QTY:1 XYW-80 100 125 127 150 liquid level gauge oil level gauge oil level gauge Working principle: it is installed outside the measured medium and connected to the liquid storage and solution tank through the perforated bolt. As the solution changes up and down, it drives the solution in the pipe column to move up and down, thus displaying the liquid flow in the container. Scope of application: It is widely used in liquid level measurement and control in the production process of machinery, electricity, petroleum, chemical, metallurgy, environmental protection, shipbuilding, construction, food, catering and other industries. characteristic: 1. It is made of PMMA material. It has been exposed to the sun for many years in tropical climate, and its transparency and color change is very small. 2. PMMA has excellent resistance to dilute inorganic acid, detergent, oil, grease and weak alkali, and medium resistance to inorganic acid. 3. It does not react with developer. 4. It is suitable for measuring the liquid level and interface of liquid medium in the container. 5. The indication is novel, the reading is intuitive, eye-catching, and the accuracy is high. 6. The measuring range is large and is not limited by the height of the storage tank. 7. The liquid level gauge is isolated from the measured medium, with good sealing, high reliability and safe use. 8. Simple structure, convenient installation, convenient maintenance, corrosion resistance, no power supply. matters needing attention: 1. Do not contact with organic solvents such as alcohol, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, and will be eroded by strong alkali and warm NaOH and KOH. 2. The screw torque shall not exceed 40N. m. Technical parameters: Material: Acrylic Measuring range: 50-1000MM (customized according to customer requirements) Hydrostatic test: 10MPa Tensile strength: 60-75Mpa Impact strength: 12-13KJ/m2 Temperature resistance: 100 ° C Corrosion resistance: high Shape: square Packing:1pc Warranty period: 120 days On Feb 21, 2023 at 00:40:11 PST, seller added the following information:
