Item Type: Flow MeterMaterial: ABSStandard: VerticalMedia: Methanol, diesel fuel, kerosene, chemical liquid, urea waterImporters: 1in internal threadMeasurement Accuracy: 1%Repeatability: 0.5%Maximum Working Pressure: 20BAROperating Voltage: 2.3 - 3.3VStandby Time: 2 YearsFlow Range: 10 - 120L / MINSingle Count: 0.00 - 999.9Total Cumulative Number: 0.00 - 999999.9Unit: L / L, gal / GAL, pint / PTS, quart / QTSSingle Measurement Cleared: RESETBattery: Built-in battery, 2 x AAA batteries, 500mAh(include batteries)Setting Units of Measurement:1. In the standby mode, or raise the amount of current display state2. Press CAL + RESET button for 5 seconds3. Enter unit conversion settings, press the RESET button4. Followed by LTR - GAL - PT -QT - LTR choose the unit of measurement5 .While the cumulative filling volume displayed in the current unit of measure conversion after6. Press the MENU key for 3 seconds to exit the unit conversion settings.Operating Instructions1. Measuring Unit SettingUnder standby state or current amount display state, press and hold MENU+RESET buttons for 5 seconds to enter unit conversion setting, then press RESET button to select unit in turn of LTR - GAL - PT - QT - LTR. Press and hold MENU button for 3 seconds to exit unit conversion setting.2. Accumulative and Current Amount ResetPress and hold RESET button and LCD screen displays on full screen, wait till the full screen display end then loose the RESET button. At this time the accumulative amount and current amount is reset.3. Error Coefficient and Accumulative Amount InquireUnder standby state, press MENU + RESET button together, then LCD display shows the error coefficient on the upper row, and accumulative amount on the lower row.4. Error Coefficient CalibrationUnder standby state or current amount display state, press and hold MENU button for 3 seconds to enter error coefficient calibration mode. The first digit flashes, press MENU button to change position of the digit, and press RESET button to change digit. As this coefficient increases, output oil quantity reduces. Then press and hold MENU button for 3 seconds to end error coefficient calibration and return to current amount display state, and the current amount is reset as zero. The calibration error coefficient range is 0.1000 to 9.9999. For example, original coefficient is 1.000, when it displays 100 liters output of oil, the actual oil output is 100L. If you need 2 liter reduced, set the coefficient as 1.020, then the output would be 98L.5. MaintenanceWhen battery voltage is too low, a battery symbol appears on the LCD display, which reminds user to replace battery. Too short battery life can cause damage to the meter because of battery leakage. This meter has designed standby life of about two years, but we suggest customer to replace a battery each year, and check battery electrodes if there is any rust. Battery should be removed if not usi1The flowmeter control panel adopts modular design, multiple measurement units conversion, complete functions, convenient operation and simple structure.2It can be used to measure methanol, kerosene, diesel, fuel, urea water. It is widely used in petroleum, chemical, pharmaceutical, transportation, food and other industries and commercial fields.3Digital LCD display, high?definition display shows instantaneous and cumulative flow and NPT counter.4Clear and accurate measurement, intuitive and clear reading, high reliability, measurement accuracy 1%.54 unit options, liter (L) / gallon (GAL) / pint (PTS) / quart (QTS), used in different countries. Easy to clean, install and maintain.1. This product requires 2 x AAA batteries, more convenient for you to use, and comes with 2 x AAA batteries replaceable batteries2. Hint of insufficient battery power: LBAT is displayed when the battery voltage is 2.2V ? 2.4V to remind the user to replace the battery.3. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.1 xFlowMeter1 x Adapter2 x Rubber Seal Ring
