Super-minor-caliber three-diamond-type flowmeter

Abstract

The invention relates a super-minor-caliber three-diamond-type flowmeter. The super-minor-caliber three-diamond-type flowmeter is installed inside the surface body of a diversion pipe. Differential pressure division pipes are connected on the surface body of the diversion pipe. The three-diamond-type flowmeter is in a circular structure. The diameter of the three-diamond-type flowmeter is in accordance with the inner diameter of the surface body of the diversion pipe. A round hole is formed in the centre of the three-diamond-type flowmeter. Six round holes are symmetrically distributed around the round hole. A regular hexagon shape is formed by the six round holes. Compared with the prior art, the super-minor-caliber three-diamond-type flowmeter is compact in structure and skillful in design. Due to the fact that the rectification and the detection are combined into one, the accuracy and repeatability of a measurement are increased. The super-minor-caliber three-diamond-type flowmeter has the advantages of being wide in measuring range ratio, small in loss of pressure, abrasion resistant, long in service life, short in an installation straight pipe section and the like.

Description

Technical field [0001] The invention relates to the technical field of flow detection, in particular to a Mitsubishi flowmeter with an ultra-small diameter. Background technique [0002] The traditional flow differential pressure device (also called throttling device) is used to detect fluid flow. Although it has made important contributions to flow measurement in a certain period of time after a long development process, it has not solved the problem of low measurement accuracy and measurement range. A series of problems such as narrow temperature, easy to wear, high pressure loss, high requirements for on-site installation of straight pipe sections, especially in the detection of small diameter and small flow, traditional differential pressure flowmeter products are still blank, and the market measures small diameter flowmeters. The flow requirements are getting higher and higher, such as bio-pharmaceuticals, fine chemicals, scientific research institutions, and automotive air ...

Problems solved by technology

[0002] The traditional flow differential pressure device (also known as throttling device) is used to detect fluid flow. Although it has made important contributions to flow measurement in a certain period of time after a long development process, it has not solved the problem of low measurement accuracy and measurement range. A series of problems such as narrow width, easy wear, large pressure loss, and high requirements for on-site installation of straight pipe sections, especially for small-caliber micro-flow detection, traditional differential pressure flowmeter products are still blank, and the market for small-caliber flowmeters to measure tiny The flow requirements are getting higher and higher, such as biopharmaceuticals, fine chemicals, scientific research institutions, and automotive air flow meters in the automotive industry, etc.
