Safeguard Armored Tubular Liquid Level Gages

The Safeguard Tubular level gage (shown with valves) is an armored gage assembly that is about one-tenth the cost of an armored

flat glass gage. Safeguard is perfect for applications where product spills are not acceptable. Safeguard uses clear or redline gage glass protected by a steel or stainless steel U-channel with a clear polycarbonate see-thru window (with or without no-charge gage scale.) Made to order,Safeguards are available in lengths up to10-feet. Safeguard uses 5/8" or 3/4" OD steel or stainless steel stubs installed into a standard tubular gage valve set. This can minimize or eliminate steam attack of the gage glass in this area resulting in longer maintenance intervals.

To meet your budgetary and corrosion requirements Safeguards are available in all carbon steel, all stainless steel, and carbon steel with stainless steel wetted parts.

As a more economical alternetive for new construction, Model 9900 has all the features of the Safeguard with integral valves.


Yarway - Penberthy Boiler Trim Level Gages and Alarms

Penberthy Series 1A single probe alarm system represents the latest advancement in electronic level indication. Based on the conductivity probe technology now widely accepted in the industry, it was specially designed to meet increasing demand for a reliable, cost effective means of sensing water in various applications. The probe can be mounted directly to the pressure vessel or column. The probes are welded stainless steel HP (left) and LP (right)electrode with zirconia insulator (3000 psig @ saturation, up to 1200°F [207 barg @ saturation, up to 649°C]) or threaded stainless steel LP electrode with Teflon® insulator (850 psig @ 525°F [58 bar-g @ 274°C]). The Series 1A is a direct replacement for mechanical float switches. Local LED indication of water level provides either redundant or primary visual verification.

If you need a complete Color Port Gage and Water column assembly or a replacement electrode email us to get more information on all of Penberthy / Yarway’s line of Steam Water Boiler Controls.
