle of rotor flowmeter
The rotor flowmeter consists of two components, one of which is a conical tube that gradually expands from bottom to top;
; The other component of the rotor flowmeter is a rotor that is placed in a conical tube and can move freely along the centerline of the tube. When measuring the flow rate of a fluid, the measured fluid flows in from the lower end of the conical tube and impacts the rotor, generating a force on it (the magnitude of which varies with the flow rate); When the flow rate is large enough, the generated force lifts the rotor and raises it. At the same time, the measured fluid flows through the annular section between the rotor and the conical tube wall, and there are three forces acting on the rotor: the dynamic pressure of the fluid on the rotor, the buoyancy of the rotor in the fluid, and the gravity of the rotor itself. When the flowmeter is installed vertically, the center of gravity of the rotor coincides with the axis of the cone tube, and the three forces acting on the rotor are parallel to th
