Westech Industrial Ltd is excited to announce the launch of our partner Vaisala's pioneering optical inline process refractometer series for industrial liquid measurements. The series is designed to provide accurate and reliable measurement of refractive index, concentration and density of liquids in a range of industrial applications. The Vaisala optical inline process refractometer series ...
Gastroesophageal reflux disease (GERD) is a highly prevalent disease. It affects about two thirds of adults in the U.S. at some point in their lives and accounts for greater than 4 million physician visits every yearl?. The so-called typical symptoms of GERD consist of heartburn, regurgitation and dysphagia. Cough, wheezing, hoarseness or chest pain may be present and are termed atypical ...
Advantages of the laparoscopic approach include reduced postoperative pain and recovery time and improved cosmesis.17 Since its introduction, the laparoscopic approach has been modified to reduce even further the number of incisions and trocars needed, while maintaining operative efficiency and good outcomes.34 This report describes the use of a totally intracorporeal retractor ...
Affected by metal artifacts, metal retractors or drilling devices or ultrasonographic probes can cause electromagnetic navigation errors. ...
In our last blog, we discussed how plant and operation managers are searching for ways to manage the flow energy in their facility to cut costs and increase their process efficiency. After the purchase decision is made, correct installation and calibration are the next steps to maintaining the equipment over the lifetime of the product and lowering the cost of ownership to increase the cost ...
Sierra’s Solution for Steam Flow Measurement- InnovaMass 240i/241i -Provides Proven Accurate Steam Flow Measurement Multivariable: mass flow rate, volumetric flow rate, density, pressure, temperature Accuracy of up to 0.7 percent of reading; 30:1 turndown Dynamic density calculation improves steam metering accuracy Hot-tap probe retractor for easy steam installation ...
We review the existing technologies for MISS surgery with regards to single-port devices, endoscope and camera, instruments, retractors and also the future perspectives for the evolution of MISS surgery. ...
Vortex sensor cutaway showing vortex principle of operation Advantages of multivariable vortex flow meters for steam measurement: Multivariable: mass flow rate, volumetric flow rate, density, pressure, temperature Accuracy of up to 0.7 percent of reading; 30:1 turndown Dynamic density calculation improves steam metering accuracy Hot-tap probe retractor for easy steam ...
The 241i insertion vortex can handle applications in pipes up to 72 inches (2M) in diameter and larger and has hot tap easy installation with an on board retractor. With the 241i, volumetric or multivariable measurement is possible with a single pipe insertion point, greatly reducing installation and maintenance costs. ...
Insertion vortex meters work well on very large pipes since they can be inserted into the flow by hot tapping with a retractor. Ultrasonic flow meter – Ultrasonic water flow meters use ultrasound to measure the speed of a fluid flowing in the pipe to measure volumetric flow. ...
Insertion vortex flow meters are ideal for large steam pipes with easy to use hot tap retractor. New technology and sensor advancement account for external vibration making the vortex flow meter even more accurate. ...
As you can imagine, due to high temperatures and pressures hot tapping in large pipes is an application that very few flow measurement devices can handle. Sierra’s new insertion retractor for the InnovaMass Vortex Flow Meter can be easily “hot tapped” into any size pipe with process connections from 150 lb. flange up to 600 lb. flange with its newly ...
The conventional approach to liver retraction utilizes a mechanical retractor that is held by an assistant and requires an additional subxiphoid incision and port An ideal method for liver retraction during laparoscopic upper abdominal surgery would lift the liver out of the operative field in a nontraumatic manner, providing adequate space for visualization and operation for as ...
Article Overview Traditional liver retractors require another wound for insertion, are bulky, and may cause iatrogenic liver injury. This study aimed to evaluate differences between three methods of liver retraction during laparoscopic Roux-en-Y Gastric bypass (LRYGB) and to compare novel liver retraction techniques with the traditional mechanical liver ...
