ABB Swirl Flow Meters

The ABB SwirlMaster is a unique flowmeter design, pioneered and patented by ABB – this design ensures uses a similar principle to Vortex, but due to its ability to measure from the ‘twist’ of the fluid, it does not require the straight installation pipework lengths demanded by Vortex flowmeters.

This means the flowmeter is ideal for applications where limited straight pipe is available – eliminating the need for costly installations or pipe modifications.

The ABB Swirl Flow Meters are Renewable Heat Incentive (RHI) compliant.

It uses a two-wire transmitter with leading edge DSP-Technology and advanced flow computer functionality. Signals from remote sensors – like pressure, temperature, density or gas content can be computed directly with the signals from internal flow and temperature – making the FSS450 ideal for direct mass flow or standard flow of gases and liquids or direct mass and energy flow on saturated and super-heated steam.

A guide on the flowmeter body inlet causes the fluid swirl creating a similar effect to a vortex flowmeter, the swirls are then counted by a piezo sensor, allowing the fluid velocity to be monitored.
