Product information "Flow Meter HDO 250 Niro/PPS"

Design: without explosion protection
Viscosity: up to 1,000 mPas
: The nominal diameter of the flow meter is DN 25.


The first flowmeter with touchscreen display and backlighting convinces with its simple, demand-oriented display and operability, the multilingual interface and the compact design. Thanks to the rotating Oval gear meter and the magnets placed on the measuring wheels, it enables accurate measurement of the volume flow and at the same time 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 in explosion-proof design
  • Media examples: Paints, lacquers, mineral oils, acids, alkalis, mineral oils,  solvents

Features & Advantages

  • Measurement according to the oval wheel principle
  • High measuring accuracy due to overtravel correction
  • Low pressure losses in the system
  • Touch screen display with self-explanatory, multilingual user interface
  • Relay module for quantity preselection can be retrofitted at any time
  • Approved according to ATEX Directive 2014/34/EU, category 2

* The maximum flow rate is a value determined by means of a test bench and measured with water at a medium temperature of approx. 20 °C. The measurement is carried out 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
