Model MG Liquid Level Transmitter Meets API Standards

The Level Plus Model MG liquid transmitter manufactured by MTS Sensors meets the requirements for the custody transfer standard as set forth by the American Petroleum Institute (API). The model MG level transmitter conforms to the Manual of Petroleum Measurement Standards’ requirements in Chapter 3, Section 1B, for inherent and overall installed accuracy of an automatic tank gauge. To validate conformity MTS tests 100% of all Model MG level transmitters on a state-of-the-art laser test bed that is traceable to the National Institute of Standards and Technology (NIST) standards. The maximum allowable nonlinearity is 1/16 in. to pass the laser test bed and to conform to the API custody transfer standard.

“As the world leader in magnetostriction, the accuracy of the Level Plus Model MG not only outperforms our magnetostrictive competitors, but also ultrasonic and radar technologies as well,” says Lee Aiken, Product Marketing Manager, MTS Sensors. “MTS continues to be a market leader in automatic tank gauging through investment in our core Temposonics technology, which is an advancement of magnetostrictive technology. These advancements translate into a highly accurate and easy to use level transmitter for our customers. MTS stands behind the performance of our level transmitters with certificates of conformity to AAPI standards, which state the inherent accuracy of a specific level transmitter. When MTS states a specification about accuracy, repeatability, and so forth, our customers know that we can meet it.”

The Model MG level transmitter satisfies the demand for a digital communications interface in the liquid level marketplace for vessels from 508 mm (20 in.) to 22,000 mm (866 in.) high. Outputs for the Model MG include Modbus, DDA (proprietary ASCII protocol), and FOUNDATION fieldbus. The Model MG level transmitter features 3-in-1 measurement of the product level, interface level, and the average temperature from one to 12 temperature points. This product feature lets customers use a single process opening, which eliminates the need for separate level and temperature transmitter openings and products. Designed for inventory control, the Model MG level transmitter is accurate to at least 1/16 in. at maximum length and can provide volume measurement from a 100-point strap table that the user loads into the transmitter. By incorporating the strap table into the transmitter, the user does not need to maintain multiple copies of the strap table or create the underlying formulas.

GAO Rolls Out Portable Data Acquisition Board

GAO Instruments has rolled out its 4512U 100K-12bit-16CH portable data acquisition board.

Portable Data Acquisition Board

This acquisition board is intended for field data acquisition, parallel data acquisition for more channels and time-phase sensitive acquisition. It achieves multi-point data acquisition at a reasonable cost and with high reliability.

This portable data acquisition board provides switchable triggering modes: manual, external and internal triggering. The internal triggers can be divided into triggering on rising or falling edge, and triggering levels are adjustable. The board is easy to install is hot-pluggable and automatically configured by the system. The device has a high A/D resolution, is integrated with 16-channel parallel synchronous acquisition and can be expanded to 256 full synchronized channels.

GAO’s portable data acquisition board includes pre-panel and post-panel: the pre-panel displays the acquisition state of channels while the post-panel provides a cascading interface of instruments.
