Embedding Sensors and Actuators Corresponding Module: C1M3 : Flow Sensors
Document Content and Description Below
A. You want to measure the flow rate of air of density 1.225 kg/m3 in a differential pressure meter. The upstream pressure is 20 N / m2 and the downstream pressure is 15 N / m2. The meter has an are... a of 0.1 m2. What is the flow rate in m3 / sec? B. What advantage does a coriolis meter have over a thermal mass flow meter when measuring the mass flow rate of a gas? C. A You want to measure the flow rate of a gas at roughly 400°C, 15 Bar static pressure, and 150 m/s flow velocity. Which is the only type of flow meter, from the 7 types that we discussed in class, that you can use and why? D. What are three differences in the method and principal of operation between a variable area meter and a differential flow pressure meter? (note: this question is not asking about the specifications of the meters) E. The k-factor for a turbine meter for flow in a 1.5” (38.1 mm) diameter pipe is 110 pulses per liter. Your magnetic pickup assembly recorded a frequency of 150 Hz. What is the flow rate Q in liters per minute? [Show More]
