Meteorological specialists, Biral is attending the InterMet Asia show in Singapore next month to showcase its new and popular meteorological products.

Biral’s Marketing Director, Nathan Neal, will be at the show demonstrating a wide variety of meteorological equipment. These are the BTD-300 Thunderstorm Detector, VPF-730 and SWS-200 Visibility & Present Weather Sensors, RWS-20 Road Weather Sensor and the brand new BTD-350 Thunderstorm Detector.

New BTD-350 Thunderstorm Detector

With its rugged design for marine applications, the BTD-350 Thunderstorm Detector, following the current BTD-300, is a standalone sensor that detects the presence of all forms of lightning to a range of 83 km. The BTD-350 is designed for marine applications, where severe weather, salt water corrosion and platform vibration produce a challenging environment for environmental sensors. The metalwork is corrosion-resistant stainless steel and aluminium, further protected by marine-grade paintwork. Reinforced antenna supports prevent damage from excessive vibration.  This design has been extensively tested in the laboratory and meets European marine vibration, marine radio interference and marine corrosion standards.

BTD-300 Thunderstorm Detector

The company’s BTD-300 Thunderstorm Detection system uses a new technology detection system which has significant benefits for the wind energy sector. The system has the ability to detect all forms of lightning within an 83km radius, including warning of potential overhead lightning. The equipment is immune to man-made false alarms making it highly reliable in safety critical situations such as during turbine construction and maintenance.

VPF-730 Visibility & Present Weather Sensor

As Biral’s most corrosion resistant design, the VPF-730 provides accurate visibility and present weather measurement and has been specified for many installations due to its efficiency, reliability and performance. The sensor is a compact and robust package which makes it particularly suitable for controlling aviation obstruction lights on wind turbines. Its exceptionally long service life (15+ years) makes it ideal in coastal or off-shore locations where the local conditions can be severe.

SWS-200 Visibility & Present Weather Sensor

The SWS-200 is designed for use in applications where accurate and reliable visibility measurements are required with the addition of WMO 4680 present weather codes. The sensor measures Meteorological Optical Range (MOR) as well as reporting the presence of liquid and frozen precipitation. A feature of Biral sensors is their ability to report precipitation intensity according to a range of national standards. The unique backscatter receiver gives the SWS-200 unparalleled abilities in distinguishing frozen from liquid precipitation. This additional meteorological information can be key to the safe operation of wind turbines in harsh winter conditions, where icing of the blades can be a serious problem affecting the efficiency of energy generation.

RWS-20 Road Weather Sensor

Also at the show is Biral’s RWS-20 visibility sensor, which has been designed specifically for the harsh road-side environment. The design is based upon the proven and very successful SWS range of sensors, sharing many of its advanced technical features. The new design uses a compact forward scatter measurement principle and remains accurate in all weather conditions, ensuring local light sources, headlights or flashing signs do not impact its operation or reliability.
