Promass 83 Coriolis Mass Flowmeter
Promass measuring instruments make it possible to simultaneously record several
process variables (mass/density/temperature) for various process conditions
during measuring operation. Promass sensors, tried and tested in over 100,000
applications, offer the following:
• Multivariable flow measurement in compact design
• Insensitivity to vibrations thanks to balanced two-tube measuring system
• Immunity from external piping forces due to robust design
• Easy installation without taking inlet and outlet runs into consideration
The measuring principle is based on the controlled generation of Coriolis forces.
In the sensor, two parallel measuring tubes containing flowing fluid oscillate in
antiphase, acting like a tuning fork. The Coriolis forces produced at the
measuring tubes cause a phase shift in the tube oscillations. At zero flow, in other
words when the fluid is at a standstill, the two tubes oscillate in phase (1). Mass
flow causes deceleration of the oscillation at the inlet of the tubes (2) and
acceleration at the outlet (3).
