Penberthy RHR & THR High Pressure Flat Glass Gauges give operators a direct, easy-to-read liquid level reference for high-pressure tank applications. These Penberthy high pressure gauges support petroleum, chemical, natural gas, and general process industries where teams need dependable visual confirmation.
The RHR model uses a reflex-style design for direct level indication through a single vision slot. Above the liquid level, the glass appears silvery. Below the liquid level, the glass typically appears dark or opaque. This contrast helps operators identify the gas and liquid interface.
The THR model uses a transparent-style design with vision slots on both sides of the chamber. This allows operators to view both the liquid level and process characteristics. As a result, THR gauges can support applications where colour, clarity, or interface visibility matters.
These high pressure flat glass gauges operate without electrical power. Therefore, they suit remote locations and applications where power failures cannot interrupt level visibility. They also support full vacuum applications and can verify other level instrument technologies.

Description
Direct Level Indication Without Power
Penberthy high pressure gauges provide a direct visual level reference at the vessel. Operators can see the process level through the gauge glass as liquid rises or falls inside the chamber. Because the gauge does not require electrical power, it can continue to provide local visibility during power interruptions.
This non-intrusive design also helps simplify level verification. It does not rely on density, surface turbulence, dielectric conductivity, or similar liquid characteristics. Therefore, facilities can process multiple liquids through the same vessel with fewer level visibility concerns.
RHR Reflex Gauge for Clear Interface Viewing
The RHR reflex model uses a single vision slot and prism glass to show level contrast. Above the liquid level, the prisms reflect surrounding light and appear silvery. Below the liquid level, liquid fills the prism area and creates a darker visual appearance.
This contrast helps operators identify the liquid and gas interface quickly. The RHR model suits high-pressure applications where teams need direct level indication and do not require liquid characteristic viewing.
THR Transparent Gauge for Liquid Characteristics
The THR transparent model uses a vision slot on both sides of the chamber. Light enters from the side opposite the operator, which allows the liquid to appear through the gauge. This design helps teams view the liquid level and observe liquid characteristics.
As a result, THR gauges suit applications where colour, clarity, or interface visibility matters. Illuminators can also support easier viewing in dark environments. In addition, optional shields can help prolong glass life in corrosive applications.
High-Pressure Design and Material Options
Penberthy RHR and THR gauges use a high-pressure flat glass design for demanding process applications. The design includes a recessed gasket seat in the chamber and cover. This supports reliable sealing and helps the gauge maintain pressure performance.
The gauges support pressure ratings up to 5000 psig at 100°F. They also support a published temperature range from -20°F to 800°F, depending on configuration. Tempered borosilicate glass supports standard high-temperature service, while aluminosilicate glass supports higher-temperature configurations where specified.
Flexible Configurations for Process Requirements
Penberthy high pressure gauges offer several configuration options. Teams can select reflex or transparent styles, glass sizes from 1 through 9, and one to four sections. The visible range can extend from 3.625 inches to 60.875 inches.
Connection options include end or side connections. Threaded, socketweld, and flanged connections can suit different installation requirements. In addition, available options include offshore coating, NACE materials, shields, Belleville washers, support brackets, scales, heat tracing, insulation jackets, and illuminators.
Applications
Penberthy RHR & THR High Pressure Flat Glass Gauges support direct-reading liquid level measurement in high-pressure process environments. They suit applications where operators need dependable local visibility, instrument verification, or a non-powered level reference.
