Micro volume flowmeter model

Date:2019-12-11 source:

The micro-volume flowmeter is a kind of total flow meter that measures the total flow result very accurately. The measurement accuracy is very high, which can exceed 0.2 level.Now in the oil and gas field system open to the outside world in the oil work transfer metrological verification of a wide range of applications, a long time flow meter, its design scheme technology and manufacturing processing technology has been relatively perfect, is widely accepted by the sale of a flow meter.

Micro-volume flowmeter measurement structure:

Pedal flowmeter belongs to the volumetric flowmeter, which is of high accuracy in the total flow meter. It is suitable for the measurement of the total flow of low-viscosity substances, but the sense of discomfort is used for the fluid mechanics with solid particles. The key is composed of the measuring room, sealing tissue and counting tissue.

1. Measuring room: the instrument body is made of pig iron, and its inner wall and rear cover plate constitute the measuring room.There are two stainless steel plate axles in the measuring room, and a pair of elliptic transmission gears are set on the axles, which are rotated by the pressure difference between the inlet and outlet of the flow meter, and then the liquid at the inlet is continuously sent to the inlet and outlet after the measurement verification of the crescent-shaped bone cavity. The volume of the crescent-shaped indoor space is four times as much as the volume of the crescent-shaped indoor space after every rotation.The gap between the oval drive gear and the inner wall of the measuring room is not large, only a few microns, to reduce the leakage of the meter.

2. Sealing organization: the measuring chamber of the instrument is closed.Diameter flowmeter selected * belt magnetic sealing organization: by the baffle will be positive * magnet, general attack * magnet separation.The structure has high sensitivity and reliable sealing.Polytetrafluoroethylene (ptfe) is used as packing seal for large size flowmeter: according to adjusting the nut to change the reduction amount of elastic yellow, so that the sealing gasket is extended, exceeding the purpose of sealing.The structure is very simple and easy to adjust.

3. Counting organization: the counting organization of the instrument includes traditional gear train, reduction ratio adjustment organization and clearing organization.The number of a pair of elliptic transmission gear rotation, and the speed of rotation by the transmission gear system speed adjustment after the transmission to the clearing organization of the needle and word wheel, you can understand the total output of the liquid in the pipeline and instantaneous speed of the total flow.

Porcelain city Shanghai instruments co., LTD., founded by former Siemens MrStone senior engineers, specializing in high quality, high precision, wide range of flow meter of the research and development and production work, independent research and development of our products enjoys a high reputation in the industry, small flowmeter development make up the blank of domestic small flow meter, the quality of the product can completely replace the Max, KRACHT (clark), OVAL and other international brands.
