Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of pressure gauges?
6 answers
Answers:
Brass gauges used on Ammonia systems, absolute pressure vs gauge pressure, not opening liquid filled gauges to Atmospheric pressure once installed. No gauge savers used where there is possibility of large surges or rapidly changing pressure. Gauges over sized for required measurement, non calibrated gauges used for release to service of product.
~Rish P, Technical Support, Christchurch, New Zealand
Gauge not suited for the amount of pressure utilized in the process.
~Stan, Sales L, General Management, Houston, TX
Need to perform calibration as per international standard.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using pressure gauges?
11 answers
Answers:
Study basic principles of gauges on line and have as much information available when requesting a gauge or gauge pricing from a vendor. Examples of info: Process media, Ambient and Media Temperature, Case style and type, Process Connection (1/4" or 1/2" NPT etc...), Wetted Materials (SS, Monel, CS), Lens type
~Ron D, Manufacturer, Lawrenceville, GA
Buying gauges based sheerly on what is cheapest may cost more in the long run (from a replacement cost due to failures), versus buying a high quality, high performance product like a McDaniel Controls pressure gauge initially.
~Stan, Sales L, General Management, Houston, TX
Yes, the pressure gauge is still used for local indication and work in harsh environment. Where ever one wants to see the local indication and cost effective instrument, pressure gauge is the ideal choice.
~Shridhar K, Marketing/Sales, Bangalore, India
Prefer to buy pressure gauges to which they can maintain and are not disposable. Costs are optimized.
~Rafael C, Technical Support, Chinandega, Nicaragua
Understand the application and why the measurement must be made and what is required.
~Rish P, Technical Support, Christchurch, New Zealand
Upgrade the technology to attract most reputed companies' use .
~Pratheesh Katpadi, Research & Development, Doha, Al-Khor., India
Refer to national standards and ISA guides
~Alan N, Engineering Consultant, Sydney, Australia
Select thre best and easily maintained.
~Ronald E, Electrical and Instrumentation Quality Engineer, Ras Laffan Industrial City, Qatar
Good understanding of the application,
~Technical Support/Services, Boyne Island, Australia
Glycerine filled seem to last longer
~Daniel T, Home inspection, El Paso, TX
read the coc carefully
~MOSHE SNEAR, Engineer, YAVNE, ISRAEL

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of pressure gauges?
8 answers
Answers:
Never attach a pressure gauge directly to a steam line, use a water filled isolation loop Aim for normal pressure reading to be around 50-75% of scale Cheap is often expensive in the long run, know accuracy, range and resolution required and process conditions before installation of gauge.
~Rish P, Technical Support, Christchurch, New Zealand
Be careful of the media temperature. If the media temp is higher than the gauge standard the gauge must either be piped away to lower the temperature or the use of a diaphragm seal is required.
~Ron D, Manufacturer, Lawrenceville, GA
Do not use the pressure each and every place in the plant. Where ever you would like to see the trend of pressure variation, the gauge should be used.
~Shridhar K, Marketing/Sales, Bangalore, India
Know the normal operation range as the maximum operating pressure can reach certain process.
~Rafael C, Technical Support, Chinandega, Nicaragua
Make certain that the gauge fits the application and process design.
~Stan, Sales L, General Management, Houston, TX
No, selection is based on the application , & reliability.
~Pratheesh Katpadi, Research & Development, Doha, Al-Khor., India
Don't buy cheap ones.
~Daniel T, Home inspection, El Paso, TX
Nothing specifics...
