Abstract: An improved flow measuring device, such as a mass flow meter or mass flow controller, providing a high turn-down ratio as compared to prior art devices. In accordance with various embodiments of the invention, a flow sensor includes a sensor flow path that includes one or more restrictions configured to provide the sensor flow path with a non-linear relationship between a pressure drop across the sensor flow path and the flow of fluid through the flow sensor conduit. Such a flow sensor preferably achieves a high turn-down ratio by way of a variable bypass ratio that is directly proportional to the sensor tube mass flow rate so that the turn-down ratio of the mass flow controller will be ideally proportional to the square of the turndown achievable by the flow sensor conduit fluid sensing portion alone. In some embodiments, the restriction can be employed as a part of a fluid seal having an orifice and disposed between a flow sensor portion of a flow meter and a bypass portion of the flow meter.

Abstract: A method for installing risers so they extend from a FPU (floating production unit) to multiple subsea hydrocarbon wells of an oil field, which avoids damage to the pipe sections and that is economical. As pipe sections are connected to a near end (56) of a pipe string portion (68B-68D) that lies at the FPU, a tug boat (30) pulls the far end (65) of the pipe string toward a well head. Initially, a long pull line (34) extends from a winch (32) on the tug boat, in a double catenary curve to the far end of the pipe string. The winch is operated to shorten the pull line until the pipe string extends in a double catenary curve (60). Tension in the pipe string is maintained at a proper level during installation by maintaining the near end portion of the pipe string so it extends at a near end angle (70) to the vertical that continually lies within a predetermined range, such as from 3° to 12°.

Abstract: A system for dispensing cryogenic liquid to a use device includes a bulk storage tank providing LNG to a sump containing a meter submerged in LNG. A temperature probe is also submerged in the LNG. A dispensing line is positioned between the meter and dispensing hose and includes a dispensing valve. A drain line bypasses the dispensing valve and features a check valve so that LNG trapped in the hose after dispensing is returned to the sump due to pressurization by ambient heat. A capacitance probe is submerged in the LNG in the sump and provides a dielectric that is compared by a microprocessor with the dielectric for pure methane at the same temperature to determine the purity of the LNG. An approximate linear relation between density and dielectric may be used to determine density and mass flow for the LNG from the measured dielectric. Alternatively, a density compensation factor based upon the dielectrics may be calculated and applied to the density of pure methane to obtain the density and mass flow of the LNG. A further alternative embodiment substitutes a compensating meter for the capacitor and the equations for the resulting two meters may be solved to determine density and mass flow for the LNG.
