Temporary or permanent installation
The Vortex flow meter is perfectly suited for measuring flow and consumption of inert gases and steam in both clean or dirty gas environments. With no moving parts, these sensors are both durable and easy to maintain.
The design of this meter allows for precise measurements of most gases and steam no matter how heavily contaminated. With built-in pressure and temperature sensors, all parameters of your gas or steam system are monitored in one unit, saving you install and maintenance costs. The integrated display allows installers to set the flow meter without any additional equipment and for users to read the information in real time right at the meter.
Pipe sections are available from DN15 to DN300.
