In recognition of the need for alarm management as a means to improve operating reliability and safety at the world's operating plants, the Instrument Society of America has entered into agreement with PAS Inc. to re-publish an alarm management handbook.
Plant engineers and maintenance personnel are facing tougher demands in the construction, maintenance, and upgrade of processing systems. The performance expectations for these systems are much higher than they were just 10 years ago.
Why have so many plants switched from the higher accuracy load cell to level probes and site glasses to determine the contents of tanks? Let's explore the most common reasons and, in the process, examine the root causes of many vessel weighing dilemmas.
Signs of global warming are all around us, from melting glaciers to stifling heat waves. The 10 hottest years on record have all occurred since 1990, and scientists say global warming is likely to disrupt water supplies, flood coastal areas, increase disease outbreaks, and cause fragile lands such as alpine meadows and coastal marshes to vanish.
With an advanced U-tube flow sensor design, the new Model CMU Coriolis mass flowmeter is said to deliver more than twice the industry standard flow rate to set a new benchmark when compared to other Coriolis devices in its class.
S Series plastic impeller meters measure very low minimum flows of water, chemicals, and corrosives. These flowmeters are available in 3/8, 1/2, ¾, and 1 in. nominal pipe sizes with female NPT threads and have 6-24 Vdc pulse outputs that are compatible with many types of control.
The Model 231 Multi-Sense wet-to-wet differential pressure transducer is appropriate for users who need to monitor control pump differential pressures, chiller or boiler differential pressure drops, and flow measurement of gasses or liquids.
The new Sultan Flow is a rugged open-channel flowmeter suitable for real-time flow measurement of liquid materials. Featuring continuous 4-20mA output, alarm relays, failsafe relays, and serial data via RS-485 with Modbus, it measures head, flow rate, and flow volume and rate totalization.
The Ultramax Box LPU can be used as an upgrade to shell-and-tube heat exchangers in maximum pressure applications.
Flexisaddle LPD is 1-in. heat transfer media for regenerative thermal oxidizers. Promising low pressure drop and efficient heat transfer, it's suitable for applications where particulate buildup limits the service life of other media.
Kenics heat exchangers are high-performance thermal units offering maximum transfer rates even with highly viscous, difficult-to-process materials.
A new rental program for process heating systems has been set up to serve immediate customer needs or enable customers to evaluate system operation with their production processes prior to making a purchase commitment.
Colortrax striped fluoropolymer tubing can be used to identify chemical processes and fluid handling lines or other types of connections where quick tube identification is necessary.
Two types of polyethylene tubing a linear low-density formula and a co-extruded with ethylene vinyl acetate formula are made from non-toxic ingredients conforming to FDA standards.
