Onshore unconventional drilling is commonly used in the extraction of oil and natural gas today. There are an increasing number of multi-well pad type drilling programs in most of the active plays. Different drilling technics are used to decrease drilling time, lower environmental impact and to improve initial and estimated ultimate recovery.
Gas flow data calculated by an RTU can be sent back to a transmitter using the two-way communications capability of FOUNDATION fieldbus.
One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.
Operators must receive diagnostic information before a line block leads to a malfunction. Yokogawa provides predictive diagnostics based on trend analysis of the blocking factor, which improves maintenance efficiency and reduces maintenance costs.
Level transmitter configuration can be very time consuming. DPharp transmitters with advanced software functionality eliminate this time consuming task. With maintenance shops getting smaller, finding equipment that allows us to do more with less becomes a priority.
STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.
To make the most of the advantages of GPRS, Yokogawa's STARDOM FCN/FCJ intelligent RTUs and FAST/TOOLS SCADA package have several functions that reduce the number of packets that must be sent. This dramatically lowers communication fees.
PID is an acronym for proportional band, integral and derivative. This control action allows a measurement (process variable) to be controlled at a desired set point by continuously adjusting a control output. These control parameters act on the error or deviation between set point and process variable.
Yokogawa first introduced its renowned SUPER CONTROL™ in industrial controllers over a decade ago. This is a fuzzy logic alogrithm that eliminates overshoot from the desired set point and mimics the control expertise of the most experienced operator.
Flow Measurement of diesel fuel is a relatively basic flow meter application. However, measuring net fuel consumption on a 2.2 megawatt diesel generator is uniquely complex. The diesel engine requires a supply fuel line (fuel from the tank to the engine) and a return fuel line (fuel from the engine back to the tank).
Recently, several ARC Advisory Group analysts and management team members had a chance to sit down with the new Yokogawa President and COO, Mr. Takashi Nishijima, and several other top Yokogawa executives to discuss the company's burgeoning presence in the worldwide upstream and midstream oil & gas industry.
Vortex flow meters utilize a fluid phenomenon in which frequencies of Karman vortex streets released from a shedder bar inserted in a flow are proportional to flow velocities.
One solution packaged for production control systems today is a system comprising a PLC and SCADA (Supervisory Control and Data Acquisition) software that runs on a PC. An advantage of these systems is that they can be configured at considerably lower cost than systems that use dedicated devices as they use commercially available PCs.
Wireless technology has a long history, and it began around the time that James C. Maxwell theoretically predicted and then proved the existence of electromagnetic waves in the 1860s, and when Heinrich R. Hertz experimentally confirmed the actual existence of the electromagnetic wave in 1888.
Vortex flow meters have been appreciated by users as volume flow meters, which can, in principle, be applied to any flow measurement of liquid, gas, or steam. Volume flow measurement is enough for substances with small variations in density such as liquid.
In 1988, Yokogawa launched the ADMAG series of magnetic flow meters with increased resistance to fluid noise and zero stability, employing dual frequency excitation which was developed based on its long-cultivated technology for flow measurement. Since then, the ADMAG family has augmented its application range with such models as explosion-proof and integral types, and a capacitance type.
Since the release of the DPharp EJ series in 1991 and the DPharp EJA series in 1994, nearly 1.2 million of these transmitters have been operating all over the world. Recently, we have also developed the EJX series of even more compact, lightweight and advanced transmitters with multi- sensing capabilities built using silicon resonant sensor technology.
