What type are the sulfur pressure gauges used by marine friends? Is it useful?

As the title suggests, could there be a sulfur blockage?
Diaphragm pressure gauge, with jacket heating for the outlet pipeline.
Diaphragm gauges come in threaded and flanged versions; it is recommended to use flanged diaphragm gauges. Sulfur tends to crystallize, so such pressure gauges need to be cleaned and calibrated periodically to ensure accurate readings.
A flange diaphragm pressure gauge was used, but it has not been cleaned. Because it’s basically inaccurate; it won’t be usable for more than a month.
The flange diameter and the pipe diameter at the connection points should be as large as possible to ensure good ventilation and avoid dead zones; during the purging of the device, the crystalline impurities attached to the diaphragm should be removed, which should result in good performance.
Diaphragm pressure gauge, with heat tracing for the pipeline jacket; the flange diameter and the diameters of the connections should be as large as possible to ensure good ventilation and avoid dead zones. During the purging of the device, the crystalline impurities attached to the diaphragm should be removed, which should yield good results.
Flange diaphragm pressure gauge. We use this type as well, but the pipeline leading to it must have a jacket; if it doesn’t have a jacket, it gets clogged very easily. Every time we carry out maintenance here, we check the pressure gauge; after a month, we basically stop paying attention to the pressure parameters!
Pay attention to the angle of the pressure tapping tube, which should be vertical upward relative to the process gas pipeline.
Flange diaphragm pressure gauges, but over time, sulfur can solidify on the surface of the diaphragm, causing the gauge’s reading to drop; in such cases, it is necessary to replace the pressure gauge.
Are there any good and user-friendly watch manufacturers?
