In order to fulfill the changing demands of our clients, we are offering Thermal Dispersion Type Flow Metering System. These products are developed by the dedicated efforts of our R&D department for the better development of our products. Before the end dispatch, these products are stringently examined by the quality analyzers of our firm on varied parameters to ensure their flawlessness.

Principle of operation:

  • The thermal sensor uses the principle of heat dissipation
  • A heated sensor is inserted into the stream of gas flow
  • The cooling effect of the gas is measured, transducer and interpreted as flow
  • The cooling effect is a direct function of the heat transfer that takes place due to the flow of gas
  • The heat transfer in turn is a direct function of the velocity as well as density of the process gas
  • Hence variations in temperature and pressure in the process gas are automatically compensated
  • For all practical purposes the output signal obtained is pressure and temperature compensated “mass flow” signal
  • Thus the compensated flow independent of pressure and temperature variation is indicated without need for any separate transducers for the same

The user friendly features and main advantages of this flow meter are:

  • In areas of flow metering, where the process gas pressures are very low, conventional flow metering techniques present a no. of limitations. In case of Thermal Mass Flow meter, upstream pressure required is very low because pressure drop across the sensor is negligible. Hence it works in place where Orifice/Rotameter type flow meters have failed. For this reason it is ideally suitable for very low height gravity feeds, reflux lines, condensers/accumulator systems etc
  • There are no moving parts in the system. So choking, jamming effect are not observed even after very long run of the meter. There is no need to carry out periodic cleaning unless the fluid is very viscous or dirty
  • There is no need to measure variations in pressure and temp. because the basic principle allows us to get a compensated output for both the readings. This substantially reduces the total cost of the installed system as well as the maintenance, troubleshooting time, spares inventory and frequent calibrations
  • Flow ranges available are very large, typically 1:100 and more, as compared to 1:3 to 1:10 by orifice type flow meters and rotameters
  • As per recent requirements, hazardous service installations should have minimum possible threaded/flange joints. Unlike the Orifice type (6-8 joints) and rotameter type (2 joints), this requires only one joint, either threaded or flanged. This makes it a very safe and desirable choice
 
Sensor Operation:

The sensor has a reference element, measuring service temperature. The other element is heated electronically. The heat carried away by the fluid depends on the molecular flow across it. The electronic control circuit measures and controls so that there is a constant difference between the fluid temperature and the temperature of the heated element. The flow rate is displayed in unit of mass per time as per the calculations now. The totaled mass flow per desired elapsed time is also displayed hence.
 
Sensor Installation:

The sensor has a 1.5” flanged connection. It is to be fixed on the pipe line nozzle horizontally with heated element (indicated by a punched depression on the flange) on top and cold. The sensor has six terminals. They are to be connected to the flow indicator cum totalizer.

Being a customer-focused organization, we are engaged in offering Natural Gas Flow Meter. The offered range is designed to accept 3 inputs of flow, pressure and temperature at a time. As per these inputs and other fed in parameters, these products calculates the instantaneous natural gas flow rate to a resolution of 4.5 digits. Our range provides low drift operational amplifiers and industrial grade components for trouble free operation.

 

Applications:

 

  • Used for the natural gas flow metering based on Aga-3 Nx19 norms of orifice flow metering systems
  • The high accurate calculations and heavy algorithms fed in the instrument thus allows it to be used for custodial transfer of natural gas applications
  • Accepts three inputs – Flow (Ma), pressure (Ma), temp (Ma/ Rtd Pt.100)
  • The user is required to fed in – Dp transmitter range in mmwc, Pressure range in Kg/Cm2, Flow rate for retransmission output, orifice diameter in mm, pipe inside diameter in Mm, specific gravity, mole % Co2 gas, mole % N2 Gas, Dp threshold in %
  • Response time in microseconds
  • Automatic decimal selection in flow rate calculations
  • To give the highest possible Resolutions in the flow rate
  • Calculates flow rates in Nm3/Hr. or Sm3/Hr – as selected

 

Pre-requisite data from the client:

 

  • Max./ Min./ Operating flow rates of the system
  • Max./ Min./ operating pressure in line
  • Operating temperature
  • Line size
