The LZYN type mass flowmeter (also known as the Coriolis mass flowmeter, hereinafter referred to as the flowmeter) is a self selected national 863 research and development project of our company, which was once part of the Ministry of Science and Technology and four other departments
The national key new product recognized by the committee once won the first place in the bidding of Sinopec’s daily procurement framework agreement
The flowmeter is a high-tech product that uses the Coriolis force principle to measure flow. It has completely independent intellectual property rights and has obtained multiple invention patents and utility model patents. The flowmeter has been widely used in process detection and trade transfer measurement in industries such as petroleum, petrochemicals, chemicals, ships, pharmaceuticals, municipal administration, papermaking, food and energy. It has been highly valued by the flow measurement community at home and abroad and welcomed by the majority of users. It is a relatively advanced and rapidly developing new type of flow measurement instrument in the world today.

Compared with traditional flow measurement methods, flowmeters have obvious advantages. Flowmeters can directly measure the mass flow rate of fluids in pipelines without the need for conversion of intermediate parameters, thus avoiding measurement errors caused by intermediate links. Its mass flow measurement has high accuracy and good repeatability, and can achieve high-accuracy direct measurement of fluid mass flow rate within a relatively large range ratio. The flowmeter can measure a wide range of fluids. In addition to measuring uniform fluids of general viscosity, it can also measure various high-viscosity and non-Newtonian fluids. For slurries containing solid phase components and fluids containing trace gas phase components, it can also be used under certain conditions.
The vibration amplitude of the flow meter's measuring tube is small and can be regarded as a non-moving part. There are no obstructions or moving parts inside the flow meter pipe through which the fluid flows, so it has high reliability, long service life, and low daily maintenance.
In addition to directly measuring the mass flow rate of the fluid, the flow meter can also directly measure the density and temperature of the fluid. It can also derive the concentration of the solute in the two-component solution from the mass flow rate and fluid density, accurately analyze the water content of crude oil, and provide display and output of multiple parameters. It is a multi-functional flow measurement instrument.
