Domestic and international brands of helical gear flow meters

The FPP elliptical gear flow meter is a professional volumetric flow meter for which patents have been granted in the United States. FPPMETERS was established in 1987; it is a business unit of the renowned TUTHILL Transfer Systems (abbreviated as TTS) in the United States. Its factory is located in Louisiana, New Orleans, covering an area of 20,000 square feet. Initially, the company was owned by ROCKWELL, but it was acquired by TTS in 1996. FPPMETERS is dedicated to manufacturing flow meters with an excellent cost-performance ratio, which are widely used in various fields such as oil and gas, general industry, retail trade, and municipal engineering services. FPPMETERS is the fastest-growing manufacturer of gear flow meters in the United States. Leveraging years of accumulated engineering experience, the engineers at FPPMETERS have successfully developed a new generation of elliptical gear designs that have been patented in the United States for the 21st century. With this design, the flow meter operates more smoothly and with higher accuracy, while component wear and pressure losses are reduced. The principle of measurement: The principle behind elliptical gear flow meters is one of the oldest designs for measuring volume flow. However, through the efforts of FPPMETERS engineers, a completely new type of elliptical gear flow meter has been developed – one that incorporates modern concepts and makes use of new materials and manufacturing techniques, fitting the needs of the 21st century. While maintaining the ability to measure viscosities and flow rates over a wide range, technological advancements have led to more compact designs and superior performance. FPPMETERS is thus able to proudly offer its customers the next-generation helical gear technology covered by a U.S. patent. Its feature: Accuracy. Its unique design meets the requirements of virtually all measurement standards, whether measuring liquids with high or low viscosity. Once installed, it operates quietly and accurately, and its easy maintenance features mean that you’ll hardly notice its presence as it carries out its functions day after day. Simplicity. The flowmeter of FPPMETERS has only two rotating components in the measurement chamber, so it hardly ever experiences downtime. If necessary, the economical repair parts, along with the feature of not requiring removal from the workplace, enable flow meters to be owned and operated more cost-effectively. Economy – low cost and high precision. The flow meters from FPPMETERS offer high precision at a low cost. Their affordable initial investment, long service life, and easy maintenance make them a wise and natural choice for a wide range of customers. Application areas. The FPPMETERS flowmeters come in a range of flow rates, and various materials and configurations are available for use with acetates, alcohol, diesel fuel, aviation fuel, corrosive substances, corn syrup, diesel, fertilizers, fuel oil, gasoline, ethylene glycol, herbicides, honey, latex, liquid saccharin, kerosene, paint, pesticides, plasticizers, inks, resins, solvents, vegetable oils, and water. They can also be used as standard meters in measurement departments. Application method. Canning, batch and mixed loading, large-scale loading, fuel consumption, high-speed refueling, inventory control, flow control, fuel receipt, tank containers and transportation services. With over 50 years of experience in the professional design and manufacturing of positive displacement flowmeters, the elliptical gear flowmeters we offer range from 1/4 inch to 3 inches in diameter, with flow rates spanning from 0.1 liters per minute to 950 liters per minute

I’ve learned it, thank you to the original poster; I hope more good materials will be uploaded in the future.

Are there any other foreign brands? Just these few companies?

German FLUX helical gear flow meters – German technology and fairly good quality

Are there any differences in product performance and price between OVER in Japan, FLUX in Germany, and GPI in the United States? Which company has stronger performance in China?

What are the brands of internal gear flow meters available in China? What are the technical features?

In China, there is Obal in Hefei; Oval from Japan is also good

There is the Hefei Jingda Instrument Factory in China~~ But I’m not sure who exactly is this Obal in Hefei mentioned on the 10th floor Is it the same company as Jingda?

The OVAL in Hefei is a factory established by the Japanese company OVAL as a wholly-owned enterprise in China; it also produces products under the OVAL brand. However, these are domestically produced items, and their quality and price are lower compared to the original versions.
