Abstract
Claims
1. A straight tube float flowmeter characterized by, Its structure includes a fluid inlet, a measuring tube, a measuring chamber, a float, a float connecting rod, an induction magnet, a linear Hall sensor assembly, a conduit, a float connecting rod fixing sleeve, a triangular support frame, a fluid outlet, and a digital display instrument. The fluid inlet is the inlet for fluid to enter a straight-tube float flowmeter, and the fluid outlet is the outlet for fluid to exit. A measuring tube is located at the top of the fluid inlet, and a measuring chamber is located at the top of the measuring tube. A float is located inside the measuring chamber, and a float connecting rod is connected to the top of the float. An induction magnet is embedded in the top of the float connecting rod. A triangular support frame is located at the top of the measuring chamber, and a circular groove in the center of the triangular support frame is used to fix the float connecting rod fixing sleeve. A passage is located inside one corner of the triangular support frame, and a conduit is installed within the passage. The conduit contains the linear Hall sensor assembly, data transmission lines, and power lines, which are connected to the digital display instrument.
2. A straight tube float flowmeter according to claim 1 wherein, Fluid flows through the fluid inlet and then into the measuring tube, entering the measuring chamber. The fluid pushes the float upward. The linear Hall sensor assembly generates an electrical signal through the position change of the sensing magnet at the top of the float connecting rod. The digital display instrument calculates the real-time flow and cumulative flow based on the linear relationship between the signal strength of the Hall sensor assembly and the float displacement.
3. A straight tube float meter according to claim 1, wherein, The float is fixed to the induction magnet via a float connecting rod, and the linear Hall sensor assembly is installed inside the conduit, forming a non-contact displacement detection system with the induction magnet.
4. A straight tube float flowmeter according to claim 1 wherein, The overall structure of a straight-tube float flowmeter is made of corrosion-resistant and explosion-proof materials.
5. A straight tube float flowmeter according to claim 1 wherein, The digital display instrument is a device that integrates data acquisition, processing, and data transmission functions, as well as an independent power supply.
6. A straight tube float flowmeter according to claim 1 wherein, The fluid inlet is connected to the measuring tube, which is installed vertically in the measuring chamber.
