Why Choose Vortex Flow Meters For Compressed Air Measurement?

Plant managers often struggle with accurate compressed air flow measurement, leading to energy waste and inefficient system operation.

Vortex flow meters are ideal for compressed air measurement, offering accuracy up to ±1% in pipes from 15mm to 300mm, with stable performance across varying pressures and temperatures.

What Is A Vortex Flow Meter For Compressed Air?

Many industrial users find it challenging to understand how vortex meters work with compressed air systems.

A vortex flow meter for compressed air uses the principle of vortex shedding to measure flow rates, creating alternating low-pressure zones that generate measurable frequencies proportional to flow velocity.
