n: the flexible measuring or connecting element that is used to measure the liquid level in tanks by the automatic gauge method.

n: a system that automatically measures and displays liquid levels or ullage in one or more vessel tanks on a continuous, periodic, or ondemand basis.

n: in tanks with floating roofs, the vertical range in which the gauging measurements are not accurate.

n: a level metal plate attached to the tank shell or bottom and located directly under the gauging reference point to provide a fixed contact surface from which liquid depth measurement can be made.

n: a European term for the opening in the top of a container through which dipping (gauging) and sampling operations are carried out.

n: a European term for the point on the bottom of a container that the dip weight touches during gauging and from which the measurement of the oil and water depths are taken. The dip point usually corresponds with the datum point, but any difference in levels must be designated in the calibration table.

n: a European tem1 for gauging tape.

n: the apportioning of daily production rates to wells on a lease. Because there may be many wells on a lease, such production is apportioned on the basis of periodic tests rather than on the individual receiving and gauging of oil at each well.

n: I. a condition sometimes encountered in a pumping well when dissolved gas, released from solution during the upstroke of the plunger, appears as free gas between the valves. If the gas pressure is sufficient, the standing valve is locked shut, and no fluid enters the tubing. 2. a device fitted to the gauging hatch on a pressure tank that enables manual dipping and sampling without loss of vapour. 3. a condition that can occur when gas-cut mud is circulated by the mud pump. The gas breaks out of the mud, expands, and works against the operation of the piston and valves.

n: the low-pressure area of induction port in pump is filled with departed free gas，which will cause suck inproperly even cutout。

a gas retention device that permits gauging the tank without loosing gas to the atmosphere.
