Different types of level sensors and level sensing technology
The ultrasonic level sensor is probably the most widely used non-contact sensor since it is very versatile and can be used to calculate volume and flow rates in open channels. The …
Functionality and technology of level sensors - Process Industry …
The two main level sensor types are continuous level sensors that accurately measure levels to a specific limit and point level sensors that simply determine whether the liquid level is high or …
How do different types of level measurement devices work?
A sensor emits ultrasonic pulses which the surface of the medium reflects and the sensor detects again. The required time of flight is a measure for the distance travelled in the empty part of …
Tips common to all types of level measurement devices
Level echoes within the blocking distance cannot be evaluated due to the transient characteristics of the sensor and thus a reliable measurement is not possible. The blocking distance BD is …
