Triconex, a unit of Invensys Process Systems, recently announced a new communications module that meets today’s user requirements for open and flexible communications integration between safety instrumented systems (SIS) and distributed control systems (DCS) – without compromising either safety or security. The Tricon Communications Module (TCM) offers support for communications integration via industry-standard protocols. To date, the TCM incorporates an embedded OPC server and Modbus TCP/IP together with safe peer-to-peer and other standard Triconex features. In addition, the TCM supports full TCP/IP and routing functions for use with LANs and WANs. To help ensure safety, the TCM acts as a layer that isolates the Tricon safety system from control network and private LAN nuisances. The TCM itself is designed to degrade safely and recover gracefully. Support for redundant connections helps ensure that there will be no “loss of view” of the safety system from the DCS.

Flow Meter

Fluid Components International’s new CM Series Coriolis Flow Meters provide high accuracy flow measurement in larger line sizes up to 12 inches and flow rates to 80,000 lbs/min (2,200 metric tons/hr). They are well suited for applications in harsh, corrosive fluids requiring exotic materials-all now achievable for the first time in a standard product line. The CM Series design includes a leading edge Coriolis flow sensor and superior mechanical isolation to eliminate vibration effects, enhance measurement accuracy and minimize installation cost. The new CM flow sensor’s thick pipe wall construction can withstand pressures as high as 13,000 psig (900 bar). In applications where there is a danger of the fluid solidifying into a no flow state or where heat is needed to maintain flow, the CM series employs an internal heat tubing array, which improves efficiency and saves space over the typical bulky external heat blanket technique commonly used by other devices.

Turck has introduced a new self-contained, fully programmable sensor that monitors both flow and temperature. The Digital Read Out (DRO) flow sensor is the latest addition to Turck’s extensive series of in-line flow sensors, and features a highly visible, three-digit display that can alternate between flow rate and media temperature. In addition to an adjustable on-and-off delay feature, the DRO allows the user to program setpoints specific to an application and has an adjustable filter to smooth out erratic flow conditions. DRO sensors are designed to operate with media such as water, glycol and other fluids. It is a solid-state device that operates on the calorimetric principle, resulting in a sensor with no moving parts that can break or become lodged in the pipeline. This technology, combined with the sensor’s in-line mounting, allows the DRO to perform in demanding applications without concern for flow restriction or application downtime.
