Gauge Hatch (Non-atmospheric, sampling slot dip hatch)

Model No: 220

Storagetech’s Non-atmospheric Sampling Gauge Hatch, model 220, provides access to bulk storage tanks while protecting personnel and the environment during the processes of taking product samples, temperature, and gauging the depth of product and residual water.

Designed specifically for use with volatile and hazardous liquids, the loss of liquid product and noxious vapour is minimized due to the construction of the hatch chamber. The unit is an assembly of two chambers, with upper and lower sections being isolated by a manually operated sealing disc. Entry to the Sampling Gauge Hatch is through a lockable closure in which a bayonet fitting will allow entry for the sampling, and temperature devices, and depth measuring tape. Considering its closed system Storagetech slot dip device is suitable for Nitrogen Blanketing (N2 Blanketing).

With the lower chamber sealed, the closure can be opened and the measuring or sampling device inserted through the bayonet fitting and loaded into the top chamber. The closure is sealed before the chamber sealing disc opened. The collection device descends into the tank under the control of the operator at the top of the tank and collects the sample or information required.

The operator withdraws the device into the top chamber and seals the two chambers. The closure can be opened and the sample and information retrieved. The bayonet fitting entry is plugged, and the closure shut and locked.

The Storagetech Sample Gauge Hatch is used in the petroleum, petrochemical, chemical, and in many instances replaces the use of conventional gauge hatch. It must be installed on a flange at the top of the tank in the horizontal plane.

Matching connectors for the closure bayonet fitting can be supplied also by Storagetech.
