Talking about the Application of External Measurement Liquid Level Meter in Oil Tank

Oil tanks are storage equipment commonly used in oil refineries, oil depots, oil terminals and petrochemical enterprises. For tank liquid media (petrochemical products), the liquid level, temperature, density and pressure are mainly measured. Parameters such as pressure Storage Tanks are used to calculate the volume and mass storage of the stock solution. Oil tanks are generally divided into two categories: intermediate tanks and trade tanks. The intermediate tanks only monitor parameters such as liquid level, temperature and pressure (with pressure storage tanks) to prevent accidents such as roof collapse and vacuuming of the tanks. Handover monitoring and measurement; the liquid level, temperature, density, volume and quality of the medium in the trade tank must be monitored and measured frequently, and the precision is very high.

The function of the level gauge has the characteristics of clear on-site indication and remote control, so it is widely used in liquid level indications on various towers, tanks, tanks and spherical containers in the petrochemical, fertilizer, pharmaceutical, marine, military and other industries. . At present, the measurement design of the tank level of the oil tank used in the oil tank is more popular. The external measuring level gauge, the magnetic flap level gauge, the steel belt level gauge or the float ball, the buoy, the radar level gauge and the like are popular. It is troublesome to install and maintain the liquid level gauges such as buoys and floats. However, although the radar level gauge has high precision and high cost, the differential pressure level gauge is widely used in closed containers such as boiler steam drums, but the measurement result is not true liquid level, so it is widely used in the design of tank level measurement. less. Dinghua electronic sonar external measuring liquid level meter adopts the principle of sonar echo distance measurement. It does not open the hole, does not move the fire, does not clear the can, and does not stop production. It is the preferred method for measuring the liquid level of the Storage Tank, and it is also the replacement of the technical change. Excellent solution.

Dinghua Electronics' sonar external measuring liquid level meter has been successfully applied to many petrochemical manufacturers. The ELL-FI external measuring liquid level meter has the following characteristics:

1. Directly measure the liquid level in the tank instead of indirectly through the connected device.

Second, the liquid level gauge is easy to install and safe to use. Since the instrument is installed outside the tank body, it is not necessary to damage the tank structure, and it is not necessary to open the hole in the tank body, and the installation does not need to move fire, but the liquid level measuring head is adsorbed on the outer wall of the tank.

3. The sonar external measuring liquid level gauge is a completely non-contact measuring instrument, which does not contact the measured medium, avoids the corrosion of the measured medium to the meter, and also ensures that the medium does not appear to “run and leak”. It will not pollute the environment.

Fourth, the instrument has an automatic calibration function, which can automatically realize the calibration of the instrument and avoid the measurement error caused by the liquid component and temperature change, so the debugging is convenient and the applicability is wide.

5. The instrument achieves Exd IIC T6Gb explosion-proof and IP65/IP67 protection grade, so it can be safely used on liquefied gas tanks. Since the ELL-FI external measuring liquid level meter is all digital, no strong electricity is used, and there is no mechanical friction movement of the meter. Therefore, the meter technology is reliable and can work stably for a long time. The meter is a live digital display, which simulates 4 to 20 mA standard signal output and is convenient to interface with DCS.

Since the ELL-FI external measuring liquid level meter produced by Xi'an Dinghua Electronics Co., Ltd. has been applied to the measurement of the liquid level of the liquefied petroleum gas storage tank, the instrument has been running well. It is easy to install, does not affect production, solves the problem of large measurement error, and is a true non-contact measuring instrument. Since 2000, Dinghua Electronics has launched the ELL series external measuring liquid level meter for 18 years. With the continuous upgrading of products, the ELL external measuring liquid level meter has reached a high level. The external measuring liquid level gauge has lower and lower requirements for the working condition of liquid level measurement, and the applicable surface is more and more wide. At the same time, it has received more and more attention in many industries or departments such as petroleum, petrochemical, chemical and military.
