When installing the sealant surface and condenser tank, should they be placed horizontally or vertically?

Vertical, I haven’t seen any horizontal ones.

I’m not quite sure what you mean; as long as it ensures entry from the side and exit from below, that should be fine, right?

Just make sure to identify the import and export positions. Low in, high out, or high in, low out – depending on needs and usage ； Whether that small container is horizontal or vertical depends entirely on the manufacturer’s preference; it has nothing to do with its functionality. Generally, the outlet pipe is placed horizontally if it is not inserted deep inside, whereas if it is inserted to a certain depth inside, it is usually placed vertically. 　

It is best to place it horizontally, and this is to take measurement errors into account. Explanation: 1. As the diaphragm box moves through its full range, there is a change in the \"volume of the sealing liquid\" inside the measurement chamber; volume displacement equals the change in the height of the sealing liquid column, and this constitutes an error. 2. Early double-diaphragm differential gauges had a considerable change in volume, which resulted in a significant change in the liquid level of the sealing fluid; therefore, it was necessary to install the condensate tank horizontally in order to minimize these level changes. 3. In modern transmitters, the measurement chamber features \"micro-displacement,\" resulting in very small changes in volume; the volume of the tee connection has also been practically optimized, so people no longer pay attention to the topic raised by the original poster. For standard condensate tanks, there are requirements regarding the length-to-diameter ratio (a larger ratio is better); the reason is explained in point 2. @jiaguoyun @WindHowling

The condensation tanks I have seen in person are placed vertically, while according to HG/T21581-2012 they are placed horizontally. General atlas for the installation of automation instruments and controls in the metallurgical industry, in vertical format. Horizontal or vertical, it depends on the installation requirements

It’s usually vertical; there must be horizontal cases as well in special situations!

According to the regulations, the volume of the condensation tank must be three times greater than the maximum operating volume of the differential pressure gauge, and the cross-sectional area of the tank must be at least equal to the operating area of the differential pressure gauge. It can be placed either horizontally or vertically as long as these requirements are met. However, when using a large-displacement differential pressure gauge to measure flow rate, the sensing element of such gauges moves significantly; when the differential pressure changes, more of the isolating fluid or condensate in the pressure guiding tubes is discharged. If the isolating or condensing tank is placed vertically, its small cross-sectional area results in unequal liquid columns in the tubes at both ends of the differential pressure gauge, causing static pressure errors. Therefore, it is better to place the isolating or condensing tank horizontally in such cases. However, with torque-balanced and capacitive diffusing silicon differential pressure transmitters, the displacement of the sensing element during operation is very small; in such cases, it is better to place them vertically, as a small amount of the measuring fluid and the sealing fluid must mix with each other. If the distance between the upper and lower layers of the isolating fluid is short, there is a greater risk of leakage or washout.
