1. How to draw the calibration curve of a Venturi flowmeter

1. Turn on the oil-free gas compressor and let in air.

2、 Adjust the adjusting screw at the lower end of the rotor flowmeter and the spiral clamp on the relief valve on the vent rubber tube to change its body flow rate.

3、 Draw the route of the curve.

2. Doppler flowmeter

3. Double rotor flowmeter 2, working principle

Double rotor flowmeter is a uniquely designed volumetric flowmeter specifically used for measuring liquid flow rate.

. Its working principle is based on the meshing of a pair of spiral rotors with special tooth profiles, and there is no relative sliding between the two, without the need for synchronous gears. The rotational power source of the rotor comes from the small pressure difference generated by the fluid at the inlet and outlet. As shown in the figure below, at a certain moment on a certain cross-section, although a pair of rotors experience different fluid rotational torques, the resultant torque of the rotational torques on all cross-sections remains equal for both rotors. Therefore, the two rotors rotate at a constant speed and equal torque to ensure balanced displacement without pulsation. Each rotor can output 8 times the volume of the ca

vity per revolution, therefore, the rotational speed of the rotor is proportional to the cumulative flow rate of the fluid, and the rotational speed of the rotor is proportional to the instantaneous flow rate of the fluid. The rotational motion of the rotor is transmitted to the meter counter through a magnetic coupling, and the counter displays the flow rate through the flowmeter (flowing through the pipeline). This design enables the dual rotor flowmeter to have high precision, stability, and reliability, making it suitable for various industrial applications. Dual rotor flow meters can be divided into two forms based on their structure: standard type and axial flow type. The standard dual rotor flowmeter is shown in the figure and is suitable for general liquid flow measurement. Axial flow dual rotor flowmeter has higher measurement accuracy and wider flow range, especially suitable for occasions with strict requirements for flow measurement. The dual rotor flowmeter, as a highly efficient and accurate liquid flow measurement tool, is provided by Shanghai Youhe Industry. Its unique design and high performance make it an ideal choice in many industrial fields, widely used in multiple industries such as petroleum, chemical, pharmaceutical, food, and environmental protection.
