The G34B Reflex Gauge

Heavy duty liquid level gauge, suitable for high pressure/temperature combinations

Product Description

¹Maximum allowable operating pressure is dependent upon operating temperature and connection type, contact Seetru for full information

The G34 Reflex gauge is a heavy-duty (flat glass) liquid level gauge, suitable for high pressure/temperature combinations. The modular design is made up of compact and robust standard stainless steel precision cast elements.

Variations on the isolating valves ranging from quarter turn ball valves to heavy-duty hand wheel isolating valves complete with auto safety shut-off safety features are available in a number of flexible configurations offering end mounted, side mount, rear entry connections, with full centre-to-centre visibility can be secured with minimum overall length.

Column arrangements
The Reflex gauge is available with either a straight or staggered column and a choice of valve positions, to provide uninterrupted centre-to-centre liquid level indication. With the use of extension pieces, most centre-to-centre distance requirements can be achieved.

Valve options
A choice of isolation valves is available, either ¼ turn ball valves or CPI screw-down valves with ASV (auto shut-off valves). The ASV feature means that in the unlikely event that the glass is damaged the contents of the tank will not be lost. Also available are drain and vent valves.

Low-temperature applications
A polycarbonate frost shield is available which enables the gauge to be used down to -30°C subject to fluid suitability.

Electronic & digital readout
Remote reading systems and/or computer interface options provide a dual system with the advantages of both electronic and sight glass systems. Level alarms can also be implemented.

Where a measure of the precise storage volume is required an engraved scale plate can be provided marked with the capacity units.



Optimized Efficiency

Knowing your levels, pressures, and temperatures unlocks operational potential. Liquid-level indicators optimize processes, minimize waste, and prevent costly equipment failures, allowing you to operate at peak efficiency.
