Turbine Meter RQ UST1
with Universal Smart Transmitter
and HART® Communication
Designed for the process:
• direct measurement of volume
and volumetric flow rate
• measurement of low viscosities
• high accuracy
• 2-wire technique
• status message for preventive
maintenance
Measuring principle
The turbine meter is an indirect volumetric meter. Its
main component is an axial turbine wheel turning freely
in the flowing liquid. The turbine wheel is set in rotation
by the fluid at a speed which is directly proportional to
the average velocity of the fluid in the free cross-section
of the turbine meter. The speed of the turbine wheel is
therefore directly proportional to the volumetric rate of
flow, with the number of revolutions proportional to the
volume that has passed through the meter.
The rotation will be transmitted through the housing wall
by means of a non-interacting magnetic-inductive
sensor to the electronic converter UST1. From there a
flow-proportional 4-20 mA signal, in addition to the
integral display (with e.g. actual flow rate, total volume
or resettable totalizer), is available .
Major applications are process control or flow control
loops in any branch of industry.
Technical data
Repeatability
 0,15 % of reading over a reduced flow range*
 0,25 – 0,3 % of reading for normal flow range*
The accuracy depends on the viscosity, flow
range and the requested nominal size.
Please contact our sales engineers for specific
information.
