Gas /Steam Flow Meter is most suitable for measuring compressed air consumption, Biogas & LPG consumption in various industries.

Application Sectors for Gas Flow Meter
  • Engineering & Automation
  • Textiles
  • Chemical/pharmaceutical
  • Food & Drugs
  • Petrochemicals
  • Fertilizers
  • Steel/ Aluminum
  • Sugar Factories/Distilleries


Introduction

  • The GFMc-150 flow meter is applicable for measuring flow rates of Bio-gas, LPG, Compressed air and other compressed gases in closed conduits.
  • It is best suited for applications where affordability, reliability and ruggedness are of prime concerns.
  • In conventional system of measurement, the differential pressure generated by orifice plate is measured by DP transmitter.
  • The output from DP transmitter after square rooting is accepted as proportional to flow rate.
  • This assumption is true only when the density is constant. Unfortunately density of compressible fluid is never constant.
  • The density of compressible fluid changes with line pressure and line temperature.
  • Thus, introducing errors in flow rate measurement.


Comparison with Vortex Flow Meter

ParameterOrificeVortex
Well established standardsAvailableNot Available
Suitability for high pressure & temperature application.Most suitableSeal fails in majority of cases after certain duration
InstallationEasy to installCritical & expensive because of Requirement of special machined pipe lengths.
Existing pipeline modifications for installationNo modifications required.Design is based on velocity & not on line size. As a result customer line size & selected flow meter size may differ.
Recalibration of transmitterEasy & can be done in houseHas to be done on a flow-rig and hence is expensive
Changes in Pressure, TemperatureTaken care during density compensationNeeds to be taken care of
Effects on resolution due to increase in line sizeNo effectResolution decreases with increase in line size
Suitability for low-velocity measurementSuitableStops the measurement
DurabilityNo moving parts and hence no wear and tear and virtually maintenance freeDiaphragm based sensor and hence is prone to wear and tear

Introduction

  • The SFMc-150 flow meter is applicable for measuring flow rates of saturated and superheated steam, mass flow rates of Boiler feed Water in closed conduits.
  • It is best suited for applications where affordability, reliability and ruggedness are of prime concerns.
  • It can be used as heat energy transfer meter to measure thermal energy using various fluids which are being used as the heat transfer medium.
  • In the conventional system of measurement, the differential pressure generated by orifice plate is measured by DP transmitter.
  • The output from DP transmitter after square rooting is accepted as proportional to flow rate.
  • This assumption is true only when the density is constant. Unfortunately, the density of the compressible fluid is never constant.
  • The density of compressible fluid changes with line pressure and line temperature.
  • Thus, introducing errors in flow rate measurement.


Features of Steam Flow Meter

  • Easy user-friendly programming
  • Password protected for all modes except display mode
  • Computer/Printer Interfacing with RS 232/RS 485 port with MODBUS RTU
  • Fault indication indicated by different error codes
  • Overflow indicated by blinking display up to 3000 readings (for more readings consult factory)
  • Data logging facility with 3450/ 6900 number of reading is available
  • Linear or square root operation
  • Universal power supply
  • Suitable for Saturated &/or Superheated Steam
  • Two-alarm setting configured on pressure input
  • Steam status indication (Saturated/ Superheated)
  • Pressure and temperature offsets generated by site condition can be compensated
  • Mass flow calculation as per ASME algorithm
