Gauge Hatches

Pedal Operated & Lockable Gauge Hatches

Application

Gauge hatches allow easy access to atmospheric liquid storage tanks for manual level measurement (dipping), temperature measurement and sampling. They are available in 'un-lockable' and 'lockable' versions.

Principle of Operation

Gauge hatches provide tank access where manual level gauging, temperature measurement or sampling is required. The safety pedal allows the operator to open the gauge hatch whilst remaining 'hands free' to carry out required measuring.

Features and Benefits

  • Robust construction to cope with regular use.
  • Range of sizes and materials to suit a wide range of applications
  • Non-sparking feature, provided by the use of a PTFE or Nitrile rubber insert
  • The cover is designed with a condensation rim.
    This encourages liquid drainage from the surface to reduce the possibility of freezing.
  • Version with lockable handle and gas tight seal to 2.5 psig
  • ATEX approved to directive 94/9/EC

Application

This product is a lockable combined hatch and free vent in one fitting. It is designed to allow easy access to tanks for measuring whilst allowing the tank atmospheres and vapors to flow freely in-between sampling.

Principle of Operation

A combination gauge hatch and free vent provides tank access by swinging back the hatch cover to allow manual level gauging, temperature measurement and sampling when required. Whilst venting the opening is fitted with a wire mesh screen to prevent the ingress of foreign matter.

Features and Benefits

  • Robust construction to cope with regular use.
  • Range of sizes and materials to suit a wide range of applications.
  • Non-sparking feature, provided by the use of a PTFE or Nitrile rubber insert.
  • Large streamlined mushroom type weather hood to permit maximum flow.
