What is the accuracy of the SICK ultrasonic flow meter 600 in Germany?
Thread Content
Is there a difference in the accuracy of flow meters depending on the operating conditions? It says Qb, 1. in the manual. . . What does 5% mean?
My understanding is that the precision is at the 1.5 level, with no difference between operating conditions and standard conditions.
Operating conditions and standard conditions require compensation calculations for temperature and pressure, right?
There are some other parameters: I don’t understand them. Measurement accuracy: Repeatability < 0.2 of the measured value ； Uncertainty: ±0.2 measurement value. Are these related to the instrument’s range? The maximum air volume is 400–1,000,000 cubic meters per hour.

Ultrasonic level gauges are of poor quality, but multi-channel ultrasonic flow meters are commonly used instruments for trade measurement.

Different types of flowmeters have different usage methods, so it’s not right to dismiss them all just because they don’t work well in one particular area or with one particular brand. If they weren’t effective, so many customers wouldn’t purchase them.
Oh no! After talking for so long, I’m still confused. This ultrasonic flowmeter doesn’t measure accurately either.
Qb is the cumulative amount, right? Is it measured based on a 1% error margin?
