1. Difference between gas turbine flowmeter and gas waist wheel flowmeter
Hello, KNKE, an American imported turbine flowmeter manufacturer, is pleased to answer your question. The measurement principles and structures of flow sensors for gas turbine flow meters and gas waist wheel flow meters are significantly different, and their measurement accuracy is affected by the friction torque of the impeller (waist wheel) and bearings, the flow resistance torque generated when gas passes through, and other resistance torques.
1、 The principle and structure of gas turbine flowmeter. Gas turbine flowmeter is a velocity flowmeter that must have sufficient length of front and rear straight pipe sections when installed and used. The measurement principle is to use the mathematical relationship between the rotational speed of the impeller in the fluid and the fluid velocity, and to reflect the flow rate by measuring the rotational speed of the impeller. It is currently a mature and high-precision measuring instrument in flow meters. It mainly includes built-in rectifiers, turbine blades, transmission mechanisms, magnetic coupling transmission mechanisms, counters and other components. Additional devices such as low-frequency pulse, A1S high-frequency pulse generator, A1R high-frequency pulse generator can be selected according to actual needs. 2. Principle and structure of gas waist wheel flowmeter. Gas waist wheel flowmeter is a volumetric flowmeter with high accuracy, wide range ratio, and high reliability. When installed slowly, it does not require high requirements for the front and rear straight pipe sections. The measurement principle is that a pair of "∞" - shaped rotors, namely waist wheels, rotate synchrono
2. Which is a good gas turbine flowmeter?
Your model source is good. The American imported gas turbine flowmeter manufacturer, KNKE, is pleased to answer your question.
. There are many manufacturers of turbine flow meters. In this answer, we recommend the KNKE brand turbine flow meter from the United States. The reasons are as follows:1. The pressure loss is relatively small: generally between 0.1 and 2.5 kPa under normal pressure. 2. High accuracy: The full range is generally 1% -2.0%, and the high-precision type is 0.5% -1.0%; It belongs to a type of high accuracy. 3. Compact structure, lightweight volume, easy installation and use, and high circulation capacity. 4. Good repeatability: generally up to 0.05% to 0.2%. Due to its good repeatability, it can achieve * accuracy through regular calibration or onl
