The Seetru Quickflex gauge is a flat glass level gauge which offer additional column protection than a tubular glass gauge.
Please note – the Quickflex gauge is not type approved for use with flammable liquids for shipbuilding applications, if you require gauge with marine type approvals please see the G31 Seeflex gauge and the G35 Seemag gauge.

Design

Gauge always supplied with manual screw down isolation valve at the bottom connection, the 3/4” valve is available with auto shut-off valve to seal the tank in case of damage to the gauge column.

Closed circuit design

The closed circuit design penetrates the tank wall at both top and bottom connections. The options for the top connection are either a manual screw down isolation valve or valve less tank return. The 3/4” screw down valve is available with auto shut-off.

Open circuit design

This is only allowable when it is possible for the gauge column to extend above the top of the tank by at least 100 mm. The upper end of the gauge can be supplied with an automatic safety vent valves or, alternatively, a pipe union connection. The automatic safety vent will allow air to pass, but will seal against a liquid level. In the case of the pipe union connection design, a 10 mm o/d steel vent pipe is returned to the tanks or into the tank vent pipe.

Tank calibration

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