2. Qingtian Instrument teaches you how to solve the problem of measuring media that cannot reach the non full tube electromagnetic flowmeter?

Qingtian Instrument teaches you how to solve the problem of electromagnetic flowmeter when the medium cannot reach the non full pipe: When using an electromagnetic flowmeter for measurement, a full pipe of medium is a basic requirement to ensure measurement accuracy.. However, under certain special working conditions, there may be situations where the medium is not fully filled in the pipe, resulting in unstable or even impossible measurement results. To address this issue, electromagnetic flowmeter manufacturers provide the following solutions:

1. Understand the impact of non full pipe conditions. Non full pipe conditions can be understood as extreme situations where the measured liquid medium contains a large number of bubbles. There are two situations where the pipeline is not filled with liquid: when the liquid level is above the electrode level and when the liquid level is below the electrode level. Although the measurement data of the former may be relatively stable, there is a significant measurement error due to the inclusion of gas volume inside the pipeline; The latter will cause the electrodes to be exposed in the air, and the measurement circuit will be in a clear signal circuit state, making the electrodes unable to function properly.

2. Method for determining non full tube state Bubble discrimination method: Use a pointer multimeter to measure the electrode resistance. If the electrode circuit resistance significantly increases, it can be determined as an abnormality in the electrode c

ircuit, and then it can be judged that there may be an empty tube situation.

. The specific operation is to measure with a domestic multimeter multiplied by a range of 1k. If the measured resistance value is greater than 100 kiloohms, it can be determined that the electrode circuit is abnormal. Observe the discharge outlet: If conditions permit, observe the liquid discharge outlet at the back of the flowmeter. When the discharged liquid is clearly not filled, it can be determined that the installation position of the electromagnetic flowmeter is in a non full pipe state.

Thirdly, optimize the installation position and method to avoid non full pipe situations: When installing flow meters, it is advisable to avoid non full pipe situations as much as possible.

. The optimized installation position is to install the flowmeter at the low end of the pipeline or intentionally install it in the pipeline section where the liquid level rises in the U-shaped pipeline. Choose a suitable installation location: For working conditions such as direct discharge ports without any back pressure after gravity flow or flow meters that are prone to non full pipe conditions, special attention should be paid to selecting a suitable installation location to ensure that the medium can pass through the flow meter at full capacity.
