Fluids for Dwyer Products Gage fluids in the 1 ounce size are furnished in unbreakable plastic dispenser type bottles. Use only Dwyer fluids in Dwyer gages. Red gage fluid, blue gage fluid, and fluorescein green color concentrate.
- 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.
- 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.
- Model 1212. How much fluid mixture is required? What is the best method to fill this unit?
- A 1 oz bottle of A-126 Fluorescein green color concentrate is added to a quart of distilled water. Remove a tubing connector from the manometer and pour the mixture in to mid-point level. Shake the manometer to remove air bubbles and slide the scale so the zero mark is in line with the meniscus of the two fluid columns.
- can you dilute the red dye for the manometer with distilled water?
- The red gage fluid has a specific gravity of .826. If you dilute it with distilled water you will change the specific gravity and it will not work in instruments that require the red gage fluid.
