Hydraulic Flow Meter Frequently Asked Questions

A hydraulic flow meter measures the flow rate of hydraulic fluid in a system, typically using mechanical, turbine, or differential pressure technologies. It helps monitor system performance and detect inefficiencies or leaks.

Turbine flow meters and gear flow meters are commonly used for hydraulic systems due to their high accuracy, pressure tolerance, and compatibility with viscous fluids.

Most high-quality hydraulic flow meters offer accuracy within ±1% of reading, with some precision models achieving ±0.5% or better depending on calibration and application.

Yes, many hydraulic flow meters are designed to withstand pressures up to 20,000 PSI or more, making them suitable for demanding industrial and mobile equipment applications.

Hydraulic flow meters typically measure flow from as low as 0.1 GPM up to several hundred GPM, depending on the size and type of the meter.

Most mechanical flow meters require occasional cleaning or calibration checks, especially in systems with particulate contamination. Maintenance frequency depends on fluid cleanliness and operating conditions.

Consider fluid type, operating pressure, temperature, flow range, required accuracy, and port connections. Consulting the manufacturer’s specifications or an applications engineer can help ensure proper sizing.
