1. Principle of Zhejiang Cangnan Gas Meter

Zhejiang Cangnan Instrument Factory mainly produces these gas flow meters: gas turbine flow meter, gas Roots flow meter, and gas vortex street flow meter are flow meters that measure fluid flow in closed pipelines based on the Karman vortex principle. Gas Roots flowmeter is an instrument for accurately measuring gas flow rate, based on the principle of volumetric measurement, for accurately measuring the total amount of Peikai gas flowing through closed management.

2. Development History of Tianxin Instrument Group Co., Ltd.

The development history of Tianxin Instrument Group Co., Ltd. is as follows: Initial stage: In 1995, Cangnan County Three Dimensional Instrument Co., Ltd. was established as the predecessor of Tianxin Instrument Group, with an initial capital of 500000 yuan and more than 20 employees. Its main product is rotary vortex flowmeter.

. Through technological innovation and self-development, preliminary accumulation has been completed. Rapid development stage: In 1998, Zhejiang Tianxin Instrument Co., Ltd. was established by merging Cangnan County Pailuo 3D Instrument Co., Ltd. and Cangnan Huayu Instrument Co., Ltd., and increasing capital and shares to acquire the state-owned Cangnan Instrument Factory 3. At the same time, Shanghai Tianxin Energy Equipment Co., Ltd. and Cangnan Tianxin Software Development Co., Ltd. were established, and the scale of the enterprises rapidly expanded. Accelerated stage of internationalization process: From 2002 to 2007, Tianxin Group aimed at internationalization goals and cooperated with the internationally renowned instrument manufacturing enterprise Dresser in the United States to produce Roots flow Roots flowmeter manufacturer

meters. It also formed strategic partnerships with global gas equipment manufacturers, introduced advanced technology and production management experience, and achieved brand enhancement and accelerated internationalization process. Diversified operation stage: Since 2007, Tianxin Group has entered the diversified operation stage and successively established multiple subsidiaries such as Zhejiang Tianxin Electric Co., Ltd. and Shanghai Tianxin Instrument Co., Ltd. The business scope covers multiple fields such as gas measuring instruments, industrial measuring instruments, gas pressure regulating equipment, etc. It also ventures into automation control systems, software product development, motor protection devices, real estate development, and financial investment. In 2008, the groups subsidiary chain was promoted to a national non regional enterprise group, entering a new stage of diversified operations.

3. What is the working principle of the waist wheel flowmeter? The waist wheel flowmeter, also known as the Roots flowmeter, works based on one or two pairs of waist wheels that can rotate tangentially. Its internal structure includes a measuring chamber, which is composed of the outer edge of the waist wheel and the inner wall of the shell, forming a "bucket" space with a fixed volume. When the fluid passes through under the pressure difference, the waist wheel will rotate in the positive direction. The working process of the waist wheel can be divided into four stages: firstly, the waist wheel Q1 acts as the driving wheel, pushing Q2 to rotate and discharge the fluid from the measuring chamber; Next, Q2 becomes the driving wheel and repeats the above process. Each waist wheel rotates 180 degrees to complete o
