Sample interview questions: Can you explain your knowledge of different types of flow meters used in hydronic systems and their accuracy ratings?
Sample answer:
Flow rates are a fundamental aspect of Hydronic systems and the accuracy of flow rates is of critical importance for the efficient operation of these systems.
There are different types of flow rates used in Hydronic systems and each type has its own accuracy. The most common types of flow rates are:
- Ultrasonic flow rates are the most accurate type of flow rates and can measure flow rates from 0.01 to 15 m/s. They are used to measure the flow rate of water, oil, and gas.
- Differential pressure flow rates are less accurate than ultrasonic flow rates but can be used to measure flow rates from 0.2 to 10 m/s. They are used to measure the flow rate of water and oil.
- Magnetic flow rates are accurate and can measure flow rates from 0.1 to 10 m/s. They are used to measure the flow rate of water, oil, and gas.
When selecting a flow rate for a Hydronic system, it is important to consider the following factors:
- The size of the pipe will … Read full answer
