Description

Float flowmeter

Technical Field

The utility model relates to a float flowmeter.

Background

The float flowmeter is a volume flow meter which is also called as a rotor flowmeter and measures by changing the flow area between a float and a vertical conical pipe as the float rises and falls along with the change of the flow. The flow detection element of the float flowmeter consists of a vertical conical measuring tube which is enlarged from bottom to top and a float group which moves up and down along the axis of the conical tube, and the structure is simple and compact; flow is usually judged by observing the position of the float relative to the scale marks on the taper pipe, so that the float needs to be observed on site manually, remote monitoring cannot be realized remotely, and further, remote flow control cannot be carried out according to remote monitoring data, so that the whole production operation efficiency of an enterprise is restricted.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, a float flowmeter includes a measuring tube 10, a tip assembly 11 disposed at both ends of the measuring tube 10, a float movably disposed inside the measuring tube 10, and a sensor for converting position change information of the float into an electric signal after the position of the float in the measuring tube 10 is changed, the sensor is in signal connection with a monitor (which may be a computer) at a far end, and flow information can be displayed on the monitor at the far end for remote display.

The sensor is a magnetic sensor 30. And the floater is a magnetic floater. The magnetic sensor 30 is widely used in modern industries and electronic products, and the magnetic sensor 30 is a device that converts the magnetic property change of a sensitive element caused by external factors such as magnetic field, current, stress strain, temperature, light, etc. into an electrical signal, and detects the corresponding physical quantity in this way; the utility model discloses a to adopt magnetic float, through the change of float position to magnetism through the float arouses that sensitive element magnetic property changes in the magnetic sensor 30, and converts this kind of change to current signal conveying to the monitor.

In this example, the float includes a case 20 having a cavity formed therein, a cover 21 capable of covering the case 20, and a magnetic body 200 (magnet) disposed in the cavity of the case 20, and the magnetic sensor 30 is detachably disposed on the side wall of the measuring tube 10, and in this example, the side wall of the measuring tube 10 is provided with scale marks for displaying the measured flow rate. That is, the magnet can be placed in the cavity of the housing 20 and also taken out of the cavity of the housing 20, and the magnetic sensor 30 can be detached from the housing 20; the float flowmeter of the utility model can be used as a common float flowmeter without remote function, and the position of the float relative to the scale mark can be observed on site to know the flow information; it is also possible to insert a magnet into the cavity of the housing 20 to cooperate with the magnetic sensor 30 for remote functions when remote functionality of the float flow meter is desired. The float flowmeter can have a remote function or not, the float flowmeter is manufactured for timing, two different production lines are not required to be arranged, and the production cost investment is reduced.

Furthermore, a clamping slide rail 101 extending along the axial direction of the measuring tube 10 is arranged on the side wall of the measuring tube 10, a clamping table 301 clamped with the two sides of the clamping slide rail 101 in a matched mode is arranged on one side of the magnetic sensor 30, the magnetic sensor 30 can be disassembled by clamping the clamping slide rail 101 and the clamping table 301 in a sliding fit mode, when the magnetic sensor 30 is disassembled and assembled, the end head assembly 11 at one end needs to be disassembled firstly, then one end of the clamping table 301 is aligned to one end of the slide rail 101, and the clamping table 301 slides into the slide rail 101 to be clamped with the end head assembly 11.

The tip assembly 11 and the measuring tube 10 are made of plastic, and the housing 20 and the cover 21 are made of plastic; the components are made of plastic, so that the normal and effective use of the magnetic sensor 30 can be ensured, and the magnetic interference is avoided.
