Questions

Question
We are using a Durablock inclined manometer with a range of 0-0.25" of water. What is considered a normal response time to steady state? We are seeing times of 1 minute whereas the manual states 'a few seconds'. Gage fluid is well beyond the recommended three years. Do I need fresh (i.e. new) gage fluid? My supply is as old as what's in the manometer.
Answer
The manometers have a response time that is dependent on the length of tubing, so a response time of a minute is not uncommon. You may want to check your fittings to make sure there is not a clog present. The gage fluid has a lifespan of three years before the inherent properties start to change, so it is suggested to replace it. A one ounce bottle of fluid is p/n A-101.
