Massflow Measurement of Steam

Application

Saturated steam measurement for massflow rate

 

Requirements

Need to improve the current unstable measurement of steam flow rate.
Besides stable measurement, mass flow rate needs to be confirmed at this measuring point but minimize the number of additional measurement points.

Model : DY050/MV
Process Condition :
Size : 50 mm
Fluid : Saturated Steam ; 155 °C, 5.3 kg/cm2 abs
Flowrate : 0 - 1500 m3/h

Process Condition

 

Proposal

digitalYEWFLO Multi-Variable type can measure flow rate and flow temperature in real time. Temperature fluctuation is simultaneously followed for the output.
This enables high accuracy measurement with temperature offset calculation by steam table, and limits the effect of flow change and boiler oscillation.

Multi-Variable Type

Shedder bar with built-in temperature sensor:
  • The shedder bar, which is strong enough to be used as a thermo-well, incorporates a RTD sensor (Pt1000, Class A) for temperature measurement.
  • Mass flow rate is calculated based on measured temperature.
  • A high level of safety is assured without the expense or installation of a temperature sensor, and additional process connection is not required.

Multi-Variable Type

 

Comparison test DATA of saturated steam measurement

digitalYEWFLO vs YEWFLO (general type) + Temperature input + Pressure input

Beneath data shows the equality of output signal from “digitalYEWFLO Multi-Variable type” and “mass flow computer, receiving the data from digitalYEWFLO(General type), temperature sensor and pressure gauge”.

Test Data

digitalYEWFLO always output the optimal vortex signal with making full use of the latest Digital signal processing technology, and minimize the effect of fluctuation or vibration noise coming from boiler.

 

Advantage

digitalYEWFLO Multi-Variable type contributes to cost down, save-energy, and production efficiency of Saturated Steam measurement.

  • Chimie

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
