Thank your employer for the opportunity to work for the company in the conclusion of your letter. Show your employer the same gratitude you are hoping to get in return -- through a raise.
What is a thermal mass flow meter? As gas flows by the heated sensor (flow sensor), molecules of the flowing gas transport heat away from this sensor, the sensor cools and energy is lost. A thermal mass flow meter is a device which measures gas mass fl â¦.
Vortex flow meter is based on Carmen vortex principle, which adopts piezoelectric crystal as testing components. It is a new kind of stress detecting vortex flow meter. It has the advantages of wide range rate, high accuracy, low pressure loss, good medium generality, pulse signal output proportional to flow, convenient to connect with computer etc.
