Laser Level Measurement (Part 1 of 2)

Laser level measurement sensors emit a laser beam towards the material and measure the remnants of the beam that are reflected from the material. These systems determine the location of the material using the time-of-flight that the laser beam takes to travel to and return from the material. click for more...

Stating the Facts:
Considering Flow Turndown in Terms of Flow Accuracy

We found that most applications do not require a flowmeter with a high turndown, and that increasing turndown beyond, say 10-to-1, produces only marginal improvement in the range of flows (velocities) that can be measured. click for more...
