Liquid bromine level gauge

Liquid brominelevel gaugeThe high and low level alarm level gauge uses a float as the measuring element and a magnetic steel driven flip column display, without the need for energy. Users can install a controller on the main pipeline of the liquid level gauge at the upper and lower limit positions set by the user. The controller is equipped with a self holding reed switch, which uses a magnetic float to move with the liquid level to trigger an alarm or limit control when the switch is activated.

The significant feature of this level gauge is the isolation of the liquid medium from the indicator *, so that its measurement can be safely monitored in any situation. At the same time, the magnetic flap level gauge is reliable and durable enough, and can also issue alarms for exceeding the upper and lower limits of the liquid level, providing remote control and recording. It can be used for medium level detection in various equipment such as towers, tanks, spherical containers, and boilers.

Liquid bromineUsage conditions of liquid level gauge:

It is most suitable to use it as a detector for some highly corrosive and toxic substances. In addition, the designed readings are quite intuitive, which makes the magnetic flap level gauge suitable for various liquid level detection tasks.

Liquid level water system:

The raw water used in the water system (raw water system, water production system, desalinated water system) is groundwater and carbonized return water (groundwater used for carbonization cooling), supplied by the water supply and drainage workshop. After entering the siphon filtration tank, it is sent to the collection tank and sent to the desalinated water system by a booster pump for desalination. The main system is a unit type first stage complex bed desalination system, and the cation and anion beds are double chamber boiling floating beds, divided into five sets of systems A, B, C, D, E, each of which can operate independently. For example, the remote magnetic flap level gauge can be connected to the DCS system of the system by outputting the measurement signal in the form of a 4-20mA signal. With the cooperation of other equipment in the system, the level measurement and control can be achieved. The process flow of the water system is shown in Figure 1. The company adopts the Zhejiang Central Control ECS100 DCS control system for control. Each system has an output of 190 t/h. The desalinated water is produced and sent to the desalinated water tank through a desalinated pump. After adding ammonia, it is sent to the steam turbine deoxygenation and chemical system for production use.

Liquid bromineApplication of liquid level gauge in water treatment:

Through the water treatment process diagram and acid-base system diagram, it can be seen that the main equipment for acid-base metering is the cation, anion, and mixed bed ion exchange system, which is based on the research on improving the liquid level measurement method of the acid-base metering tank. Yang, Yin, and mixed beds are the main water treatment equipment. Raw water is treated with cation and anion exchange resins in the Yang, Yin, and mixed beds to produce desalinated water that meets the production needs of boilers and chemical units. Due to the reversibility of cation exchange resin, it can be reused repeatedly. When the resin fails, a certain amount of acid-base regeneration can be used to restore its performance and continue water production. At this point, the amount of acid and alkali used is measured based on the volume of the water production equipment (anion, cation, mixed bed) and the volume of the resin, that is, the liquid level in the measuring tank is limited (with a total of 8 upper and lower limits), to assist in the regeneration process of the equipment. In order to meet the requirements of water production technology and save water production costs, it is necessary to modify the measurement values in a timely manner.

When the magnetic flap remote transmission level gauge is equipped with remote transmission supporting instruments, the following requirements must be met:

(1) The remote transmission supporting instruments should be tightly attached to the main pipe of the liquid level gauge and fixed with stainless steel clamps (iron is prohibited);

(2) The sensing surface on the remote transmission supporting instrument should face and be closely attached to the main tube;

(3) The zero position of the remote transmission supporting instrument should be on the same horizontal line as the zero position indication of the liquid level gauge;

(4) The wiring between the remote transmission supporting instruments and display instruments or industrial control computers should be separately laid in protective tubes or shielded two core cables;

​

(5) After the wiring holes of the junction box are laid, it is required to be well sealed to prevent rainwater, moisture, etc. from entering and causing the remote transmission supporting instruments to not work properly. The junction box should be promptly covered after maintenance or debugging is completed.

Liquid bromineCommon selection of water level gauges in valves:

One type: ball valve
The opening and closing element (ball) is a valve driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control, among which the hard sealed V-shaped ball valve has strong shear force between its V-shaped core and the metal valve seat of the welded hard alloy, especially suitable for media containing fibers, small solid particles, etc. The multi way ball valve on the pipeline can not only flexibly control the merging, splitting, and switching of the flow direction of the medium, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valve classification: pneumatic ball valve, electric ball valve, manual ball valve. Generally, a manual ball valve is sufficient for docking with the flange interface of the side mounted magnetic flap level gauge. He has wear resistance, good sealing performance, light switch force, and long service life. Generally, there are more ball valves connected by flanges
Second type, globe valve
Globe valve, also known as shut-off valve, belongs to the forced sealing type valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the diameter of the valve stem should be larger, otherwise the valve stem bending fault may occur. There are three types of connections: flange connection, threaded connection, and welded connection. At high pressure, the built-in drain valve of the side mounted magnetic flap level gauge will be replaced with a threaded high-pressure drain valve, and a flange connected globe valve will be connected to the flange interface of the tank body. Globe valves have a simpler structure than gate valves, are easier to manufacture and maintain, have higher fluid resistance, and require greater force to open and close, which is not as good as ball valves.

Liquid bromineCommon Table for Selection of Tank Level Gauge:

Working principle of tank level gauge:

It consists of two parts: the on-site indicator section and its auxiliary devices, and users can also choose the on-site indicator section separately. This instrument can be used for medium level detection of various equipment such as 1 tower, 2 tanks, 3 tanks, 4 spherical containers, and boilers. This level gauge can achieve high sealing, leak prevention, and is suitable for applications with 1 high temperature, 2 high pressure, and 3 corrosion resistance. It compensates for the defects of poor clarity and easy breakage of glass plate (tube) level gauges, and the entire measurement process has no blind spots, with clear display and a wide measurement range. Due to the fact that the measurement display does not come into direct contact with the medium, it is more effective against 1 high temperature, 3 high pressure, 3 toxic, 4 harmful, and 5 strong corrosive media. Therefore, it has higher 1 reliability 2 safety 3 practicality 4 than traditional glass plate (tube) level gauges.
