Wireless instrument networking system

Viatran has released a wireless networking system (VNS), allowing centralised monitoring of sensors placed throughout oil and gas fields or other facilities.

The VNS system is made up of Viatran remote devices (VRDs) which gather information from sensors in the field. The VRDs relay the information to a Viatran hub (VHub). Each VRD will support up to three analog and two digital inputs. The VHub serves as a communication gateway for up to 10 VRDs.

The VRDs at the heart of the system can be either battery or solar powered. Typical battery life exceeds one year and battery condition is automatically monitored and reported. The VRDs are generally process or pole mounted.

The VHub receives messages from all the VRDs located in the field with which it is matched. With a typical transmission range of 1.6 km, the VHub maps the data received into assigned Modbus registers. The VHub can then pass the information to an attached flow computer, SCADA system or distributed control system.

The VNS has been designed for applications such as measuring gas and oil wellheads and pipelines, gas compressors and offshore and onshore oil rigs. Other applicable installations can include petrochemical processing plants and any other large-scale general processing plants.
