Mass measurement: OG-VT0 pages

Oval Wheel Meter Innovations – from 1932 until today

Mass measurement: OG-VT
• Measurement of Mass
• Accuracy 0,3% of actual value
• Display of Mass, Flow and Temperature
• Current and Impulse output

Description
Mass meters of Bopp & Reuther are based on the decades proven oval
wheel meters with intelligent signal processing. The electronics converts
the measured volume under consideration of the current fluid
temperature and the associated actual density into a mass signal. For
further signal processing a scalable pulse output and a 4-20mA current
output are available for the actual value.
The OG-VT Series is used for precise measurement of liquified gases,
deionized water, acids, alkalis, fats, alcohols, fuels, oils, solvents,
paints, coatings, dispersions, condensation polymers, adhesives, etc.
Electronics:
-MFE-3:
Pulse output, current output 4-20mA,

current loop powered
-UR06:

universal computer with optional Ethernet interface
Input for two transducers, OIML approval
Temperature input, 10-point linearization,
2x current inputs for additional sensors
(density, temperature)
