Overview of Heavy Oil Level Gauge ProductsPrice of heavy oil level gauge
The heavy oil level gauge is a product developed and produced by our company by introducing and absorbing similar foreign products, and absorbing, digesting, and improving them according to the magnetic level gauge standard T21584-95 issued by the former Ministry of Chemical Industry. It can be used for medium level detection of various towers, tanks, spherical containers, boilers and other equipment. This series of magnetic level gauges can achieve high sealing, leak prevention, and adapt to liquid level measurement under high pressure, high temperature, and corrosive conditions, with reliable safety. It makes up for the shortcomings of glass plate (tube) level gauges, such as unclear indication and easy breakage, and is not affected by high and low temperature fluctuations, without the need for multiple sets of level gauge combinations. The entire measurement process has no blind spots, with clear display, intuitive readings, and a large measurement range. Especially for the on-site instructions, as they do not come into direct contact with liquid media, they are more effective against high temperature, high pressure, high viscosity, toxic and harmful, and highly corrosive media. Therefore, it has higher reliability, safety, reliability, and practicality than traditional glass tubes and plate level gauges. The digital signal processing technology used in the heavy oil level gauge avoids the influence of container wall thickness and achieves true non-contact measurement of the liquid level height inside the sealed container outside the tank. The sonar sensor (probe) is installed directly below the outer wall (bottom) of the tested container, without the need to open holes in the tested container. It is easy to install, enables online installation and debugging, and does not affect production. It can measure the liquid level of various flammable, explosive, toxic and other hazardous media, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure sealed containers.

The significant feature of heavy oil level gauges is the isolation between the liquid medium and the indicator, making them very safe, reliable, and durable in any situation. Moreover, various models of level gauges are equipped with level alarms and control switches, which can achieve upper and lower limit over limit alarms, control, or interlocking of the level or boundary; Equipped with a static pressure level transmitter or a dry spring resistance level transmitter, the liquid level and boundary signals can be converted into a two-wire 4-20mADC standard signal, enabling remote indication, detection, recording, and control. Suitable for liquid level measurement in corrosive media and high operating temperatures, with reliable structure and long service life. It is the best choice for measuring the liquid level of highly corrosive media such as nitric acid. Tailored for customers with low temperature and pressure requirements, our PP material level gauge can be used. This series of heavy oil level gauges can be widely used for level measurement and control in various industries such as power, petroleum, chemical metallurgy, environmental protection, shipbuilding, construction, and food production processes.

Users can use remote transmitters according to engineering needs, which can achieve local digital display and output standard remote transmission electrical signals of 4-20mA to meet the needs of recording instruments or industrial process control. It can also be used in conjunction with magnetic control switches or proximity switches to monitor liquid level alarms or control inlet and outlet equipment.

Working principle of heavy oil level gauge

The heavy oil level gauge adopts the principle of sonar ranging, using a probe attached to the outside of the container wall to collect sonar signals. With sonar wave processing technology as the system core and high-speed signal processing technology of *, the algorithm of Shaanxi Acoustic Science is used to calculate the liquid level inside the container. The calculated liquid level value is displayed locally and outputs a remote transmission signal. The instrument can output measurement results to the control center through (4-20) mA analog signals, HART, RS-485 and other interfaces, and can also be debugged online through HART, RS-485, infrared and other interfaces.

Correct assembly, use and maintenance of heavy oil level gauge

1. Magnetic substances are not allowed to approach the body of the heavy oil level gauge, and iron wire fixation is prohibited, otherwise it will affect the normal operation of the heavy oil level gauge;

2. When users use heat tracing pipelines themselves, non-magnetic materials such as copper pipes must be selected. The heat tracing temperature is determined based on the condition of the medium;

3. The installation of heavy oil level gauge must be vertical, and a ball valve should be installed between the heavy oil level gauge and the container inlet pipe for easy maintenance and cleaning;

4. The medium should not contain solid impurities or magnetic substances to avoid jamming the float;

5. Before use, use a calibrated magnetic steel to place the small balls below zero position in red and the other balls in white;

6. Open the bottom flange and install the magnetic float (note: the heavy end with the magnetic end is facing upwards and cannot be inverted);

8. According to the condition of the medium, the main pipe should be cleaned irregularly to remove impurities;

9. For level gauges that exceed a certain length (ordinary type>3 meters, anti-corrosion type>2 meters), it is necessary to add a middle reinforcement flange or ear hook as a fixed support to increase strength and overcome its own weight;

10. The installation position of the heavy oil level gauge should avoid or be far away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid, which may affect the accuracy of the level measurement;

11. When equipped with remote transmission instruments, the following measures should be taken:

(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 connection between 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.
