Advantages of Digital Display

Clearer Readings

The Digital Diesel Flow Meter directly displays instantaneous and cumulative flow values with high accuracy, precise to three decimal places. Compared to mechanical pointer or counter wheel displays, which require manual reading and calculation, the digital display provides clearer and simpler readings.

Higher Accuracy

The digital flow meter only requires adjustment of the flow coefficient. The flow coefficient varies at different flow rates, especially at minimum flow rates, which affects its rangeability. The electronic display can effectively overcome this by using flow rate segmentation for comparison.

The Digital Diesel Flow Meter can improve flow accuracy to 0.25%.

Of course, digital displays have many more advantages.
