1. What are the types of volumetric flow meters?
A small volumetric flow meter is a highly accurate total flow measurement instrument that can measure total flow with an accuracy of over 0.2 levels. Nowadays, it is a widely used and long-lasting flow measurement instrument in the transfer and calibration of petroleum work in the open oil and gas field system. Its design scheme, technical aspects, and production and processing technology have been relatively improved, making it a widely accepted flow measurement instrument for both buyers and sellers. Micro volume flowmeter model: Measurement structure of micro volume flowmeter: Foot operated flowmeter belongs to a type of volumetric flowmeter, which is a high-precision instrument in total flow meters. It is suitable for measuring the total flow of low viscosity substances, but it is not suitable for fluid mechanics with solid particles. The key components are the measuring chamber, sealing structure, and counting structure.
1、 Measurement room: The instrument body is made of pig iron, and its inner wall and rear cover plate form the measurement room. There are two stainless steel plate shafts in the measurement room, and a pair of elliptical transmission gears are fitted on the shafts. They are driven to rotate by the pressure difference at the inlet and outlet trade points of the flowmeter, and continuously send the liquid at the inlet to the inlet and outlet after being measured and calibrated by the crescent shaped bone cavity. For each rotation, the total volume of the crescent shaped indoor space is four times. The gap between the elliptical transmission gear and the inner wall of the measuring room is not large, only a few tens of microns, to re
2、 Sealed organization: The measuring chamber of the instrument is enclosed. The caliber flowmeter adopts a magnetic sealing structure with a baffle to separate the positive magnet and the general magnet. This structure has high sensitivity and reliable sealing performance; Large scale flow meters use polytetrafluoroethylene plastic as the packing seal: adjust the nut to change the shrinkage of the spring yellow, so that the sealing gasket extends beyond the sealing target. This structure is very simple and easy to adjust.
3、 Counting organization: The counting organization of the instrument includes the conventional gear train, reduction ratio adjustment organization, and clearing organization. The number of rotations of a pair of elliptical transmission gears and the speed of their rotation can be transmitted to the clearing organization through the transmission wheel system to determine the total liquid production and instantaneous velocity total flow rate in the pipeline. Shanghai Cixi Instrument Co., Ltd. was founded by Mr. Stone, a senior engineer at Siemens, specializing in the research and production of high-quality, high-precision, and wide range flow meters. Our independently developed products are well-known in the industry, and the research and development of small flow meters fills the gap in domestic small flow meters. The product quality can completely replace international brands such as Max, KRACHT, OVAL, etc.
What is the maximum flow rate of a DN25 gas flowmeter?
The maximum flow rate varies depending on the type of flowmeter.
. Glass rotor cover flow meters, metal tube Shilu rotor sealing strip flow meters, and so on can all measure
