Flow meter HDO 250 aluminium/PPS
*Illustration may differ from the actual product
Description:
The first flowmeter with touchscreen display and backlighting impresses with its simple, needs-based display and operability, multilingual interface and compact design. Thanks to the rotating oval wheel meters and the magnets placed on the measuring wheels, it enables precise measurement of the volume flow and measures non-flammable liquids such as alkalis, mineral oils, hydrocarbons and solvents as well as highly flammable liquids precisely, quickly and, above all, efficiently.
- Optionally available in explosion-proof design
- Examples of media: paints, varnishes, mineral oils, acids, alkalis, mineral oils, solvents
Properties & advantages
- Measurement according to the oval gear principle
- High measuring accuracy due to overrun correction
- Low pressure losses in the system
- Touchscreen display with self-explanatory, multilingual user interface
- Relay module for volume preselection can be retrofitted at any time
- Approved in accordance with ATEX Directive 2014/34/EU, category z

* The maximum flow rate is a value determined by means of a test bench and measured with water at a liquid temperature of approx. 20 °C . The measurement is taken at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.
** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter
