Fluid Components International MT100 Series multipoint thermal mass flow meters

Click2Contact

The MT100 Series multipoint thermal mass flow meters from Fluid Components International are designed to assist with the optimisation of combustion or preheated air to large boilers, stack emission monitoring and reporting, and flue gas/scrubber balancing. They provide temperature-compensated direct mass flow measurement of air and gases for precise, repeatable measurement in large diameter pipes, stacks and rectangular duct installations.

The flow meters are available with 2–8 flow rate sensing points to overcome common issues such as distorted flow profiles. Multiple sensors are inserted at various depths within a pipe or duct and their outputs are multiplexed and averaged to produce the flow rate within the process line.

The series can measure flow rates over a wide range, from 0.25–1000 SFPS (0.07–305 NMPS), with 100:1 turndown and with an accuracy of ±0.75% of reading, ±0.5% of full scale. They can also provide temperature measurement from -45 to 454°C with an accuracy of ±1.1°C.

Dual, isolated, high-resolution 4–20 mA outputs compliant with Namur NE43, HART, Modbus, 0–1 kHz frequency/pulse and a USB port are included. Foundation Fieldbus and Profibus-PA are also available.

The large, colour, touch-screen LCD readout provides comprehensive process information with both analog and digital displays of flow rate, temperature and totalised flow and sensor status diagnostics. The electronics also includes a data logger feature with which flow rate, temperature and totalised flow, as well as fault codes, can be recorded on a removable 8 GB microSD card.
