The current market is flooded with many pressure gauge variants. Each type is designed to suit different applications, and that's why knowing how to choose the right one is crucial. Making the correct choice means understanding the factors that define the selection process. To find the right pressure gauge supplier, read through this post for an essential guide on finding one that will meet your needs.
Pressure Gauge Range
What's the ideal operating pressure for the required gauge, and what'll be the maximum reach of your system's pressure? Choose a gauge whose operating pressure lies within the dial's middle third. Besides, go for a range that's higher than the system's maximum pressure. However, if the gauge's operating pressure doesn't fall within the middle third, you may be forced to purchase an over-pressure guard.
Pressure Gauge Materials
Which types of materials under what temperature are going to pass through your gauge? Well, sanitary and regulatory limitations come into play here and must be duly considered. Besides, the gauge's operating environment is something you don't want to overlook. For instance, a pressure gauge with a stainless steel casing would be ideal for outdoor operation.
Accuracy and Size of Your Gauge
Where will you be installing your pressure gauge, and what are the current space limitations you must address? Does your supplier outline any specific accuracy requirements? Typically, smaller gauges are less accurate and can pose a challenge when taking readings, especially from a distance. For this reason, pressure gauge placement is crucial.
Pressure Gauge Mounting Style
When approaching a pressure gauge supplier, always inquire about its mounting. Mounting is vital, and common mounting styles available include:
- Lower Gauge Mount
- Back Connection/ Panel Mount with U-Clamp
- Bottom Connection/Panel Mount, Front Flange
- Centre/Lower Back Mount
- Rear Connection/Back Flange
All these and many other styles fit different scenarios depending on the type of application you are running. Your supplier must be able to advise you on the ideal option for your setup.
Pressure Gauge Connection Size
Before buying your pressure gauge from any supplier, always think about the connection size required for your processes. Some processes may need specific connections, including hydraulic, tube stub and high-pressure options. A reliable gauge supplier must be more than happy to offer any style that you'll require.
Pressure Gauge Options
Finally, determine whether your pressure gauge will experience vibrations or pulses during the process. Besides, consider the ambient temperature of the operational area. These two factors allow you to determine the type of fluid to add, whether to use a fill fluid or when to use a pulse reduction snubber on the gauge.
If you need help picking out pressure gauges, reach out to a local pressure gauge supplier.
