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

Application Sectors for Gas & Steam Flow 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 standarsAvailableNot 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 pipe line 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

Compact Steam Flow Meter is based on the principle of differential pressure generated by Orifice element.

Features:
  • Designed as per ISO5167/BS1042.
  • On line density compensation delivers very accurate results.
  • Various Types of IBR/Non-IBR valves for isolation and drain.
  • Various Sizes of Orifice Assemblies with or without IBR Certificate.
  • Complete System is Engineered to suit your requirements.
  • Highly Reliable and Repeatable System; No Moving Parts.
  • Easy for Calibration.
  • GFM series flow meter are widely used for measuring flow rates of Steam ( Saturated & Superheated), Biogas, LPG, the air in closed pipes.

 

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 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.
