Questions about KROHNE flowmeters

1. First, it is necessary to determine what type of flow meter it is. Generally, when placing an order for such a meter, the manufacturer will already have the relevant settings configured; the meter is also calibrated before leaving the factory. Additionally, we carry out further calibration of the meter before installation. If the zero point is not accurate, it is of course necessary to perform zero-point calibration. 2. There are many types of flow meters available in Cologne, including common ones such as electromagnetic, float-type, mass-type, and vortex-type flow meters. Generally, there is no need for us to set any parameters ourselves, as the manufacturer has already done that; all we need to do is check things like the diameter and range, etc. Appropriate modifications will be made once it is put into use, such as small-flow cutoff, and so on. 3. As for instruments,... it’s better not to try to learn about them in this way for now. Focus on the principles, calibration, installation, debugging, commissioning, and maintenance – go through each step one by one! No matter how detailed the parameter settings are, they aren’t of much use when you’re not familiar with this instrument. Do it step by step!

For a new electromagnetic flowmeter, you simply need to adjust the measurement range to the desired value. If the converter is replaced, then some parameters need to be set again. There are various series of Coriolis flowmeters; taking the IFC300 as an example, the parameters that need to be adjusted include: SIZE (diameter), selection and setting of the GK, GKL, and GKH constants (the values must match those on the flowmeter’s sensor), as well as the excitation frequency and range. The other parameters can be left at their default values. The parameter settings for electromagnetic flowmeters are more or less the same; since I don’t have the user manual, the specific procedures require you to follow the steps outlined in the manual, navigating through the menu to make the necessary adjustments one by one

What type of flow meter? There may be more KROHNE electromagnets; for these, it’s only necessary to set the output.

In this way, no one can answer; at least tell us what kind of flow meter it is. If you go to the hospital, just say I’m sick; then the doctor won’t know what to do either.

I agree. Even if you’re a beginner, you still need to specify what type of flow meter it is; otherwise, how can we discuss it?

Just match the main range coefficient with the central control!

Generally, you provide the parameters to the manufacturer, who will produce the product according to your requirements. The parameters at the time of manufacturing are already set and calibrated; usually no further adjustments are needed on-site, unless there is a drift in the zero point, in which case a zero-point calibration can be performed. Another situation where adjustments may be necessary is when there is signal interference, in which case low-level signals can be filtered out

You need to first determine which type of flow meter to use. If it’s an electromagnetic flow meter, generally only the pipe size and range are required; in addition, there are things like a 4–20mA output as well
