How to change the range of explosion-proof electromagnetic flowmeter

1. Introduction to electromagnetic flow measurement process

Electromagnetic flowmeter is an instrument that calculates flow rate by sensing the speed of liquid or gas flowing through a pipe. The flow measurement range depends on the coil parameters and chip performance of the electromagnetic flowmeter. However, in practical applications, different occasions require different flow measurement ranges. Therefore, the range of the electromagnetic flowmeter needs to be modified.

2. Steps to modify the electromagnetic flow measurement range

1. Adjust the coil parameters

The coil parameters of the electromagnetic flowmeter affect the measurement range one of the important factors. If you need to increase the measuring range of the electromagnetic flowmeter, you can increase the measuring range of the electromagnetic flowmeter by adjusting the parameters of the coil.

The specific steps are as follows:

(1) Find the coil parameter adjustment device of the electromagnetic flowmeter, which is generally located on the casing of the electromagnetic flowmeter.

(2) Use the adjustment device to gradually adjust the coil parameters of the electromagnetic flowmeter until the required range is reached.

2. Replace the electromagnetic flowmeter chip

If the coil of the electromagnetic flowmeter has reached the upper performance limit, the electromagnetic flowmeter chip needs to be replaced. The performance of the electromagnetic flowmeter chip determines the measuring range of the electromagnetic flowmeter. Different electromagnetic flowmeter chips have different measuring ranges.

The steps to replace the electromagnetic flowmeter chip are as follows:

(1) Open the casing of the electromagnetic flowmeter and find the electromagnetic flowmeter chip.

(2) Remove the original electromagnetic flowmeter chip and clean it.

(3) Install the new electromagnetic flowmeter chip, paying attention to the direction and fixation.

(4) Recalibrate and debug the electromagnetic flowmeter to ensure the normal performance of the new chip.
