Magnetic sensitive electronic two-color liquid level meter

The magnetic-sensitive electronic two-color liquid level meter uses a conductor light-emitting device, which has high brightness, a red and green two-color display, a long visual distance, a clearer scale, a larger display range, and a more serialized product, especially in iron and steel enterprises with large environmental smoke and dust and containing fine iron filings. , if a magnetic flap liquid level meter is used, due to the magnetic adsorption effect, fine iron filings will cover the red and green colors of the magnetic flap, making it impossible to observe the liquid level. However, the magnetic sensitive electronic two-color liquid level meter can effectively solve this problem. Magnetic sensitive electronic two-color liquid level gauge is widely used in the liquid level measurement and control of various tower tank boiler equipment in the production process of various industries such as power, metallurgy, petrochemical industry, environmental protection, shipbuilding, etc. It is made of high-quality stainless steel and imported electronic components. The display part uses high-brightness two-color light-emitting tubes to form a columnar display. Through the red and green changes of the light column, the upper and lower limit alarms and control of the liquid level can be realized. The optional liquid level transmitter can control the liquid level. The bit signal is converted into an analog error signal, which can realize remote detection, indication recording and control, and also directly communicate with the computer system.
Working principle
There is a magnetic float in the main conduit of the liquid level meter. The float is designed according to the specific gravity of the medium. The magnetic steel in the float is at the same height as the liquid level in the container. The liquid level display scale is equipped with a semiconductor magnetic sensor. And the light-emitting module is arranged in an orderly manner up and down. The semiconductor magnetic sensor corresponding to the magnetic field is magnetized and triggers the corresponding digital circuit. It displays red above the liquid level, green below the liquid level, red displays the vapor phase, green displays the liquid phase, and red The green junction is the actual liquid level in the container, the liquid is green and the vapor is red, which is clear at a glance.
Product Features
Red liquid green, clear luminous display, large viewing angle and long viewing distance. It can clearly display the liquid level with red and green light beams. It is suitable for use in dark places and is more eye-catching for nighttime observation.
The body is made of stainless steel. The liquid level gauge display device does not come into contact with the medium in the container and there is no leakage. It is suitable for use in Class 1, 2 and 3 containers and is absolutely safe and reliable for containers containing flammable, toxic and corrosive media.
It has a large display range and a wide range of applications, and is suitable for low, medium and high-pressure situations.
Output ~ standard signal to realize remote display of liquid level, centralized monitoring and control of liquid level in container groups, and can also be equipped with liquid level switch to realize chain protection.

Installation and use of magnetically sensitive electronic two-color liquid level gauge
How to use this hydraulic gauge Connect the flange and the sealing gasket on the container flange clamp, and tighten the bolts.
Open the sensor drain flange and insert the float. Note that the magnetic steel end of the float is facing upward and cannot be turned upside down.
Install a valve under the sensor drain flange and connect it to the original liquid level meter drain pipe.
Connect the power supply, input power or plug in the power supply to adjust the level gauge to a position convenient for observation.
Open the upper valve first, and then slowly open the lower valve, especially when used in high-pressure situations, and slowly inject pressure so that the medium slowly flows into the sensor to prevent the float from being damaged by sudden pressure. Observe the liquid level display. , changing from red to green one by one.
Observe whether the water level display of the sewage and water supply high and low alarms is normal. If there is no abnormality, it can be put into use.
