Model RL and TL Low Pressure Level Gages
Reflex and Transparent Flat Glass Gages – Pressures Up To 2400 PSI @ 100° F / 1780 PSI @ 600° F
Models RL and TL are low pressure level gages and are available in both single and multiple section types 1 through 9 with a one-piece liquid chamber. They are machined from solid bar stock of cold rolled carbon steel, stress relieved and assembled complete with drop forged steel covers, tempered borosilicate glass, gaskets, bolts and nuts, making the gauges resistant to thermal shock, heat, corrosion and abrasion. The liquid chamber is recessed to hold each individual gauge glass and gasket snugly, eliminating any possible movement by internal pressure. All bolts are properly spaced to ensure uniform pressure on the glass and gaskets, and are manufactured from ASTM grade steel. The gaskets used are of the finest quality, uniform in thickness and accurately die-cut. Our standard gasket material is compressed non-asbestos, but can be interchanged with alternate material depending on the liquid being used.
Construction Materials:
- Chamber: Carbon Steel, 304SS and 316SS
- Gasket Material: Teflon Lo-Flo, Non-Asbestos Compressed Fiber
- Window: Tempered Borosilicate Glass
- Options: Non-Frost Extension, Illuminators, Side Connections
Gauges are also available in Stainless Steel, Monel, or other alloys.
NCI does not recommend low pressure gauges for steam applications.
