The most important thing to look for when replacing a pressure gauge for a fire sprinklers is Underwriters
Fire Sprinkler Pressure Gauges
Laboratory (UL) listed and Factory Mutual (FM) approved certification for fire protection sprinkler service.
If you maintain a commercial fire sprinkler system you may be familiar with The National Fire Protection Association (NFPA), which publishes NFPA 25, Standard for Inspection, Testing and Maintenance of Water-Based Fire Protection Systems. This 100-page document contains the rules, regulations and procedures for performing proper maintenance on systems. Read the rest of this entry »

WIKA Compound Pressure Gauge
I just got off the phone with a guy tasked with purchasing a compound gauge, but he didn’t know what it was or how it
was different from a standard pressure gauge. I get this call all the time, often from someone with an application that requires a compound gauge, but unsure how to select the right one. And no wonder, compound pressure gauges can be confusing and masquerade under a variety of names.
Here’s what you need to know:
Simply put, a compound gauge is a device that can display both positive and negative (vacuum) pressures. Read the rest of this entry »

Pressure Gauge Snubber
Did you know that a pressure snubber will protect pressure gauges from the harmful effects of vibrations generated in
a pressurized system? The pressure snubber works by evening out the rate at which the fluid or gas being measured arrives. While the snubber does not alter the pressure of the process, it will lessen the pulsation on the line, thereby improving the consistency of the gauge reading, and extending the effective lifetime of that particular gauge.

If you’ve never done it before, or somehow misplaced your old gauge, selecting a replacement pressure gauge can be an intimidating task. But don’t worry, I’ve created this quick and easy guide to walk you through the basics of selecting a pressure gauge.
STEP 1: PRESSURE RANGE
The first thing you need to know when purchasing a pressure gauge is what pressure range (pounds per square inch, or “psi”) you need. Since the accuracy of most pressure gauges is best in the middle third of a gauge, you should always select a gauge with a range that is about twice your normal operating pressure. For example, if you have an air compressor with a normal working pressure of 50 psi you want to select a gauge with a 100 psi range.
