As shown in the figure, what is the installation height of the condensation tank?

As shown in the figure, what impact will it have on the results if the installation heights of the condensation tanks are not on the same horizontal level? What are some concise solutions? Thank you for the reply.
If it is an isolation fluid, its loss has little impact; however, the heat transfer due to steam condensation differs, which can cause deviations. In cases where the scale is large, the impact is minimal – the issue can be resolved by shifting the position or by fine-tuning it by adjusting the opening degree of the root valve
An installation height that is not at the same horizontal level can cause additional measurement errors
If the positive pressure side is high, the measured value will be higher than the actual value; if the negative pressure side is high, the measured value will be lower than the actual value. It’s actually a matter of zero-point offset. When the system is functioning properly, that is, when the condensate has been collected and the pressure on the positive side is high, there should be no pressure difference in the pipes, so it should be zero. However, the pressure on the positive side of the transmitter is equal to the static pressure of the condensate plus the pipe pressure, and the pressure on the negative side of the transmitter is also equal to the static pressure of the condensate plus the pipe pressure; these two pressures should be identical. But since the two condensation pipes are not at the same height, the static pressure of the condensate differs, resulting in a small deviation from zero in the zero-point differential pressure. When the pressure on the positive side is high, the zero-point differential pressure is positive; otherwise, it is negative.
It doesn’t matter; just install it however works, as long as it looks good. You can adjust the transmitter gauge later to get it right.
The absolute level is very difficult to achieve; just zero it out after filling it.
