Features 1、Applicable Range: Multi functional liquid flow meter with a flow detection range of 5‑600L/H, suitable for detecting water, diesel, gasoline, and other liquids, supporting L, GAL, PTS, and m³ measurement units. 2、Reliable Material: The flowmeter is made of nylon material, pressure resistance and wear resistance. The sealing ring is subjected to force up and down to ensure no leakage. The imported Hall element prevents aging. 3、LCD Digital Display: This liquid flow meter adopts a high definition LCD display screen, providing clear and intuitive readings, and convenient adjustment, greatly improving detection efficiency. 4、G1/2in Flow Meter: This gear flowmeter has standard G1/2 inch interface, providing stable and reliable connection. The working temperature range is ≤ 80℃, and the allowable pressure resistance is ≤1.75mpa. 5、Application Fields: Including 2 liquid flow meters, widely applied in fuel dispensers, beer machines, water fertilizer integrated machines, household water purifiers, and other liquid flow control fields. Specification Item Type: Digital Flow Meter Material: Nylon Battery Type: 3 x AAA Battery (Not Included) Product Model: LCD-05OFZAT Interface Size: G1/2in Usage Temperature Range: ≤80℃ Load Capacity: ≤10mA (DC5V) Allowable Pressure Resistance: ≤1.75mpa Storage Temperature Humidity: -25-80℃, 25%-90%RH Flow Range: 5-600L/H (Over Water Detection) Pulse Characteristics: (Hz)=(2.5*Q)±5%, i.e. 150 Pulses Per Liter of Water Output Pulse Duty Cycle: 50±10% Digital Display Meter Parameter: Applicable Medium: Most Pure and Stable Liquids (No Impurities, No Erosion Liquids) Measuring Accuracy: ±5% Repeatability: ±0.5% Maximum Working Pressure: 20BAR Standby Time: 1 Year Single Count: 0.00-9999 Total Cumulative Count: 0-999999 Measurement Unit: L, GAL, PTS, m³ Single Metering Zero Clear: CAL 1. Clear Single Count Press CLEAR key when counting or in standby mode, LCD full screen display, release CLEAR key to return to standby interface, and single count is cleared 2. Clear Total Accumulation When counting or in standby mode, short press SETUP key to change to total accumulation display, short press CLEAR key to clear single count, then long press CLEAR key (more than 5s), after 5 seconds LCD screen will automatically return to standby interface, and total accumulation is cleared 3. Switch Display between Flow Rate and Total Accumulation When counting or in standby mode, short press SETUP key to switch between flow rate and total accumulation display 4. Pulse Setting When counting or in standby mode, long press SETUP key (more than 5s) to enter coefficient setting interface, digit flicker can be set, short press CLEAR key to modify the value of flicker digit, short press SETUP key to switch the flicker digit, after setting is complete long press SETUP key or wait for 30 seconds to exit coefficient setting and save the setting value; the current value is 1000, indicating 1000 pulses corresponds to 1L 5. Unit Setting During counting or standby state, long press SETUP + CLEAR key (more than 5s) to enter the unit setting screen, then press CLEAR key to switch units, after the setting is complete, long press SETUP key or wait 30 seconds to exit coefficient setting and save the setting 6. Quick Check Pulse Count and Total Accumulation Counting or standby state, long press the SETUP + CLEAR key (less than 5 seconds), then display the total count since the pulse and product power(non clear zero) Package List 2 x Digital Flow Meter
