II. Product Details (PRODUCT DETAILS)

1. Precision Metering: Accuracy for Cost Control

• ±0.5% Industrial-Grade Accuracy: Eliminates guesswork in fluid dispensing, critical for businesses that bill by volume (e.g., auto repair shops) or track inventory (e.g., industrial facilities). Unlike mechanical gauges with ±2% error, this digital meter ensures no over-dispensing or revenue loss.
• Multi-Function Display: The backlit LCD screen shows instant flow rates (e.g., 15 L/min) to adjust dispensing speed, cumulative total to track monthly usage, and resettable total for single-job measurement. Unit switching (L/gal) caters to global user needs.

2. Broad Compatibility & Durability

• Medium-to-High Viscosity Support: Works seamlessly with lubricants (up to SAE240), diesel, antifreeze, and window wash liquid—no need for separate tools for different fluids. The meter’s material resists corrosion from harsh fluids like antifreeze.
• Robust Build: The gun body combines high-impact plastic (for light weight) and corrosion-resistant metal (for pressure resistance), withstanding daily drops and impacts in busy workshops. The 100 BAR max pressure rating suits high-pressure fluid systems.

3. Ergonomic Design: User-Friendly Operation

• Non-Slip Ergonomic Grip: Reduces hand fatigue during long sessions (e.g., refueling 20 fleet vehicles). The lightweight design (inferred <1kg) allows one-hand operation.
• Smooth Trigger & Visible Display: The trigger offers precise flow control (from 1-25 L/min), while the backlit screen ensures visibility in dimly lit areas—no need for extra lighting.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Automotive Workshop Oil Change Services

1. Setup: Connect YD51-015 to the shop’s oil pump via 1/2 BSP/NPSM thread; reset the meter to zero;
   
   
   2. Dispensing: Use the ergonomic grip to hold the gun; trigger to dispense 4L oil per sedan (≈16 seconds at 15 L/min); the screen shows instant flow and total;
   
   
   3. Billing: Share the meter’s total (e.g., 4L) with customers for transparent billing;
   
   
   4. Efficiency: 30 cars serviced in ~8 minutes; backlit screen works in the shop’s dim corners.
   
   
   Effect: ±0.5% accuracy ensures fair billing; ergonomic design reduces technician fatigue.

2. Fleet Maintenance Center Diesel Refueling

1. Setup: Attach YD51-015 to the diesel storage tank’s pump; switch the meter to "L" unit;
   
   
   2. Refueling: Dispense 60L diesel per truck (≈4 minutes at 15 L/min); record the cumulative total for each vehicle;
   
   
   3. Tracking: At week’s end, use the meter’s cumulative total to analyze usage and identify inefficient trucks;
   
   
   4. Durability: The gun withstands outdoor use (temperature: 5-35℃) and diesel exposure.
   
   
   Effect: Precise tracking cuts fuel costs; broad compatibility fits diesel needs.

3. Industrial Machinery Coolant Topping-Up

1. Setup: Connect the gun to the antifreeze pump; ensure the meter’s working pressure (5 BAR) is met;
   
   
   2. Topping-Up: Dispense 8L antifreeze per machine (≈32 seconds at 15 L/min); the screen’s backlight works in the plant’s low-light corners;
   
   
   3. Temperature Adaptability: The gun functions normally at -10℃ (within -20℃ ~ +60℃ range);
   
   
   4. Compatibility: Antifreeze does not corrode the meter’s material.
   
   
   Effect: Cold-resistant design suits plant conditions; accurate metering avoids coolant waste.
