Flow meter with magnetic pointer

This creation is directed to a device for measuring flow; in particular, to a flow meter having a magnetic pointer.

Meters used to measure fluid flow in engineering or experiments, generally referred to as flow meters, are one of the most important meters in industrial measurement. Depending on the application and the measurement principle, the flowmeter can be divided into volumetric flowmeter, turbine flowmeter, differential pressure flowmeter and area flowmeter. Among them, the area flowmeter is the most widely used. One of the flow meters. The area flowmeter, also known as the float flowmeter, usually consists of a tubular body that expands from the bottom up and a float that can move up and down freely. The measurement principle is to keep the pressure drop constant and use the throttle area. Change to measure the size of the flow. As the fluid flows through the conical tube, the float within the tube is pushed up to a level corresponding to the flow rate. When the flow rate becomes larger, the pressure acting on the float is increased. Since the weight of the float in the fluid is constant, the float will rise and the annulus between the corresponding float and the tapered tube will also increase, thus causing the fluid to flow through the ring. The flow rate of the gap is reduced and the pressure is relatively reduced, allowing the rotor to equilibrate in a new position. By the above principle, the user can determine the instantaneous flow value of the fluid according to the position of the float float.

Area flow meters have the advantages of simple structure and easy testing, and are often used to measure flow in fluids with low flow rates. However, the scale of the conventional flow meter is usually marked on the outside of the transparent cylinder, and when the turbid fluid is encountered, the float cannot be correctly judged. Location, operators often face situations where they cannot easily interpret the correct traffic. Although the electronic flowmeter can measure the flow rate through the sensor to solve the above problem, it also increases the need to set the wire and the power source when the device is installed, thereby increasing the possibility of leakage due to leakage of the fluid, resulting in a problem. Safety and reliability concerns.
