Problems solved by technology

Especially in the field of flow measurement, the structure and algorithm of the metal rotameter restrict the improvement of its accuracy. The metal rotameter may not have remote transmission function, which cannot meet the needs of users and also restricts the development of the instrument.
Although the mass flowmeter has a certain measurement accuracy, its development and market prospects are restricted due to its high cost.
Other flowmeters also have such defects or regrets as harsh media requirements, low precision, and poor stability.

Embodiment 1

[0078] The present invention is a float mass flowmeter, such as figure 1 as shown, figure 1 It is a structural representation of the present invention. Install the upper flange 1 to the upper port of the flowmeter pipeline 4 by screw connection, and fix the coil 3 to the appropriate position on the flowmeter pipeline 4 by using the fixing bracket 16. The fixing bracket 16 uses screws 17 Fasten and connect to the appropriate position on the flowmeter pipeline 4 and fix it close to the coil 3. Connect the lower flange 6 to the lower port of the flowmeter pipeline 4 with threads, and place the float 5 on the flowmeter tube. On the float stop ring 19 in the road 4, the float stop ring 19 is an open expansion ring installed under the flow meter pipeline 4 by the expansion force, and the instrument 2 is connected and installed on the flow meter pipeline 4 through the connecting screw 18. The position of the bracket 16.

Embodiment 2

[0085] The present invention is a metering method of a float mass flowmeter. In practice, the coil 3 is connected to the pulse output 10, and the main board CPU 9 sends a pulse with a given pulse width to the coil 3. The pulse width is adjustable according to The calculation result of the microprocessor determines how wide the pulse is. After the transmission is completed, the connection end of the coil 3 is switched to the connection sampling module 11 through the control of the mainboard CPU9 for sampling and analysis by the mainboard CPU9; the mainboard CPU9 finally transmits the analysis results. On the display panel 8, display the relevant content of the flowmeter through the display panel 8, and then transmit the relevant content of the flowmeter to the signal output 7 through the main board CPU9 for the user to use.

[0086] The invention is a metering method of a float mass flowmeter, comprising the following steps:

[0087] Step 1. Frequency domain analysis.

Abstract

The invention belongs to the technical field of instruments, meters and metering measurement, and particularly relates to a floater mass flow meter and a metering method. The flow meter comprises a flow meter pipeline, an upper flange and a lower flange, wherein the upper flange and the lower flange are connected to an upper port and a lower port of the flow meter pipeline respectively, a floateris arranged in the flow meter pipeline and arranged on a floater baffle ring connected in the flow meter pipeline; and an instrument and a coil are connected to the outer portion of the flow meter pipeline. When the flow is different, the position of the floater is changed, and the position of the floater is measured through the floater flow meter to calculate the flow, so that high-precision intelligent processing is achieved, and the functions of data storage, data query and the like are achieved. The flow meter is wide in application, is suitable for measuring various mediums, is not affected by the external temperature, is simple in structure, is reasonable in design, is convenient to use, is low in cost, is high in precision, and has a data remote transmission function. The application range is wide, the application prospect is quite considerable, and good economic benefits and social effects are achieved.

Description

technical field [0001] The invention belongs to the technical fields of instrumentation and metering, and in particular relates to a float mass flowmeter and a metering method. [0002] technical background [0003] In the era of rapid development of science and technology, the demand for intelligent instruments is becoming more and more obvious, and gradually replaces the old-fashioned instruments with low precision. Especially in the field of flow measurement, the structure and algorithm of the metal rotameter restrict the improvement of its accuracy. The metal rotameter may not have remote transmission function, which cannot meet the needs of users and restricts the development of the instrument. Although the mass flowmeter has a certain measurement accuracy, its development and market prospects are restricted due to its high cost. Other flowmeters also have such defects or regrets as harsh requirements on media, low precision, and poor stability. Contents of the invent...
