["Feature:\n*When it appears - normal flow rate but the meter does not count, when the DISPLAY button is pressed, the meter is turned on. In this for case, the possible cause is: 1. the impeller is stuck or damaged; 2. the sealant material is wrapped around the impeller; Solution: Remove the meter and ensure that the impeller rotates freely.\n\n*When it occurs - the flow rate is reduced and the meter does not count when the DISPLAY button is pressed, the meter is turned on. In this for case, the reasons may be caused by: 1. The meter is partially blocked by the dried liquid; 2. Below the minimum flow rate; Corresponding solution: remove the instrument to ensure that the impeller rotates freely; 2. Increase the flow rate\n\n* When the meter is not working properly, it may be due to a board failure or a button failure. The corresponding solution: replace the circuit board\n\nSpecification:\n\nOperating voltage: 2.3-3.3V\n\nBattery type: 2 x AAA LRO3 batteries\n\nThread size: 1inch NPT\n\nMeasure accuracy: ±1%\n\nMaximum working pressure: 20BAR\n\nFlow range: 15-120L / Min\n\nSingle count: 0.00-9999.9\n\nTotal cumulative count: 0-99999\n\nWorking temperature: -10°C ~ +60°C(14°F~140°F)\n\nStandby time: 1 year\n\n Note:\nAnd due to the difference between different monitors, the picture may not reflect the actual color of the item.
