Micro Oval Gear Flow Meter – High Precision for Small Flow Measurement
What is a Micro Oval Gear Flow Meter?
A micro oval gear flow meter is a positive displacement (PD) flow meter that uses two interlocking oval-shaped gears to measure liquid flow. As fluid passes through the meter, it causes the gears to rotate, and the rotation speed is directly proportional to the flow rate.
Key characteristics include:
✔ High precision (typically ±0.5% to ±1% of reading)
✔ Compact and lightweight design
✔ Low maintenance requirements
✔ Suitable for viscous and clean liquids
