The gauge is always supplied with a manual screw-down isolation valve at the bottom connection, the 3/4” valve is available with an 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 valveless 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
