Determination of Wind Velocity and Wind Direction with the PCE-WL 1 Wind Recorder


Source: PCE Instruments

PCE Instruments UK has recently added the new PCE-WL 1 wind recorder to its range of products. The PCE-WL 1 wind recorder is a measuring instrument which measures and records wind velocity over a long period. Thanks to the power supply via batteries, it can be used in mobile applications.

Since wind power energy is a cost intensive investment, it is important to know how much wind energy is to be expected, in advance. This task is undertaken by the PCE-WL 1 wind recorder. The measured data is stored on an SD card which is connected to the computer easily. The storage interval can be adjusted in advance and reaches from 10 seconds to 10 minutes. In addition, the wind recorder creates a CSV file in ASCII format once a day or once a month. This file can be transferred to the computer and analysed.

The PCE-WL 1 also has an RS232 interface where a USB cable can be connected to. On the two digital inputs the WL 1 offers: potential free contacts, Hall-effect switches, TTL signals and S0 outputs can be connected. Furthermore, the wind recorder has an analogue input which helps the user to determine the wind direction. The wind sensor, which is part of the delivery content, is compactly constructed and makes it possible to measure the horizontal air flow direction independently. The main and dynamic material is made of plastic and guarantees a secure operation which is nearly maintenance-free. The resolution of the measurement is 0.4 m wind way. With the help of an enclosed mounting angle, it can be installed comfortably and safely. If an according power supply is available, the integrated heater makes the wind recorder an almost trouble-free winter operation (this cannot be ensured by the wind recorder).

With the PCE-WL 1 wind recorder, PCE Instruments UK offers a new decision support device which helps to find out if a wind energy plant is profitable or not.
