Resolution Infinite based on type of indicating liquid employed.
Input connection(s) 1/4” NPT tapped connection for typical tube fittings. Accepts pneumatic air/gas pressure input; high and low pressure inputs.
Materials of construction Formed channel indicator housing; brushed Stainless Steel (Type 304). Heavy plate glass window; acrylic plastic window available as special order.
Wetted parts 316 Stainless Steel liquid well and tubing
Indicating tube High strength, fully annealed glass (Pryex®)
Compressed air supply Compressed air supply that is clean dry and oil-free is required for operation of the system. Under normal operating conditions, supply pressure required is 55-60 psig.
