Frequently Asked Questions (FAQs)
1. What is flow sensor and its types?
The different types of flow sensors generally fall into one of three categories: Positive displacement flow sensors. Mass flow sensors. Velocity flow sensors.
2. What are flow rate sensors?
The Flow Rate Sensor measures the velocity of water in studying the discharge, flow patterns, and sediment transport of a stream or river. ... Flow rate data can be used to calculate the discharge value for a stream or determine the sediment transport of a stream.
3. How does a flow detector work?
These mechanical water flow meters work by measuring the speed of flowing water running through the pipe that causes a turbine or piston to rotate. The volumetric flow rate of the water is proportional to the rotational speed of the blades.
