Accuracy: 2%, material: aluminum alloy, working pressure: 0.04Mpa, installation direction: vertical or horizontal, high precision, stable, widely used, easy to install. The all-aluminum steam turbine is compatible with mechanical oil gauges, oil guns, oil pumps, etc. It is generally used in gas stations, gas stations, and other oil loading and unloading industries. Mechanical gear 4-digit system, accurate measurement, 8-digit accumulation is easy to check. The oil gauge needs constant pressure from the oil pump to ensure accuracy, and the flow range is 20-1201/min. It cannot be used for natural stress. There should be a filter device to prevent the accuracy from being stuck by impurities. Features: Used for gasoline, diesel, kerosene and other fuels, the number of liters can be reset manually, and the total eight digits cannot be reset. Mechanical flow meter with handwheel for easy installation and calibration. It has the characteristics of large numbers, convenient reading, quick return to zero rotation, flexible horizontal or vertical installation, etc. Suitable for non-commercial use.
