The FTB370 Series flow turbines are designed for flow rate measurement of water and many water based liquids. They are compact in design and have a wide measuring range. The liquid flowing into the FTB370 series is divided by guiding blades into four split streams. The uniform loading of the bearings from four sides causes the forces to cancel themselves out and wear gets reduced to a minimum. The extremely hard bearing materials also ensure an extraordinary life expectancy.
