Advantages of Sliding Gate Control Valves

Schubert & Salzer's sliding gate control valves are designed as an effective alternative to traditional control valves. The sliding gate valve controls liquid, vapor, and gaseous media precisely, quickly, and economically. The design is uniquely simple, but is intelligently built to handle complex applications that require precise control under taxing conditions. They are an excellent choice for a variety of media, including steam, liquids, and gases. 

How Sliding Gate Control Valves Work

A sealing plate with many crossways slots of equal height is fixed in the body at right angles to the flow direction. A moving disc with the same slot arrangement moves in parallel to the fixed disc, thereby changing the flow cross-section. The prevailing differential pressure presses the moving disc against the fixed disc and seals it. 

The machined orifices in the fixed plate or disc can vary in design, size, and configuration, determining the flow coefficient (Cv) and the flow characteristic of the valve. As the cross sectional area changes and the valve modulates, flow is broken apart, creating a variable field of area flow, which reduces energy and noise. The differential pressure creates a unique seal between the two plates, and when in the sealed position, an overlap of approximately 1 mm creates a leak-tight valve.

The Fox Thermal Mass Flow Meter Digital Advantage

Fox Thermal has the only thermal mass flow meters that bring the award-winning DDC sensor. This rugged device is a digitally controlled sensor that speeds up processing by interfacing directly with the flow meter's electronics. The unique digital sensor signal processing provides a technology platform for calculating gas correlations using GAS-SELECTX, a gas selection feature that means users can choose from menus of gases to formulate a unique gas composition in the field and at the push of a button.

This feature allows the user to avoid sending the flow meter back to the factory when the gas composition changes.  Fox is the only manufacturer that offers this feature without risking the loss of accuracy.

Another way to set the gas composition in the meter is by using the FT View software. This free and intuitive software can be downloaded and set up on a pc in a few short minutes. Once the flow meter is connected via the standard usb port, the software allows the user to easily configure metersettings view data charts, run simulations, log data, and test meter accuracy.

Introducing the Yokogawa Sushi Sensor: An Easy to Implement, Low-Cost, Rugged IIoT Solution Featuring Long-Distance Wireless Communication

Yokogawa Sushi Sensor

Yokogawa releases IIoT predictive asset management solution in North America for improved data-driven maintenance strategies to reduce downtime and enhance safety.

Unique online vibration and temperature monitoring solution with long range wireless networking and advanced analytics provides early anomaly detection in hazardous areas.

Yokogawa Corporation of America announces the release in North America of its Sushi Sensor, an OpreXTM Asset Management and Integrity wireless solution, with advanced AI analytics via GA10 software that make it ideal for IIoT plant asset management (PAM) applications. The solution addresses a growing need for efficient and effective online collection of equipment data across industrial facilities via wireless sensors for early equipment anomaly detection. The Sushi Sensor combined with AI GA10 software detects early signs of abnormal operating characteristics and transforms a reactive maintenance process to one which is proactive, intelligent, and condition based. By leveraging wireless technology, the solution reduces cost and logistical challenges for early equipment problem detection to deliver enhanced plant safety, reliability and profitability. With a free smartphone app for easy set-up and configuration, users can rapidly place hundreds of Sushi Sensor devices into service across a facility.

Oil and gas facilities lose up to 10 percent of annual production every year as a result of unplanned downtime, according to a 2016 study by ARC Advisory Group. Nearly 30% of senior executives, engineering, operations, and maintenance managers surveyed by ARC reported between 3-5% lost production every year from unscheduled downtime. The cost of equipment failure significantly impacts return on capital employed (ROCE) performance through lost revenues, high operating and maintenance costs (OPEX) and unnecessary capital cost (CAPEX) for remedial work, modifications and upgrades. More predictive and prescriptive asset management strategies are required to exploit the benefits of applying data and analytics to maintenance.

The Sushi Sensor, with LoRaWAN® (Long Range Wide Area Network) communication technology and advanced analytics from GA10 software, enables the digital transformation of rotating equipment asset management. Approved by testing and standards agency, FM Approvals, for operation in hazardous areas, the Sushi Sensor is a compact wireless device providing online vibration and surface temperature measurement in machines and process equipment. Via LoRaWAN®, a low power, wide area network with up to ten times the range of other IoT wireless networks, the Sushi Sensor efficiently communicates digitized measurements to Yokogawa’s advanced AI analytics environment. The solution involves easy installation/setup, excellent environmental resistance and monitoring versatility via on-premise servers or the Cloud.

New Product Alert: MTS Level Plus LevelLimit Liquid Level Transmitter and HI Level Switch

MTS Sensors has introduced the LevelLimit liquid level transmitter. The LevelLimit incorporates a magnetostritive level transmitter for inventory monitoring with an electrically isolated HI level switch for overfill protection. The sensor has the ability to monitor inventory levels with the added protection of a high level switch for those tanks that do not have openings for multiple sensors and for those applications that do not require a mechanically separate HI level switch. The initial launch of the LevelLimit includes an Intrinsically Safe approval from FM covering the US, Canada, ATEX, and IECEx.

Designed for use in oil lease tanks as well as bulk storage aboveground tanks, the Level Plus LevelLimit features 5-IN-1 measurement of the product level, interface level, temperature, volume and an integral HI level switch. The HI level switch uses a Digital I/O signal to trigger alarm functions in a PLC or remote RTU. The switch is equipped with a manual test method that allows for periodic checks of proper alarm function. A Modbus signal is used for conveying all of the inventory data including up to 16 temperature points. The LevelLimit’s ±1 mm inherent accuracy makes it highly suitable for monitoring inventory levels of refined fuels, crude oil, fuel oil, ethanol and other valuable liquids.

The LevelLimit transmitter is available with a flexible hose that is available for tank heights up to 22m (72.2ft.) or with a rigid pipe for those tanks 7.6m (25ft.) or less. The standard process connection is a 4” NPT fitting designed for installation on oil lease tanks. Additional process connection types and sizes will be released soon. All of the wetted parts for LevelLimit are 316L SS (1.4404) with additional materials to be released soon.

MTS Sensors liquid level transmitters present customers with a "set it and forget it" solution. Once installed and calibrated there is no requirement for scheduled maintenance or recalibration work. As a result operating costs can be significantly reduced.
