Product Overview

MEGA-TMF600 measures the gas mass flow based on Thermal Diffusion principle. One sensor measures the velocity of gas flow (Rh) and the other sensor detects the temperature shift of gas flow (Rmg). When there are two RTDs in the gas flow, Rh will be heated and Rmg will sense the temperature difference. As the velocity of gas flow increases, more heat will dissipate and so the temperature read by Rh will decline.

MEGA-TMF600 Thermal Mass Flowmeter design is based on a constant power measuring method, thus the RTD is heated on a consistent power and will be more durable and stable. Due to that, TMF-450 meter has less problem of zero-off which may cause a function failure of RTD due to overheating the term.

The dual line LCD display with 3 setting button
Wide Turndown ratio of 100:1, can also be expended to 200:1
No pressure loss and it can be used on pipes from DN25 to DN2000
It has a more compact design, which means smaller enclosure and thinner insertion tube probe
Measure mass flow and standard flow directly
It has a self-diagnostic function
It has high accuracy data acquisition circuit
High effective design of power supply
It can be installed/removed without stopping the process
Cost-effective model
Ex-proof version optional
Electrical structure of total isolation to ensure excellent EMC properties and avoid the interference from outside
