New from Omega the FTB700-S Series turbine meters that have a unique system of precisely-machined helical rotors and high-quality jewel bearings. The rotor is the only moving part. Small magnets on the rotor hub are electronically detected by a solid-state hall-effect sensor outside the wetted area. The turbine rotor uses journal-type sapphire and ruby bearings for minimum friction and maximum life. These bearings are ideal for long life in water and water based fluids and they have exceptional low-flow characteristics.

Nice to see my my views being backed up by no less a figure than Sabine Hossenfelder https://youtu.be/QoJzs4fA4fo
