Product information "Flow Meter HDO 500 Niro/Niro"

Design: without explosion protectionViscosity
: up to 1,000 mPasHint
: The nominal diameter of the flow meter is DN 50



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

* Die max. Fördermenge ist ein ermittelter Wert mittels Prüfstand und gemessen mit Wasser bei einer Mediumstemperatur von ca. 20° C. Die Messung erfolgt am Druckstutzen der Pumpe, ohne Schlauch, Zapfpistole oder Durchflussmesser. Die im Einsatz erzielbare Fördermenge ist niedriger und hängt von der individuellen Anwendung, den Medieneigenschaften sowie der Konfiguration der Pumpe ab. Die max. Förderhöhe ist ebenso abhängig von Pumpenausführung, Motor und Medium. Die Viskositätswerte werden mit Öl ermittelt.

** Prüfaufbau: Medium Wasser / Diesel, Durchfluss in Vorzugsrichtung, Beruhigungsstrecke 0,2 m vor und nach dem Durchflusszähler
