Questions

Question

Can a Slack tube manometer be used for water pressure?

Answer

That style of manometer is to be used with air/gases only. If you need something that reads water pressure, you would want to use something like our Series 490, Series 490A or Series 1211/1212.

Question

Model 1212. How much fluid mixture is required? What is the best method to fill this unit?

Answer

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.
