Abstract: This invention relates to a measurement tool, and in particular to a measurement tool for use in determining the density and/or viscosity of a stationary or moving fluid. The measurement tool has been designed for use in borehole applications during the location and exploitation of oil and gas reserves. The measurement tool has a resilient pipe with a substantially uniform cross-section along its length, and the fluid is located within the pipe. The pipe carries an exciter which is connected to a signal generator, the exciter and signal generator being adapted to impart transverse and/or rotational oscillations to the pipe. Measuring the frequency of the oscillations can be used to determine the density and/or the viscosity of the fluid within the pipe.

Granted: 2014-06-03
Abstract: A gas regulator includes an actuator, a valve, and a cartridge disposed within the valve to advantageously direct, or "boost," fluid downstream and away from the actuator under normal operating conditions, thereby increasing the operating efficiency of the regulator. The cartridge includes a first portion with a first diameter and a second portion with a second diameter that is greater than the first diameter. During normal operation, the first portion receives a valve disc of the actuator within generally tight tolerances such that the valve disc and the cartridge restrict fluid communication between the valve and the actuator. This directs or "boosts" the gas toward the outlet of the valve. Additionally, during a relief operation, the second portion of the cartridge receives the valve disc to allow the free flow of gas to the actuator.
