The differential-pressure cone flowmeter is an innovative high-precision flow-measurement flowmeter specially designed for high-accuracy fluid-measurement under various difficult conditions. It realises throttling by suspending a V-shaped cone at pipeline centre, forcing fluid to flow around the cone centred on pipeline centreline. This geometry brings multiple advantages compared with traditional throttling elements. Due to its unique design, fluid flow status exerts no obvious influence on its measurement accuracy, so it is suitable for difficult-measurement scenarios such as insufficient straight-pipe sections, turbulent-flow conditions and two-phase mixtures.

It features low pressure loss, favourable signal-to-noise ratio (SNR) and wide turn-down ratio. Meanwhile the equipment has self-cleaning and flow-profile-reshaping functions.
