Regarding ultrasonic level gauges

Are there high-power motors and pumps in the area around where the instrument is to be installed? If so, try to place the instrument as far away from these devices as possible and adjust its installation location. Also, check whether temperature issues have caused crystallization at the bottom of the transducer; if crystallization is present, clean it off. It seems that guided-wave radar level gauges are more reliable.

Check whether the installation location is too close to the tank wall or anything similar; a certain distance must be maintained. Additionally, metal flanges or connectors cannot be used for installation. Also, there should be no moisture or anything like that on the probe; go and check it. Which brand of ultrasound is this?

It’s related to the watch; try turning off the power and restarting it. Some devices simply have poor quality

The HCL salt is volatile in acid form; could it be that over time the surface has been corroded?

Which brand of ultrasound is this? J-15 external-mounted ultrasonic level controller (J15D3I). The ultrasonic probe is attached to the outer wall of the container being tested, right below it, and can penetrate container walls made of steel, iron, stainless steel, glass, plastic, or fiberglass up to a thickness of 8 millimeters ； It enables continuous and accurate measurement of the liquid level inside the tank, with no contact at all with the liquid and gas within the tank, thus achieving true isolated measurement. Therefore, it possesses seven advantages that no other level gauge can match: 1. It can be used in the most demanding environments—capable of measuring liquids with any pressure, high toxicity, strong corrosiveness, absolute sterility, or extremely high purity, as long as their sound speed is known. 2. Safety—when measuring liquids that are toxic, corrosive, under pressure, flammable, explosive, volatile, or prone to leakage, since both the sensing element and the instrument are located outside the container, there is no contact with the liquids and gases inside the tank during installation, repair, or maintenance, ensuring high safety. Even when the instrument is damaged or under maintenance, there is absolutely no possibility of leakage. 3. Environmentally friendly – It features true isolation measurement, with no contact at all with the medium being measured; there is no possibility of liquid or gas leakage, and it does not pollute the environment, making it a truly green and environmentally friendly instrument. 4. Convenience and cost-effectiveness — Online maintenance can be carried out without shutting down production. Since there is no need to make holes in the container, nor are flanges or connection pipes required, installation and maintenance are extremely convenient and cost-effective. 5. Durable and reliable—The measuring head and instrument contain no mechanical moving parts, and are tightly sealed to isolate them from the outside environment; as a result, they do not wear out or corrode, making them highly durable and reliable with minimal maintenance required. 6. Precision — The H-15D3I surface-mounted ultrasonic level controller features temperature compensation and continuous automatic calibration, ensuring the highest measurement accuracy at all times. The precision is 1 millimeter, with a maximum range of 3 meters. It can be used properly and provide accurate measurements even in different temperatures as well as on moving vehicles and ships. 7. LCD display for easy operation; simply coat the probe with coupling agent, press it firmly directly below the container, and wait until the echo is appropriate. Main applications: 1. Level measurement for household gas cylinders, carbon dioxide fire extinguisher cylinders, refrigerant cylinders, oxygen cylinders, and syrup cylinders. 2. Real-time and accurate monitoring of the fuel level in the fuel tanks of vehicles, ships, aircraft, generator sets, and internal combustion engine equipment. 3. The probe is installed inside the tank wall to measure water depth on the ship. 4. Precise measurement of the liquid level in tank trucks, railway tank cars, and tank ships (all liquids with known sound speeds such as milk, syrup, liquid carbon dioxide, liquid nitrogen, etc.) or oils (gasoline, kerosene, diesel, engine oil, crude oil, vegetable oils). 5. Precision measurement of oil levels in various oil tanks and drums used for oil refining and storage. 6. Real-time and accurate monitoring of the liquid level in storage tanks, containers, and vessels used in chemical plants – including liquids such as brine, phenol solution, nail polish remover, liquefied gas, liquid carbon dioxide, liquid nitrogen, liquid chlorine, hydrochloric acid, sulfuric acid, *ao acid, chloroform, propylene, methyl tert-butyl ether, unsymmetrical dimethylhydrazine, **ammonia, butadiene, vinyl chloride, light hydrocarbons, bromine, anhydrous hydrogen fluoride, toluene, hydrogen sulfide, xylene, tetrachloroethylene, ethylene oxide, propane, ethanol, Freon, diethyl ether, ethylene, ammonia water, methanol, and all other liquids for which the sound speed is known). 7. Level monitoring of liquids (vegetable juice, fruit juice, grape juice, vinegar, soy sauce, alcohol, syrup, cola, sugar water, tea) in storage tanks, storage barrels, and storage containers in food factories, sugar mills, yogurt factories, soy sauce factories, wineries, vinegar factories, beverage factories, tea beverage production lines, carbonated beverage production lines, and cola factories. 8. Level detection of liquids (traditional Chinese herbal medicine solutions) in storage tanks, storage barrels, and other storage containers in pharmaceutical factories. 9. Liquid level detection for mineral water and purified water production lines, seawater desalination, as well as liquid storage tanks, barrels, and containers. 10. Fire water tanks, real-time monitoring of water levels in tap water systems, sewage treatment facilities, agricultural irrigation systems, canals, reservoirs, as well as rivers, lakes and seas. Technical specifications: Range: 3m (5–20m available); Display resolution: 1mm; Container wall thickness: 1–8mm (1–40mm available); Short-term repeatability: 1mm; Power supply: DC 9–36V; Measurement error: 1‰; Power supply: AC 220V (110V, 220V) ； 60-220V optional) Operating temperature of the unit: -20°C to +70°C. Display: LCD display. Operating temperature of the probe: -40°C to +100°C (250°C optional). Outputs: 485 interface with two sets of passive open and closed output contacts (defaultly closed). Working principle: As shown in the diagram on the left, when measuring liquid level, a modulated sound wave signal is sent out from the probe; after being reflected by the liquid surface, the echo signal is detected by the probe. The CPU calculates the liquid level height based on the relationships in the digital model.
