Description
Product introduction:
UHZ magnetic flap liquid level gauge (level transmitter) is a product developed and produced according to the magnetic level gauge standard HG/T21584-95 promulgated by the former Ministry of Chemical Industry according to the similar products at home and abroad. The meter can be used for media level detection in a variety of towers, tanks, tanks, ball vessels and boilers.
The magnetic flap level gauge can be used for medium level detection of various towers, tanks, tanks, ball vessels and boilers. This series of level gauges can be highly sealed, leak proof and suitable for high temperature, high pressure and corrosion resistant applications. It compensates for the defects such as poor definition and easy cracking of the glass plate (tube) level gauge, and the whole process measurement has no blind zone, and the display is clear and the measurement range is large. The parts of the magnetic flap level gauge are made of 1Cr18Ni9Ti, 316L, OCr18Ni9Ti, 1Cr18Ni9Ti-lined PTFE (polytetrafluoroethylene), PVC, PP and other imported components, which have excellent reliability and corrosion resistance.
Working principle:
The magnetic flap level gauge (also known as the magnetic float level gauge) is developed based on the buoyancy principle and magnetic coupling. When the liquid level in the measured container rises and falls, the magnetic float in the body tube of the liquid level gauge also rises and falls, and the permanent magnetic steel in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flipping column to flip 180 °, when the liquid level rises, the column changes from white to red. When the liquid level drops, the column changes from red to white, and the red-white junction of the indicator is the actual height of the liquid level inside the container, thus achieving a clear liquid level. Instructions.
Use:
The magnetic flap level gauge can be used directly to observe the level of the medium in various containers. It is suitable for liquid level indication in petroleum, chemical and other industrial fields. The liquid level gauge has a simple structure, is intuitive and clear to observe, does not block or leak, and is easy to install and simple to maintain. The upper and lower mounting flanges of the glass plate level gauge are connected to the container to form a communicating device, and the actual height of the liquid level in the container can be directly observed through the glass plate. The upper and lower valves are equipped with safety steel balls. When the glass is accidentally damaged, the steel balls are automatically sealed under the action of the internal pressure of the container to prevent the liquid in the container from overflowing and to ensure the safety of the operator.
For more than a certain length, the intermediate reinforcement flange or ear climbing should be added as a fixed support to increase the strength and overcome its own weight; the installation position of the magnetic flap level gauge should be avoided or away from the inlet and outlet of the material medium to avoid materials. The rapid change of the local area of the fluid affects the accuracy of the liquid level measurement; when equipped with the remote transmission supporting instrument, the following items should be implemented: 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; The connection between the remote transmission supporting instrument and the display instrument or the industrial computer is preferably laid by a protective pipe alone or with a shielded two-core cable; the remote supporting instrument should be closely attached to the main pipe of the liquid level gauge and fixed with a stainless steel hoop ( The iron surface is forbidden; the sensing surface on the remote transmission supporting instrument should face and close to the main conduit; after the wiring box inlet hole is laid, the sealing is required to be good, so as to prevent the intrusion of rainwater and moisture, so that the remote supporting instrument can not work normally, the junction box It should be covered in time after the inspection or commissioning is completed.
installation:
The proximity of the magnetizer around the main body is not allowed to directly affect the accurate operation of the liquid level gauge. In order to prevent damage to the float assembly during transportation, the float assembly is taken out of the main body of the liquid level gauge before leaving the factory. After the level gauge is installed, open the bottom drain flange and reload the float assembly into the main body. Inside the tube, note that the heavy part of the float assembly is facing up and cannot be flipped.
Magnetic flap level gauge measurement method and troubleshooting
The top or side tube side mounting method is used to measure the liquid. A magnetic column indicator, a liquid level switch and a liquid level transmitter are added to the main body of the magnetic column. The magnetic unit is placed inside the floating ball or connected to the floating ball through the ejector pin. When the floating ball and the magnetic unit change with the liquid level, the magnetic color block (magnetic flip plate) is turned over; the magnetic liquid level switch operates at the corresponding liquid level point; At the same time, the liquid level sensor outputs a standard change resistance signal under the action of the floating ball magnetic force, and then converts the resistance signal into a 4~20 mA current signal output through the transmitter.
Features:
1. Wide application range and various installation forms, suitable for measuring the liquid level and interface of any medium.
2. The measured medium is completely isolated from the indicating structure, and has good sealing performance, anti-leakage, high-pressure, high-temperature and corrosive liquid level measurement, and high reliability.
3, set on-site indication, remote transmission, alarm control switch in one and freely adjustable, full-featured Two-color indicator with luminous, continuous and intuitive, eye-catching, large measurement range, the observation direction can be arbitrarily changed.
4. It has good vibration resistance and can adapt to the situation of large fluctuation of liquid level. The structure is simple, easy to install and low in maintenance cost.
5, with a beautiful magnetic steel corrector, on-site random adjustment of technical parameters.
