Coal Gas Flow Meter



Our company’s name figures in the list of renowned Manufacturers, Suppliers and Exporters of Coal Gas Flow Meter from Maharashtra. The Coal Gas Flowmeter we make available is microprocessor controlled and provides reliable and accurate gas mass flow measurement. Owing to our brilliant logistics network, we are capable of delivering bulk orders of the Coal Gas Flowmeter within the promised time frame.

Details
  • The model MFML-1000 series Thermal Mass Flow Meter is the instrument of choice for reliable and accurate gas mass flow measurement Specially For Coal gas Applications where Tar and Moisture is Present and The Temperature May be Higher Than Normal Applications Than 60 Degree Celsius, which is based on constant temperature differential technology for air and other process gases in range from 0 – 30 NMPS.
  • Because neither temperature nor pressure measurement are required. MFML-1000 series reduces installation cost and vastly improves system accuracy.
  • The meter is easily installed or retrofitted with minimum down time and provides superior long term process reproducibility and easy serviceability.
  • MFML-1000 Insertion type flow meters are available in probe sizes from 4” to 50 ” with either compression fitting or flange connection.
  • The transmitter provides a 4-20 mA linear output signal and optionally an RS485 serialized digital output signal. Other analog outputs are also available.
  • Programmable Logic Controller Is Used which Shows Flow rate, Total Flow, Velocity, MMBTU and Voltage Signal Received From The Transmitter/Thermal Flowmeter.
  • There is a Provision Specially Offered to Display The MMBTU Values which are Usually Required .The Calorific Values Can be Programmed as Required and as Per Known MFML-1000 series flow meter utilizes a constant temperature differential (dT) technology.
  • The sensor has two elements. The reference RTD measures the gas temperature. The electronics heats the heated element above the gas temperature.
  • It is the job of the electronics to maintain a constant dT between the gas temperature and the heated element.
  • As the mass flow increases, the increased number of gas molecules removes more heat from the heated element. The electronics senses this temperature reduction and adds additional power in order to maintain a constant dT.
  • The amount of power delivered to the heated element, therefore, is just proportional to the mass flow rate.
