How to use and work principle of float level controller

Abstract: The information on the use method and working principle of the float level controller is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. How to use the float level controller 1. Pass the cable of the float switch through the central hole of the weight, and push the weight gently to the desired range of liquid level control. The longer the cable between the weight and the float, the greater the height difference in controlling the liquid level. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the use method and working principle of the float level controller. How to use the float level controller 1. Pass the cable of the float switch through the central hole of the heavy hammer, and gently push the heavy hammer to the range that needs to be set for liquid level control. The longer the cable between the weight and the float, the greater the height difference of the control liquid level; 2. The weight of the float level controller should be fastened with the matching plastic ring. In order to prevent the weight from sliding and affecting the control of the liquid level. It is best to use a copper wire to tie the upper and lower ends; 3. Pull the cable directly to the control box, and avoid joints in the middle. If there are joints as a last resort, never immerse the joints in liquid; Wire ends should be wrapped with insulating tape. The float level controller is suitable for automatic control or alarm of water in water towers, water tanks, pools, etc. in industrial and mining enterprises, civil buildings, and scientific and technological research fields. At the same time, it can also be widely used in environmental protection“Three wastes”In facilities that treat sewage and discharge liquids. It has the advantages of simple structure, convenient installation and maintenance, accurate and reliable action, and is not affected by water level fluctuations. The float level controller uses the JAG-5 high-power dry reed switch (hereinafter referred to as the dry reed switch) as the main control element, which is installed in the guide tube; the float ball is sleeved outside the guide tube, and the ball is equipped with a circular permanent magnetic steel ;The upper part of the conduit is provided with a sealed junction box with wiring terminals inside, and the bottom of the conduit is sealed with a threaded bottom sleeve. The conduit of the controller is installed vertically in open containers such as water towers, water tanks, and pools, and the floating ball moves up and down as the water level changes. Lifting, when the water level drops to the controlled low water level (or rises to the controlled high water level), the reed switch is subjected to the action of the magnetic field to overcome the reed restoring torque, the reed action normally open contact is closed, and the normally closed contact is disconnected) , send out a low water level signal, and act on the water level automatic control device or water level alarm device. Measurement principle of float level gauge The float level gauge consists of a float ball, a plunger and the like. The floating ball level gauge is installed on the top of the container through the connecting flange. The floating ball floats on the liquid surface according to the principle of equal volume of the discharged liquid. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the floating ball floats. The dry reed of the ball level gauge is magnetically attracted to change the position of the liquid level into an electrical signal, and the actual position of the liquid is displayed digitally through the display instrument, so that the float level gauge can achieve long-distance detection and control of the liquid level. Introduction The magnetic float level gauge is mainly composed of three parts: the magnetic float ball, the sensor and the transmitter. When the magnetic float ball changes with the liquid level and floats up and down along the conduit, the magnetic steel in the float ball pulls in the reed switch at the corresponding position in the sensor, so that the total resistance (or voltage) of the sensor changes, and then the sensor is transferred by the transmitter. The changed resistance (or voltage) signal is converted into a 4-20mA current signal output, and the UQK series digital display controller (or DSB type light column digital display device) provided by Shanghai Automation Instrument No. 5 Factory can be used to remotely monitor the liquid level. Distance measurement, and the upper and lower limit alarms can be set on the display instrument to realize the position control of the liquid level, or a constant liquid level adjustment system is formed by other regulators to realize the PID continuous adjustment of the liquid level. Application field The float level gauge has the characteristics of simple structure, convenient debugging, good reliability and high precision. The float level gauge can be widely used in the continuous measurement of the liquid level (interface) of high temperature, high pressure, viscous, dirty media, asphalt, wax-containing oil products, and flammable, explosive, corrosive and other media. The float level gauge can be used for industrial level measurement and control of various liquid tanks such as petroleum, chemical raw material storage, industrial process, biochemical, pharmaceutical, food and beverage, tank farm management and gas station underground storage. The float level gauge is also suitable for dam water level, reservoir water level monitoring and sewage treatment, etc. The above is the whole content of this article.
