The model MF100 series Thermal Mass Flow Meter is the instrument of choice for reliable and accurate gas mass flow measurement, which is based on constant temperature differential technology for air and other process gases in range from 0 – 250 NMPS. Because neither temperature nor pressure measurement are required. MF100 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. MF100 inline type flow meters are available in probe sizes from 1/4 to 6” with either NPT or flange connection, and insertion type flow meters are available in probe sizes from 4 to 36” 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.

MF100 series flow meter utilizes a constant temperature differential (dT) technology. The sensor has two elements. The reference RTD measures the gas temperatur

e. 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 remove 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
