Vortex Shedding Flow Meters

You are here: Home » Products » Flow Meters » Vortex Shedding Flow Meters

Racine Vortex Flow Meters utilise Ultrasonic technology to measure tiny vortices that form when media in the pipe move across a strut, these vortices are exactly proportional to flow rate. This innovative product results in a Flow Meter with very high turndown ratio of up to 70:1, very high accuracy reading of +/- 1% and a Flow Meter with an exceptionally low pressure drop.

With no moving parts and low maintenance requirements, the Racine Vortex Flow Meters are an excellent choice for OEM’s and End-Users working in the water and waste water industry and are most suited to measuring liquids, gases and steam.

MGA Controls are the UK distributor and are fully trained in Racine’s comprehensive range of Vortex Shedding Flow Meters. Below is an overview of Racine’s range of Flow Meters, however for specialist applications o for more information on any specific Flow Meter, please call our technical team on +44 (0) 870 803 2001 or send us an enquiry using the form below.
