Level Meter

A float level gauge is a liquid level measurement instrument based on the principle of buoyancy. It consists of a float, a float shaft, a float rod, and an indicator. When the liquid level rises or falls, the float will also rise or fall accordingly. Through the linkage of the float shaft and float rod, the scale on the indicator will display the height 1 of the liquid level.

A pressure type liquid level gauge is an instrument that uses liquid static pressure to measure liquid level height. It consists of a liquid level sensor and a pressure transmitter. The liquid level sensor is installed at the bottom of the container. When the liquid level rises, the static pressure of the liquid will also increase. The sensor will convert this pressure signal into an electrical signal, which will be transmitted to the display or control system through a pressure transmitter to achieve liquid level measurement and monitoring.

A radar level gauge is an instrument that uses radar waves to measure the height of liquid levels. It determines the position of the liquid level by emitting radar waves and receiving reflected signals. Radar level gauges have the characteristics of non-contact measurement, high accuracy, and are suitable for various liquids and solid powders. It is suitable for liquid level measurement in high temperature, high pressure, corrosive liquids, as well as flammable and explosive environments.

A capacitive level gauge is an instrument that uses changes in capacitance to measure liquid level height. It consists of a capacitive sensor and a capacitive transmitter. The capacitive sensor is installed inside the container. When the liquid level rises, the capacitance value between the liquid and the capacitive sensor changes. The sensor converts this change into an electrical signal, which is transmitted to the display or control system through a capacitive transmitter, thereby achieving liquid level measurement and monitoring.

The magnetic flap level gauge, also known as the magnetic flap column level gauge, is a float with a magnet (referred to as a magnetic float) designed and produced based on buoyancy and magnetic principles. The position of the measured medium is affected by buoyancy. The change in liquid level leads to a change in the position of the magnetic float, and the coupling effect of static and magnetic forces between the magnetic float and the magnetic flip column (also known as the magnetic flip plate) causes the magnetic flip column to flip at a certain angle (coated with different colors on the surface of the magnetic flip column), thereby reflecting the liquid level inside the container.

The main principle is that the structure of the magnetic levitation ball level gauge (level switch) is mainly designed and produced based on the principles of buoyancy and static magnetic field. The position of the magnetic float in the measured medium is affected by buoyancy: changes in liquid level cause changes in the position of the magnetic float. The magnet and sensor (magnetic spring switch) in the floating ball act to change the number of components (such as fixed resistors) connected in series into the circuit, thereby changing the electrical quantity of the instrument circuit system. That is to say, the change in the position of the magnetic float causes a change in the electrical quantity.

Explosion proof float level switch, also known as explosion-proof float level controller. A liquid level control instrument specially designed and manufactured for use in explosive environments. This product is designed based on the principles of buoyancy and leverage. When the liquid level in the container changes, the position of the float will change with the change in liquid level. The displacement of the float will act on the micro switch through the lever, and the micro switch will generate a switch signal 3.

Working principle and structure The needle valves at both ends of the level gauge not only serve as shut-off valves, but also have the function of check valves with steel balls inside. When the level gauge is accidentally damaged or leaked, the steel balls can automatically close the liquid channel under the pressure of the medium, preventing a large amount of liquid from flowing out and providing safety maintenance. Changing the information of the parts or adding some auxiliary components of the liquid level gauge can achieve functions such as corrosion prevention, insulation, frost prevention, and lighting.

The level gauge is a liquid passage composed of glass tubes designed based on the principle of connectors. The passage is connected to the tested container through a flange or tapered pipe thread, forming a connector. The liquid level is observed through the glass tube to be the same as the liquid level inside the container, that is, the liquid level height. The liquid level gauge can achieve the function of anti-corrosion or insulation by changing the information of the parts or adding some auxiliary components.

Working principle: Steel strip level gauge is a traditional level gauge. A device designed and manufactured using the principle of mechanical equilibrium, consisting of a liquid level detection device, a high-precision displacement transmission system, a constant force device, a display device, a transmitter device, and other peripherals.
