Gauge system inherently accurate

The Bubbler Gauge system is inherently accurate with a single transducer that is self-calibrated and is temperature compensated automatically.

The reading capabilities include mass, density, volume, height, temperature, temperature corrected volume, water level, programmable alarms, and all readings available on a network.

The system features remote access and interior display software. Centralized monitoring allows for control of the whole system and avoids human error in paper work, theft, and product transfer.

Timely reporting becomes a reality as the entire system can be seen at a glance, allowing immediate response and correction of errors before they compound. Record keeping becomes efficient with every transfer of every product being monitored and logged, the company says. High level alarms trigger the automatic shutoff avoiding the loss of product and cost of cleanup from spillage, the firm points out.

Communication is attained through a modem or satellite that corresponds with the central office. Visual representation of each tank at site and all relevant information for monitored tanks are displayed on an interior display that allows programmable, preset unmanned measurements, retrieved either locally or remotely. The system allows centralized inventory control and management.

System adds field ticket processing capabilities

New PetrisWINDS OneCall Rover is an application that works with the PetrisWINDS OneCall Screening Support System to bring locate ticket processing to pipeline operations.

Working on a Windows CE compatible device equipped with a GPS system, locate requests are downloaded from the OneCall System to the Rover hand-held.

Company locate personnel transport the Rover device to the field and enter the ticket data. Rover's on-board GPS system records the precise date, time, latitude, and longitude, providing a verifiable audit trail that helps satisfy governmental requirements. Data are uploaded automatically when Rover is reconnected to the OneCall system.

Techniques pull reservoir images, data from seismic

ThinMAN, a new broadband spectral inversion technique, allows the extraction of high-frequency images from traditional seismic data using proprietary technology.

The method can be applied to any seismic data, and the technique promises to produce a high-resolution image that can be tied to well control and other geologic information. The method has been tested on a number of data sets and is proven to reliably extract frequency content outside of the band of normal seismic data, the company notes.

Another new technology—LithPRO—is a multiattribute statistical inversion technique that can be used with a range of attributes to extract reservoir information from seismic data.

It has been designed to utilize traditional attributes such as reflectivity, impedance, and AVO attributes, along with more advanced attributes such as the isofrequency volumes generated by proprietary spectral decomposition technology. The technique provides an approach to statistical inversion of seismic data that can make a difference in a range of geologic settings where traditional mapping approaches are not effective, the firm says. The method is novel in that multidimensional operators that properly exploit vertical and lateral multi-

attribute correlations are defined for each output horizon. Thus, nonstationary statistical relations are readily handled.

New 1 ton ball screw actuator

A new addition to a lineup of ball screw actuators is on the market.

The new 1 ton capacity unit has a standard 23.1% efficiency rating and is available with top plate, clevis, or threaded end mounts.

Operation is simple. As you turn the horizontally mounted worm shaft, sliding contact is made with a worm gear inside the actuator housing. The worm gear is attached to a ball nut fitted with recirculating steel balls that makes translating contact with the ball screw reducing friction to a minimum and converting torque to thrust. The positive action of the low friction ball screw (which has also been heat treated for less wear) and nut design provides longer life at load and requires less power to achieve a specified thrust.

Actuators can be used individually, in tandem, or as part of a larger mechanical system. With lifts up to 20 ft, units come in many standard models, or can be custom designed for any application up to 50 tons.
