The ultrasonic level gauge is externally attached to the surface of the object to be measured. It can be used for the measurement of dangerous goods such as gas tanks and oil tanks to avoid danger. The next editor will explain the technical features of the external ultrasonic level gauge.1. What is the purpose of the external ultrasonic level gauge?Liquid level and liquid level measurement are common problems in the industry. Ultrasonic positioning technology has many advantages. It can not only provide fixed-point and continuous positioning, but also easily provide signals required for telemetry and remote operation. Compared with radioactive positioning technology, ultrasonic technology does not require protection. Compared with laser ranging technology, it has the advantages of simplicity and economy. At the same time, ultrasonic technology generally does not require moving parts, so I think the Mianter is easy to install and maintain. Ultrasonic level gauges can be widely used in petroleum, mining, power plants, chemical plants, water treatment plants, sewage treatment plants, agricultural water, environmental protection monitoring, food (wine industry, beverage industry, additives, edible oil, dairy products), flood control , Hydrological monitoring, open channels, spatial positioning and many other industries.External ultrasonic level gauge2. What are the technical characteristics of the external ultrasonic level gauge?1. Transducer with strong emission power, the surface can be self-cleaned, and the new transducer structure and manufacturing technology are used to significantly improve the working performance of the transducer.2. Microprocessor program control, intelligent signal processing technology, realize a variety of typical software processing modes, so that the level gauge can adapt to complex conditions such as solids, liquids, and dust.3. Use the infrared remote control to adjust the program, the operation is simple and reliable, and it is equipped with LCD on-site display.4. Reduce non-contact continuous measurement and maintenance;5. It can be used for the measurement of level, space and distance, and can also carry out automatic level-volume conversion for standard or special switch liquid tanks; 6. LCD with backlight can display in standard engineering units.3. What are the solutions to the problems in the measurement of the ultrasonic level gauge?Question 1. The instantaneous value of the ultrasonic level gauge fluctuates greatlyThe large fluctuation of the instantaneous value indicates the large fluctuation of the signal strength of the ultrasonic level gauge and the large fluctuation of its own measurement value.Solution: Adjust the probe position to increase the signal strength to ensure the signal strength is stable. When the value of itself fluctuates greatly, it is recommended to re-select the installation location.Common problem 2. After power on, the meter only has backlight and no text displayExternal ultrasonic level gaugeFrequently Asked Questions 3. The transmitter value of the ultrasonic level gauge fluctuates greatlyThis problem usually occurs in three situations: the sensor’s bell mouth is frozen, suspended objects may interfere, and electromagnetic fields may interfere with the environment.Treatment method: It is recommended to install the instrument away from the frequency converter, variable frequency motor, high-power electric equipment and strong magnetic field interference, and have a good ground wire; when it is unable to leave, please install a metal instrument box on the outside of the ultrasonic level gauge. Cut off the shield, and the instrument box is also grounded. The editor thinks that it is very convenient to measure the measured value with an external ultrasonic level gauge, and the measurement operation is relatively simple and easy to use, but it is necessary to pay attention to the magnetic field interference of the environment.
