What are each of the different thermal mass flowmeters for?
ECO2 FMT200 - is the entry level device designed for air measurement only – Highly capable at measuring flow in compressed air systems and checking for leakage. Compressed air is an expensive commodity and accurate measurement of its use or of leakage in the system can pay for itself.
FMT230 /250 – these devices are ideally suited for OEM. Offering Modbus output, machine makers can write the code to ensure equipment component parts can talk to everything else.
FMT430 and 450 These two devices are for general use across the chemical, pharmaceutical and wastewater industries amongst others. The two variants can measure a multiple number of gases. The 430 measures mass flow for up to two gases, whereas the 450 is capable of measuring up to 8 gas applications. Four are onboard applications and as such the gas type, tube diameter and shape, line pressure and temperature are calibrated, and pre-programmed by the factory, but a further four applications are customisable by the end-user on site. Gas mixtures can be specified via the human machine interface (HMI) or via HART or a laptop using the Field Information Manager (FIM) software. It means one device can meet the needs of lots of different applications. Its flexibility extends to changing the pipe diameter or being able to program the device to specify if the gas flow is through a pipe or a duct. It is revolutionary in that this flexibility affords the requirement of only needing one spare instrument to fulfil multiple applications
Both the FMT400 series and 200 series offers the flexible components and installation has been simplified through clever design. A significant proportion of the cost of purchasing new instruments is in the installation and commissioning of them. Simple solutions such as offering weld on adaptors to reduce pipe alterations, offering pipe components with the correct measure of straight lengths. Thermal Mass Meters are commonly replacing aging orifice plates type meters. In order to reduce installation headaches, the wafer type process connection on ABB’s new thermal mass flowmeter models has been designed to be the same size as the orifice plate which means our wafer pipe component can replace the old orifice plate and be fitted very quickly and cost effectively.
FMT700 is used predominantly for automotive combustion efficiency testing. They are used prolifically in the automotive industry, however more broadly the combustion efficiency principle is as relevant to the combustion engine of a garden strimmer as to a high-end application on testing Formula one racing engines.
