New three-beam ultrasonic flowmeter
A new generation of three-beam ultrasonic flowmeters is designed for a range of heavy crudes to liquefied petroleum gases.
Combined with digital signal processing, the third beam helps improve accuracy and repeatability of the measurement, the company points out.
Measurement is independent of conductivity, viscosity, temperature, density, and pressure.
The unobstructed ultrasonic flow sensor, with smooth surface finish, inhibits any material buildup. This, combined with no moving parts to wear out, provides for years of maintenance-free service, the firm notes.

New landing string control system
A new landing string control system is designed to enhance the latest generation of landing string technology for completion and intervention operations.
Express7 has been designed for use in deep or ultradeep water.
Combined with this firm's enhanced landing string assembly, it promises operators with a solution for completing deepwater subsea wells.
The system uses the simplex or direct electrohydraulic control method but also deploys the features and benefits of multiplex for data acquisition.
A feature of this system is simplicity, because there is no requirement for complex subsea electronics or power supply.
Other features include reliability and reduced downtime, lower deployment and production costs, and the retention of hydraulic backup via pilot lines, independent data acquisition and project interchangeability.
Express7 also allows for downhole storage of control fluid required to operate subsea valves.
By storing the fluid as close to the valves as possible, this helps ensure that the system meets protocol standards and will achieve system shut-in or well closure and disconnect within 15 sec.
Express7 is designed to operate in water depths of as much as 10,000 ft with a maximum external pressure of 5,000 psi, a maximum working pressure of 10,000 psi, and a maximum working temperature of 300° F.

New flush diaphragm pressure transducer
This new flush diaphragm Model 355 pressure transducer is a rugged, one piece, stainless steel unit suited for operations that involve spraying or application of sealants, paints, coatings, or other congealable media that can clog conventional pressure ports.
The internally amplified unit delivers 4-20 ma or 0-5 v DC output, ready for PLC or instrument interfacing.
It's available in pressure ranges of 0-500 psi through 0-5,000 psi and delivers ±0.5% full scale accuracy.
It has an operating temperature range of –40 to +200° F., with a standard compensated temperature range of 60-160° F.
The unit measures about 2.6 in. in length and has a 7/16 in.-20 UNF straight thread pressure port.
The Model 355 is all welded and hermetically sealed for reliable performance in corrosive environments.
Electrical termination is a standard six-pin connector.

System aids remote medical emergencies
The VitalLink 1200 offers modern medical support for any organization or individual that operates in a remote location.
Created for nonmedically trained individuals, the VitalLink is easy to use and provides instant access to qualified medical personnel.
It is a remote medical monitor that can sendsomeone's vital signs in real time to a physician anywhere in the world for diagnosis.
Once the 22 lb backpack that houses the system is opened,and the two "on" switches are hit, audio and visual prompts guide the user in how to attach the medical leads to the patient.
The device immediately starts to monitor the patient and then automatically calls the predetermined medical center—whether it be a hospital, private physician, or medical department.
The call is made using either the internet, a land line, cell phone, or satellite phone, and then vital signs are transmitted in real time.
At the same time that thevital signs are being transmitted,the patient and the doctor can talk to each other as well as send live and still images.
The firm notes that one of its systems recently was installed on board a floating production, storage, and offloading unit off Angola, providing the crew with 24 hr/day medical advice from International SOS, which is a medical and security assistance company.
