About This 2-Inch FLOW METER: Before use, please calibrate the flow meter with the liquid to be tested. And the flow rate of the liquid should exceed 15 gallons per minute, if the flow rate is too slow, the measured result of this flow meter may be incorrect. The Battery inside has been removed before shipment. MULTI-FUNCTION DISPLAY: High-definition LCD display, can read single cumulative flow, instantaneous flow and total cumulative flow. The clear function can clear the value of cumulative flow, to make sure it is always within the measuring range. If your flow meter cannot work, please contact us in time. HIGH-QUALITY MATERIALS: The aluminum alloy housing is sturdy, durable and corrosion-resistant, which have a long service time. The PCB circuit board make the battery have a long service life, and safe in use. Please NOTE: the LCD display is not water proof INSTALLATION: The flowmeter can be installed in horizontal and vertical directions, but the flow direction of the liquid needs to be consistent with the direction of the arrow on the flowmeter. There is no direction requirements for the installation of the display screen. MEASURABLE LIQUIDS: The turbine flow meter can used for measuring the water, water, gasoline, diesel, kerosene, methanol and other low-corrosive, non-viscosity liquids. THE LED DISPLAY IS REPLACEMENT: if the flow meter stops metering as it should, please contact us in time, it usually can be solved by replacing a new LED display.
