Oval wheel meter for small flows

New at Schmidt Mess- und Regeltechnik: the small oval wheel meters of the OR Plus series, approved for the Ex area (Atex). These high-precision volume meters for liquids from 0.03 l / min are available with pulse output or multifunction electronics MFE.

They are often used to measure the flow of

  • industrial liquids,

  • chemical liquids,

  • mineral oils and fuels.

Examples of suitable material combinations:

Medium

Industrial liquids
up to 3000 mPa•s

Chemical liquids
up to 150 mPa•s
Mineral oils and fuels
up to 150 mPa•s
Housingstainless steelstainless steel (PVDF, PP)Aluminum
Oval wheelsstainless steelPEEKPEEK
SealsViton, EPDMViton, FEPViton, EPDF

The oval wheel meters are easy to install. They work very reliably and are insensitive to vibrations, pressure changes, pulsations, changes in viscosity. Their robust construction enables a long service life.
