Oval gear flow meters are the preferred choice for Fuel flow monitoring. This is because they offer stable performance, a wide measurement range, low pressure loss, strong viscosity adaptability, the ability to measure high-temperature, high-viscosity liquids, convenient calibration, and easy installation.
Furthermore, oval gear flow meters can be configured with a mechanical display, requiring no power supply, or with an intelligent configuration, powered by 24VDC, supporting various remote signal transmissions.
