Description

1.Introduction


The meter is designed and produced according to worlds latest Coriolis technology, with better appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, metals and mining, power, pulp & paper, water & wastewater industries, etc.
  2. Operating principle
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift, and amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
  3. Features
● Measurement is not influenced by flow density, viscosity, temperature & pressure;

● Low requirement of straight pipe, because nothing inside holds back the flow;

● Internal nominal diameter varies from DN*6 to DN**0;

● Low power dissipation; stable zero point; better accuracy;

● Meter is ARM system, with 3 calculators to count density, temperature & mass flow rate;

● Transmitter is assembled by surface mounting technology, with self-inspection function;

● Ex-mark is Ex ib II B/II CT1~T6 Gb.
