Product description
JS-201/UHZ series magnetic flap liquid level gauge is a product developed and produced according to the magnetic level gauge standard HG/T21584-95 promulgated by the former Ministry of Chemical Industry. It can be used for medium level measurement of various towers, tanks, tanks, spherical vessels and boilers. The magnetic flap liquid level gauge series can achieve high sealing, anti-leakage and adapt to the liquid level measurement under high pressure, high temperature and corrosive conditions. There is no blind spot in the whole process measurement, the display is eye-catching, and the reading is intuitive. Especially the on-site indication part, because it is not in direct contact with the liquid medium, it can show its superiority for high temperature, high pressure, high viscosity, toxic, harmful and strong corrosive medium. Therefore, it has higher reliability, safety, advancement and practicability than the traditional glass tube type and plate type liquid level gauge.
The most notable feature of the liquid level gauge is that the liquid medium is completely isolated from the indicator, so it is very safe and durable in any situation, and various types of liquid level gauges are equipped with liquid level alarms and control switches. The upper and lower limit offside alarm control or interlock of liquid level or boundary level; equipped with a reed chip set liquid level transmitter, the liquid level and boundary level signals can be converted into two-wire 4-20mADC standard signals, and transmitted to the computer, Regulators and liquid level indicators can realize long-distance indication, detection, recording and control. This series of liquid level meters are widely used in: liquid level measurement in various production processes such as petroleum, chemical industry, metallurgy, pharmaceuticals, food, and electricity. with control.

Principle and Structure
1. Working principle:
⑴The working principle of the magnetic level gauge is based on Archimedes' law, using the principle that the weight of the float is equal to the weight of the volume of the liquid displaced by the float to install The float with permanent magnetic steel changes with the change of the liquid level. The position of the magnetic field line in the float (that is, the actual liquid level position) drives the turning column and the turning plate through the magnetic action. When the liquid level rises, the liquid phase turns red; When the surface falls, the gas phase turns white or black. Thus, the change of the liquid level in the container is clearly indicated.
⑵The display panel is equipped with a ruler, so that the liquid level height can be directly read, and a valve is installed at the lower end of the body for sampling and sewage.
2. Main structure:
⑴ (ordinary type), it is composed of body, float, panel frame and other components. The liquid level gauge is connected with the upper and lower flanges of the container. When connecting, a valve is added in the middle and installed on one side. It is suitable for occasions where insulation or cooling is not required and the medium does not corrode austenitic stainless steel.
⑵ (insulation type), its structure is based on type (1), with the addition of insulation spacers, insulation connection pipes, upper and lower insulation connection pipes to connect with the equipment insulation system, which can be achieved by opening the size of the valve. required temperature.
⑶ (side top type), it is composed of magnetic floating ball, buoy, side body assembly, panel frame and other components, the display position is the top of the side, suitable for high temperature, high viscosity medium or side opening container .
⑷ (top-mounted type), it is composed of panel frame, top-mounted body assembly, guide tube, floating ball and other components. When there is little movement.
⑸ (Vacuum-pumping type), its structure adds a vacuum tube on the basis of type (1) to isolate the level gauge body from the outside world, and is suitable for heat preservation, heating, heat insulation, cooling and other occasions.
⑹ (Teflon-lined type), its structure is lined with polytetrafluoroethylene on the basis of type (1), which is suitable for corrosion-resistant occasions at room temperature and pressure.

Features
Compared with ordinary glass tube type and glass plate type liquid level gauges, it has the following characteristics: ⑴ The material of the main part (body) of the liquid level gauge in direct contact with the medium is made of stainless steel or other special materials, and the indicating parts are not in contact with the medium. Therefore, it is very safe and reliable to use the level gauge for containers containing flammable, explosive, toxic and corrosive media.
⑵Double-color (gas phase is white, liquid phase is red) flip-up column and flip-board display, the indication is continuous, intuitive and eye-catching, no blind area, and no false liquid level will appear under any circumstances.
⑶ With less sealing surface, the static seal leakage point is reduced by more than 95% compared with the original plate level gauge. Therefore, it overcomes the weak links such as running, running, dripping and leaking of pressure vessel accessories in the petroleum and chemical industries.
⑷Simple structure, convenient installation and maintenance, large measuring range, high design pressure, long service life and wide application range.
