Thermal flowmeter

Friday, 03 July, 2009 | Supplied by: Procon Instrument Technology

Sierra’s Steel-Trak model 640S immersible thermal mass flowmeter is now available in a special high-temperature option capable of operating in process temperatures up to 400 °C.

Constructed of heavy-duty 316 stainless steel wetted materials, the high-temperature version includes remote-mounted electronics and mineral-insulated cabling resistant to very high temperatures.

The meter is already in use in such critical applications as electrical power generation, stack gas measurement, petrochemical refining and steel-making.

One such application is in coal-fired power plants, where combustion air is pre-heated to temperatures approaching 260 °C prior to it being mixed with the pulverised coal and burned in the boiler to produce steam for electricity.

Featuring direct gas mass flow measurement, each model uses Dry-Sense technology for drift-free performance. The meter also features Smart Interface for field programming and meter validation and diagnostics.

All the company’s flowmeters are calibrated to exacting specifications.

The ¾" diameter sensor probe inserts easily into ducts and pipes and is offered with a wide range of process connections (including hot tap).

For very large ducts, multipoint flow averaging arrays are available, complete with a self-contained human-machine interface (HMI) panel that allows for touch-screen field programming and operation of the entire system.

Probes may easily be removed for cleaning or the optional built-in purge cleaning system (using external high-pressure air) may be used.
