Thermal dispersion mass flow meter is an ideal choice for a variety of gas flow measurement, such as combustion gas, flue gas, compressed air ,coal gas, liquefied gas .etc. Silver Automation Instruments provide robust thermal mass flow meter with cheap price and good delivery time. Below we list an application of cold blast air flow measurement by thermal mass flow meters, let's see the details:
Air Flow Meter Inquiry:
We need a flow meter for cold blast air. Cold blast air is delivered to blast furnace by turbo blower plant. We need a very reliable and accurate flow meter to cross check other two existing flow meters installed at same pipe line. These flow meters are old and orifice type flow meter, we don't want to replace them but we need to install a new flow meter for accurate flow measurements.
Kindly find below and quote most suitable flow meter. We need flow meter with pressure and temperature compensation

Reply to the Flow meter Enquiry:
Hi, thanks for your inquiry, after analyzing your Cold Blast Air flow meter technical specifications, we choose thermal dispersion mass flow meter; this flow meter can have 1.0% accuracy as you required, and the best part is that it can directly measure gas mass flow without external temperature and pressure compensation. We notice your pipe line is really large, thermal mass flow meter can have insertion type installation which will save you a lot installation work. Our technician calculates your parameters and thinks DN1000 insertion type mass flow meter is suitable pipe size for your application. Beside thermal dispersion mass flow meter has digital display for your observing the value in the field conveniently also easy for your future parameter configuration.
