Top 10 Reasons Why ProSafe-RS Safety Instrumented System (SIS) Is the Fastest Growing Safety Control System


Before ProSafe-RS, DCSs and SISs were typically supplied by different vendors and required extra engineering for the individual systems and interconnections. Furthermore, these systems were more difficult to master and operate as they had different interfaces. ProSafe-RS overcomes these hurdles through complete integration with Yokogawa’s CENTUM DCS – an industry first. The ProSafe-RS has been a global success since its debut in 2005, and is continually being improved.

ProSafe-RS has a unique and excellent dual architecture that is based on Yokogawa’s supremely reliable DCS technology. The SIS has a modular design, and dual architecture is implemented inside each module. And the modules themselves can be installed in a dual redundant configuration. This is controlled by the SIS and is fully transparent to the user. This approach maximizes both safety and availability, independently and simultaneously. This flexible system configuration makes it possible for the user to configure redundancy on a module by module basis, achieving the required availability in each system component.

A Better Solution for Open Channel Flow Measurement

Open Channel Flow Measurement
Open channel flow instruments require accurate measurement of the surface level of a liquid. A flume, channel or structure which has a known characteristic flow per measured head, together with the measured liquid level, accurately define the flow rate through the system.

Hawk Level Sensor
Hawk transducer for water applications.
Traditional systems use a stilling well and pressure level measurement system to measure the liquid level in the structure. Sedimentation and buildup will over time cover the sensing part of a pressure measurement system, leading to inaccurate or completely failed measurement. Buildup can also block passages to a stilling well, making any level measurement inaccurate or false. Regular cleaning of measurement systems and stilling wells is required to ensure operation.

Open Channel Flow Measurement The level instrumentation control manufacturer Hawk Measurement uses a non-contact Acoustic Wave sensor, positioned directly over the channel or flow structure, or above the stilling well if required, to provide maintenance free, reliable measurement of the liquid level.

Open Channel Flow Measurement The Hawk Sultan Flow instrument calculates flow through a range of standard measurement structures, and can also be individually tailored to a non-standard flow characteristic. Measurements are temperature compensated, and sensors are available covering a broad range of water, waste-water, irrigation and environmental monitoring applications.

Open Channel Flow Measurement Powerful measurement pulses keep sensor facings clean from moisture and condensation, ensuring maximum performance in all conditions. Continuous and switched outputs are included, as well as local totalizing of flow, and the ability to provide pulsing outputs per flow volume to external counting devices.
