internal temperature sensor / 2 digital inputs / 1 analogue input / 1 NTC input
The air flow meter PCE-WL 1 is an ideal tool to measure and store the wind speed over a long period of time. The battery operation enables you to use the air flow meter for mobile applications. Since a wind power station is an expensive investment, you usually want to know what profits it will generate in advance. The air flow meter PCE-WL1 helps you determine these profits. The measurement data is recorded on a microSD memory card. The user can select the desired measurement rate (1 min or 10 min) when setting up the device. The air flow meter creates a report file once a month which is saved in *.csv format. The *.csv files stored on the microSD memory card can be transmitted to a computer via the RS-232 interface and can be analyzed there by using Excel. This way, it is possible to determine the optimal location for a wind power station. The device comes with two digital inputs where you can connect sensors with isolated contacts, Hall effect devices, TTL signals and output SO-signals. The anemometer has an analog input to record the wind direction, as well as a NTC input for an external temperature sensor. The air flow meter is configurated via an RS-232 port. This option also allows real-time data transmission. The cup wind sensor of the air flow meter does not need to be aligned with the wind direction to measure the horizontal wind speed. The dynamic and supportive materials are made of plastic and ensure a safe and almost maintenance-free condition. The resolution of the wind speed measurement is 0.4 m / s. The L-bracket for mounting that is included in the delivery easily holds the wind sensor. The wind sensor also comes with a built-in heater (needs an external power source), which warms up the device for an optimal performance at low temperatures in winter.
