Pressure gauge selection
Thread Content
Now we need to measure the pressure of a fluid in a pipeline; this fluid has a high viscosity, ranging from 20,000 to 30,000 cp. What type of pressure gauge would be suitable for this purpose? I have chosen a diaphragm pressure gauge – I’m not sure if that’s the right choice There is concern that stopping production for a while might block the pressure gauge port during production. Please give me some advice!
Diaphragm pressure gauges are suitable for measuring the pressure of media that are highly corrosive, operate at high temperatures, have high viscosity, tend to crystallize or solidify, contain solid particles in suspension, as well as in situations where it is necessary to prevent the measurement medium from coming into direct contact with standard pressure instruments, to avoid sediment accumulation, and where easy cleaning is required. So it was correct of you to choose a diaphragm pressure gauge.
Diaphragm pressure gauges come in a type that can be installed insertively. With insertion, there is no issue of pressure port blockage.
Thank you for the reply. I don’t need a digital display. Where can I buy one?
I completely agree with the view from the 3rd floor!
In addition to viscosity, the temperature of the medium and whether it is corrosive also need to be considered, and then a selection can be made accordingly. :)

For high-viscosity media, diaphragm pressure gauges are the preferred choice; however, due to the high viscosity, the temperature is usually high as well, so special attention must be paid to the issues related to their use. Furthermore, given such high viscosity, it is advisable to use a DN50 flange for the diaphragm pressure gauge, as this will result in greater sensitivity. If the temperature permits, plug-in types are the best.
