Page 7: Introduction
Introduction Utilisation The OMC-150 anemometer is designed to measure wind speed and wind direction in harsh environments including potentially explosive atmospheres. Typical application areas are offshore industry, petrochemical industry, and transportation. All exposed parts are made in non-corrosive materials, therefore the OMC- 150 anemometer is ultimate suitable for marine environment. -
Page 8: Basic Specifications
1.5 Conditions of use. The OMC-150 anemometer is built to provide reliable measurement results under all weather conditions. Rain, snow, or other kinds of precipitation do not effect the readings. Further the OMC-150 anemometer is insensitive to noise, extreme temperatures, solar radiation, etc. -
Page 9: Description
The OMC-150 anemometer consists of a sensor body and a mounting bracket. Note that the mounting bracket, though it is sometimes referred to as OMC-157, is an integral part of the OMC-150 anemometer. The mounting bracket has a mast clamp and an electrical plug connector. This clamp is designed for mounting on a vertical pipe end. -
Page 10: Operation
See Appendix A: for a typical system layout. Note that the maximum length of the field cable, which runs from the junction box (nearby the OMC-150 anemometer) through the Ex zone to the OMC-158-2 interface unit, is up to 1 km (depending on the cable quality). -
Page 11: Safety
The OMC-150 anemometer is a Category 2 G device, certified for use in potential explosive atmospheres (gas explosion) in zone 1 and zone 2. The method of protection of the OMC-150 anemometer is intrinsic safety (Ex-i) according to EN-60079-0 and EN-60079-11. A risk analysis was performed on the mechanical construction of the instrument, both for operation during normal use and for anticipated faults, according to EN13463-1. -
Page 12: Required Personnel Qualification And Remaining Risks
The engineers that are handling the OMC-150 anemometer at the point of installation must be aware of the risks of working at height. Local Safety regulations on site must be adhered to. Adequate Personal Protective Equipment must be used where necessary. -
Page 13: Handling, Transportation And Storage
Once the installed, store the packing for later use (see section 5.3) 5.2 Long term storage When not in use, store the OMC-150 anemometer in a dry place. Note that this is required, as the system is only weatherproof when mounted in an upright position while the electrical plug is mated. -
Page 14: Installation
Ensure that the OMC-150 anemometer will be mounted on a location that is free from turbulence from obstacles. Plan the OMC-150 anemometer in a free area as far as practicable. For guidance on the best location refer to the WMO CIMO Guide . -
Page 15: Assembly Of Cup And Vane
(this may not always possible) The shafts of the OMC-150 anemometer and the inside of the cup unit and vane unit are conical. This enables fastening of the capped nut without the shaft turning along. -
Page 16: Alignment Of The Wind Vane
North by rotating the complete mast, thus aligning the wind vane to the North. Note that the accuracy of the wind direction reading of the OMC-150 anemometer depends fully on the alignment of the vane! -
Page 17: Electrical Installation
6.7 Electrical installation Connections The OMC-150 anemometer is provided with a plug to connect the sensor (through a junction box) to the field cabling. The anemometer has a 7-core signal cable with common screen wired to the plug. connector sensor internal... -
Page 18: Commissioning
Commissioning Commissioning procedure It is impossible to calibrate the OMC-150 anemometer in the field. However, the following procedure makes sure that the installation was successful. 1) Check the connections 2) Install the interface and (if applicable) the display instrument. Normally the OMC-150 anemometer is powered through the interface unit. -

Page 21: Maintenance
Take care not to damage the cup unit or the vane blade while mounting or disassembly. The shafts of the OMC-150 anemometer and the inner side of the cup unit and vane unit are conical. After removal of the capped nut and washer or O-ring, it might require a careful tap to loose the cup unit or vane unit from its shaft. -
Page 22: Recalibration
9.3 Recalibration If the OMC-150 anemometer is included in a calibration program, the recommended calibration interval is 2 years. If required, you can adjust this interval. Calibration of wind speed sensor is only possible in a wind tunnel. Observator instruments b.v. provides calibration services. -
Page 23: End Of Operational Life
10 End of operational life If the OMC-150 is at the end of it operational life, it must be disposed in accordance to the local regulations at that time. The main materials of the OMC-150 anemometer are stainless steel. Manual | OMC-150... -
