Gear type flow meters VC I Construction 1 Housing 2 Cover 3 Gear 4 Plug 5 Sensor 6 Bearing I General product characteristics • High-precision measurements with excellent repeatability • Maximal measurement resolution if used with encoder • IO-Link technology available • Wide measurement ranges with appropriate design sizes Application-optimised specification Low pressure drop Any flow direction Wide temperature range High working pressure Low noise emission Consisting of two high-precision gears, the measuring unit is driven by the liquid flow based on the displacement principle. The gears...

Gear type flow meters VC Description I Standard version The standard versions come with an integrated pre-amplifier which converts the pulses from the magnetic sensors into square-wave signals which are then computed by an electronics into specific measurement values. The optionally available remote-electronics version is designed to handle extreme temperature ranges. I Encoder version with maximised measurement resolution Compared with standard sensors, encoders are capable of generating considerably more pulses, thus increasing measurement resolution by orders of magnitude....

Gear type flow meters VC Technical data I General characteristics Nominal sizes plate mounting (P) / pipe connection (R) Mounting position Flow direction Typical measurement accuracy Maximum pressure Maximum permissible pressure loss Ambient temperature Media temperature Sound pressure level The indicated measurement accuracy refers to the pulse volume, i.e. the percentage variance applies to the latest measurement value. The measurement accuracy tests performed can be traced to DAkkS (Deutsche Akkreditierungsstelle, German Accreditation Body). The measurement accuracy is up to +/- 0.3% of...
