The Refrigeration Liquid Level Gauge

The Seetru refrigeration liquid level gauges or indicators are specifically designed and proved for liquified refrigerant and other liquidified gases, they variously conform to BS4434 Part 1 1980 and BS4434 1989 and the Institute of Refrigeration safety code.

There are two versions, one with a tubular sight glass the other with flat reflex sight glass.

Tubular sight glass
The Tubular sight glass gauge is a compact robust and economical design.

The gauge is robustly constructed with a glass sight tube protected by an all round polycarbonate tube and a milled metal guard tube for strength. The metal guard tube supports the end connections against pressure, allowing flexible piping to be used to connect the gauge to the vessel.

Replacement of sight tube or maintenance is made easy by key drive positive sealing valves which allow the gauge column to be isolated and removed without interruption of the refrigeration process.

If the gauge is damaged the safety shut off valve operates automatically to prevent loss from the vessel.

Flat Reflex sight glass
The Reflex sight glass gauge is a highly robust versatile modular design.

This is a heavy duty gauge designed around modular components which enables the gauge to be configured to meet requirements exactly. The configuration is determined by a wide variety of industry standard fittings and connections.

Maintenance (or replacement of the sight glass)is made easy by key drive positive sealing valves which allow the gauge column to be isolated and removed without interruption of the refrigeration process.

If the gauge is damaged the safety shut off valve operates automatically to prevent loss from the vessel.
