2 Application KOBOLD type DRS flow meters are used for measuring and monitoring liquids. Due to its compact construction the mini turbine is suitable for use with machines with minimum available space. Application Examples Beverage industry, devices for use in automatic beverage retail systems, washing machines, vehicles, farm equipment, developing machines in the photographic and printed-circuit board industries. Working priiple The flow meter operates on the turbine wheel priiple. The liquid first flows through a laminar flow element to eliminate turbulee and to route the flow stream to the turbine wheel. The turbine wheel then starts to rotate. This rotary motion is sensed non-contacting by magnets embedded in the turbine wheel and converted to a frequey signal. The frequey is proportional to the flow velocity. Frequey divider, analogue output or compact electronics with LED display and limit contacts are available as options. An integrated temperature sensor for simultaneous measuring of flow rate and temperature are available as an additional option. The vane is sapphire-supported: this ensures a high degree of linearity and long service life. 0
