Product information "Flow Meter HDO 250 Niro/Niro"

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 backlight impresses with its simple, on-demand display and operability, multilingual interface and compact design. Due to the rotating Oval gear meter and the magnets placed on the measuring wheels, it enables the precise measurement of the volume flow and measures non-flammable liquids such as lyes, mineral oils, hydrocarbons and solvents as well as highly flammable liquids precisely, quickly and, above all, efficiently. 

  • Optionally available 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 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 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
