Etrans-FTT FIXED TYPE THERMAL MASS FLOWMETER
Etrans -FTT Series Fixed Thermal Mass Flowmeter
Thermal mass flow meters are designed to measure the mass flow of gases. While standard flow meters require pressure and temperature compensation for accurate flow measurement, thermal mass flow meters can directly calculate the mass flow rate of the fluid without the need for such compensation. Mass flow meters are preferred due to their ease of application, lack of moving parts, very low pressure drop, wide measurement range, high accuracy, and high reliability. Thermal mass flow meters are predominantly used in sectors such as petroleum derivatives, the chemical industry, the medical industry, thermal power plants, and environmental protection.
