Gas station level gauge can completely replace the traditional measurement methods, intelligent, high efficiency, high precision, good stability, compared to many current gas station tank oil measurement using artificial climbing can also vote for measuring. Measured with a metric steel tape measure or graduated scale with a hammer, this method of measurement is not only labor intensive but with insecurity and accuracy. Is there a high-precision, stable and reliable, low failure rate, capable of intelligent measurement of oil equipment? The answer is: yes, and we've done it already. That is to use the principle of magnetostriction, self-developed design and production of SYW series magnetostrictive level gauge, gas station liquid level instrument replacement of the best products.
From simple liquid level measurement and inventory management to the automatic management of oil products in the entire gas station, centralized management and optimized distribution of the oil products of the Group users, Qingdao Guihe Measurement and Control Technology Co., Ltd. can provide different liquid level measurement The solution. In response to the status quo and development requirements of backstage management equipment in domestic gas stations, the level gauge console is compatible with the mainstream gas station back-end management system and retains enough room for upgrading. GUIHE products are widely used in gas stations that require high reliability, high stability and high precision.
Gas station liquid level measurement and oil-water interface measurement can be measured simultaneously using a magnetostrictive liquid level gauge, which is currently the best liquid level interface measurement and control technology. Magnetostrictive level gauge can provide two independent output: First, the interface; Second, the overall level. Can be applied to the smallest proportion of 0.02S.G. Commonly used in oil-water interface measurement.
Gas stations into the oil when we need to monitor the amount of oil to prevent overflow during oil delivery, once beyond the dangerous level, the liquid level gauge will trigger an automatic alarm function, the most common way is to use the sound Light alarm prompts managers to stop oil. So how is this achieved?
First: gas station level gauge has a high level alarm function, when the oil level rose to the required position, it will trigger the alarm sound, remind staff to stop oiling in time to avoid oil spills without knowledge. It is very convenient to install this liquid level gauge in the oil tank, and the reliability is very high and the precision is not bad, so as to reduce the accident rate, it can play a multiplier effect.
Second: There is another situation is the gas station tank will leak, unconsciously, forever lost a lot of gasoline and diesel, relative to the loss of the environment is the greatest harm, this is the focus of the environmental protection department Check the link, but also a lot of gas station carefully monitor the installation of liquid level the main reason. Gas station liquid level gauge is often installed in the top of the tank, suitable for gas stations lying tanks, large storage tanks, which itself comes with anti-seepage function, this is how to achieve it?
Gas station level meter background software has such a function: the level gauge display interface to set the corresponding tank for a period of time, and then set a value consistent with the safety monitoring bureau leakage, and then run, if the result Greater than the default volume then the tank is the possibility of leakage, it must be maintained or replaced, there will be sound and light alarm prompt staff results data, it can be said that gas station managers a good helper.
Third: In fact, the liquid level gauge will make accurate statistics on the volume of the tank as a whole, and set an accurate numerical value at a safe oil level. If the oil level exceeds this pre-alarm value during the filling process, the liquid level gauge Probe float will exceed the predetermined height, it will send information to the liquid level monitor, so that staff promptly found, while the sound and light alarm action, alarm, remind staff immediately stop the oil, to avoid oil Overfilling cans cause dangerous and economic losses.
Fourth: the other case is when the oil tank below the predetermined value when the automatic alarm function will also be action to remind staff need to replenish the oil, so that the virtuous cycle of the petrol station, the specific principle here no longer More statements.
Fifth: there is another situation will trigger the automatic alarm function, when the bottom of the tank above the water level, there will be automatic alarm level gauge to remind staff need to drain the bottom of the tank, lowering the water level, raising the tank Oil storage capacity.

A: high precision
Since the magnetostrictive liquid level gauge determines the amount of displacement to be measured by measuring the time difference between the transmitted pulse and the return pulse, the measurement accuracy is extremely high. Its nonlinearity is less than 0.05% FS, repeatability is less than 0.001% FS, resolution is less than 0.002% FS. Such high measurement accuracy is unique in today's level measurement, and other types of sensors are difficult to achieve with this accuracy.
B: Multi-parameter measurement
Magnetostrictive liquid level gauge another big feature is the set of measurement of liquid level, interface, temperature and other parameters in one. Because magnetostrictive level
The electronic components in the gauge can detect continuous magnetic waves generated by the same emission pulse, so two or more magnetic floats can be equipped on the same probe rod. As long as the float weight and media to ensure that the corresponding weight, you can simultaneously measure the liquid and the interface, the real multi-parameter measurement.
If multiple temperature sensors buried in the magnetostrictive level gauge sensor rod, then the liquid level can be measured at the same time can get media
Multi-point temperature and the average temperature below the surface.
C: high safety
Magnetostrictive level gauge explosion-proof level generally have two kinds of flameproof and intrinsically safe, suitable for a variety of flammable, explosive, high temperature, high pressure
And other dangerous places to use. And the use of magnetostrictive liquid level gauge without manually opening the lid, to avoid the artificial measurement brought
Security risks.
D: high reliability, low failure rate, long life
Since the entire transmitter of the magnetostrictive level gauge is sealed in a stainless steel tube, the sensing element is not in contact with the measured medium, so
Although the measurement process is repeated, it does not cause any wear on the sensor. Therefore, it has the advantages of high reliability, low failure, long life, suitable for a variety of harsh environments.
E: easy to install and maintain
Magnetostrictive liquid level gauge with flange connection, to help install the most convenient, and no need to maintain or re-calibration
, To bring great convenience to the user.
F: easy to automate management
Magnetostrictive liquid level gauge general output signal interface using 4 ~ 20mA standard current signal or RS-485 digital signal interface, direct access to PLC, DCS systems or other computer management systems for easy computer signal processing.
