Depth analysis of the blind zone in the use of magnetic field meter

   The application industry and place of the magnetic field meter is much more, such as industrial, chemical, electric power, metallurgy, shipbuilding, construction, environmental protection, food, oil and other environment can be seen as a magnetic level gauge device for measuring the liquid level, in the process of using the magnetic liquid level meter advantage how many users, understand?

 
    Liquid level measurement and control in the production process of magnetic turnover level gauge can achieve high sealing and leakage prevention, and measure liquid medium safely and reliably under high temperature, high pressure, high viscosity, strong corrosive and flammable and explosive conditions. The whole process measurement has no blind area, high sensitivity, display eye, reading intuitionistic, visual measurement is also very considerable. The measurement is accurate and the range of measurement is large. Magnetic level gauge instructions, with a liquid level alarm transmitter, control switch, the upper and lower level implementation or the position of the alarm and control interface signal into standard signal wire 4~20mADC, remote signal, remote detection, indication, record and control, can complete machine can.
    The magnetic turnover level meter is a magnetic floating sensor as a sensing element. It also reflects the measured liquid level or the interface measuring instrument through the magnetic coupling between magnetic float and the magnetic body in the display color column.

    Many users will say that there will be a blind area. Today, how to solve the problem when the magnetic field meter is entered into the blind area?
    Magnetic level gauge is the so-called blind range and the distance between the two flanges, which is on the flange to the tank top and lower flange to tank low this distance, users know the distance if it does not exist blind, solution: when the calculated plan on it. The structure of the equipment this is because the working principle of the magnetic level gauge in the first. It is necessary to have their own float length, even small short also has the corresponding length, so when the liquid level is zero or close to zero, in order to achieve accurate measurement, so the float must be measured to go up the zero level, so it is necessary to consider the blind to zero below the level of the float length. When the container liquid level meter is full, the bottom end of the float must be in full level above. This explains why the magnetic level gauge has the blind spot, this The distance of the blind area is fixed, and the way of calculating the level of the liquid level is different in the following two cases.
  1, the space below the bottom of the tank is enough to meet some distance in the blind area. Then the distance between the two flanges is divided into the full liquid level distance, i.e. the blind area is not considered.
  2, suppose that the bottom space of the tank body is enough to meet some distance in the blind area. When the plan is selected, the time of the flange equipment must be between the bottom and the top part of the tank. When we calculate the liquid level, we should consider the blind area.
  Magnetic level gauge is based on similar products at home and abroad to improve digestion and in accordance with the magnetic level gauge standard promulgated by the former       Ministry of chemical industry development and production of HG/T21584-95 products. The instrument can be used for measuring the medium level of various towers, tanks, grooves, spherical vessels and boilers and other equipment. The body tube of the magnetic turnover gauge is seamless steel tube, and the connecting pipe is welded by the pull hole, and there is no scratch inside. The magnetic flip plate level gauge device can choose side mounted and top mounted. The magnetic flip level gauge is sealed at the lower end of the body, and its indicating function is no other power supply. It is an ideal liquid level detector.
