The ten measuring ranges extend from 0.2–0.8 l/min to 2.5–50 l/min. Seven different material combinations for case, cover and seal also provide suitable solutions for problematic media. The brass and stainless steel models can operate at up to 100 bar service pressure and at a maximum temperature of 80°C. The rotating vane flow meter DRH is ideally suited for service in refrigeration technology, in mechanical engineering and in printed-circuit board manufacturing.
The flow meter may be connected to machine controllers and other control and supervisory systems through standard outputs from different electronics. A choice of models with three-digit LED indication, pointer indication and a practical plug-on display is available for local indication of the actual flow rate at the point of measurement.
The hermetically sealed rotating vane, the non-contacting sensing of the wheel speed with the help of a magnet and the extremely low wear PTFE bearing allow fault- and maintenance-free long-time operation. Protection type IP 65 means that the measuring instrument is also suitable for service under tough operating conditions.
