Description

Dual purpose electromagnetic flowmeter

technical field

The utility model relates to measuring instrument technology, in particular to a dual-purpose electromagnetic flowmeter technology.

Background technique

The electromagnetic flowmeter is an instrument used to measure the flow of fluid. When it is used, it is connected to the flange of the pipeline to be tested to measure the flow of the medium in the pipeline to be tested. The electromagnetic flowmeter is mainly composed of a flow sensor and a flow converter. The existing electromagnetic flowmeters directly fix the flow converter on the flow sensor. The flow converter cannot be used separately from the flow sensor, which is not conducive to obtaining flow data in some applications. , which brings inconvenience to the use of the flowmeter, and the display screen of the existing electromagnetic flowmeter is fixed on the flow converter. When installed on a horizontal pipe, the displayed data on the display screen is correct, but when installed on a vertical pipe or an inclined pipe, the displayed data on the display screen is skewed.

Utility model content

Aiming at the above-mentioned defects in the prior art, the technical problem to be solved by the utility model is to provide a dual-purpose electromagnetic flowmeter which is convenient to use.

In order to solve the above-mentioned technical problems, a dual-purpose electromagnetic flowmeter provided by the utility model includes a flow sensor and a flow converter. The display screen rotates left and right, and a connecting hole is opened on the shell of the flow converter, and the connecting hole is fixed with a first connecting flange;

One end of the connecting pipe is fixedly connected to the casing of the flow sensor, and the other end of the pipe is fixed with a second connecting flange, and the flow converter and the connecting pipe are fixed in a detachable manner through the cooperation of the first and second connecting flanges Connection, the signal lead wire of the flow sensor passes through the lumen of the connecting tube and the connection hole on the flow converter casing to connect to the flow converter.

Further, the outer surface of the flow converter has two color-jumping areas, and the two color-jumping areas are painted with two different colors.

Further, the displayed display screen is provided with four function keys, and the four function keys are symmetrically arranged at four corners of the display screen.

The dual-purpose electromagnetic flowmeter provided by the utility model is equipped with a connecting pipe on the flow sensor, and the flow converter is installed on the connecting pipe through the connecting flange, which can be disassembled and used separately according to the needs, and the display screen can be rotated according to the actual needs. Ensure that the display data on the display screen is correct, and it is easy to use.

Description of drawings

Fig. 1 is a schematic structural view of a dual-purpose electromagnetic flowmeter according to an embodiment of the present invention.

Detailed ways

The embodiments of the present utility model are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present utility model. All similar structures and similar changes of the utility model should be included in the protection of the utility model. scope.

As shown in Figure 1, a dual-purpose electromagnetic flowmeter provided by the embodiment of the utility model includes a flow sensor 1 and a flow converter 2, and is characterized in that: the flow sensor 1 is provided with a connecting pipe 3, the A display screen 4 capable of rotating left and right is installed on the flow converter 2, and a connecting hole is opened on the shell of the flow converter 2, and the connecting hole is fixed with a first connecting flange;

One end of the connecting pipe 3 is fixedly connected to the shell of the flow sensor 1, and the other end of the nozzle is fixed with a second connecting flange. It is fixedly connected in a detachable manner, and the signal lead wire of the flow sensor 1 passes through the lumen of the connecting pipe 3 and the connection hole on the casing of the flow converter 2 to connect to the flow converter.

In the embodiment of the present utility model, the outer surface of the flow converter 2 has two color-jumping areas, and the two color-jumping areas are painted with two different colors.

In the embodiment of the present utility model, the display screen 4 is provided with four function keys 5, and the four function keys are symmetrically arranged at the four corners of the display screen.

The embodiment of the utility model is suitable for measuring the medium flow in the pipeline, and the first and second connecting flanges can be loosened, so that the flow converter can be removed from the connecting pipe so that it can be used independently from the flow sensor. The direction of the pipeline under test is rotated to ensure that the displayed data on the display is correct.
