The float level gauge consists of four basic parts: buoy, spring, magnetic steel chamber and indicator. A buoy submerged in a liquid is subjected to a combination of downward gravity, upward buoyancy, and spring forces. When these three forces reach equilibrium, the buoy will rest in a certain position.
The structure of the float level gauge is mainly designed and manufactured according to the principle of buoyancy and static magnetic field. The position of the floating ball with magnet in the measured medium is affected by buoyancy, and the change of liquid level leads to the change of the position of the magnetic float. The function of the magnet and sensor (reed switch) in the floating ball is to change the number of components (such as fixed resistance) in series in the circuit, thus changing the power of the instrument circuit system. That is, the change of the position of the magnetic float causes the change of the electric quantity. The liquid level in the container is reflected by measuring the change in the amount of electricity.
The float level gauge consists of four basic parts: buoy, spring, magnetic steel chamber and indicator. A buoy submerged in a liquid is subjected to a combination of downward gravity, upward buoyancy, and spring forces. When these three forces reach equilibrium, the buoy will rest in a certain position. When the liquid level changes, the buoyancy of the buoy changes accordingly, and the equilibrium state is broken, which causes the elastic force to change, that is, the expansion and contraction of the spring, reaching a new balance. The expansion and contraction of the spring causes it to move with the rigid magnet. Therefore, the liquid level can be indicated by the magnetic induction element and the transmission device in the indicator.
Features and Applications of 2. Float Level Gauge and Float Level Gauge
The float level gauge can be used for liquid level measurement and control in almost all kinds of industrial automation process control, and is widely used in petroleum processing, food processing, chemical industry, water treatment, pharmaceutical, electric power, papermaking, metallurgy, shipbuilding and boilers. The reason why the float level meter is widely used is inseparable from its following characteristics:
(1) The product has stable performance and long service life.
(2) Simple structure, convenient installation, use and maintenance.
2. Float level gauge
The float level gauge has the characteristics of intuitive display, stable operation and high measurement reliability. In addition to measuring the liquid level of high viscosity medium, it is suitable for the liquid level measurement of important containers and equipment in the continuous production of refining and chemical industry, such as tower, storage tank intermediate container, etc.
Its product features are as follows:
(1) Stable and reliable work, high measurement accuracy and sensitivity.
(2) The measuring range is large, and the measuring range can reach 3000mm.
(3) High temperature resistance, high pressure and strong corrosion resistance.
(4) can be on-site instructions or remote measurement.
(5) On-site debugging is convenient, easy to check and maintain.
2. Characteristics of float level gauge
(1) No output or low output: check the line voltage; Whether there is a short circuit or multi-point grounding; Check the polarity of the signal line; Check the loop resistance; Check the range; Circuit board failure; The stolen goods are accumulated inside the float.
(2) The output is unstable: check the line voltage, whether there is an intermittent short circuit, open circuit or multi-point grounding; whether the circuit board is faulty.
(3) High output: Check whether the process variable is out of range; Check the terminals, pins or sockets, check the power supply voltage, and whether the electronic circuit components are faulty.
