The WMS-20 series consist of three individual wind monitor stations. The WMS-21 is a microprocessor based wind alarm station. It sounds an alarm buzzer and controls the operation of two electrical circuits whenever wind speed reaches either of two independent setpoints. An LCD display provides a readout of the measured wind speed and is also used to set the value of the setpoints. Self-contained relays for each alarm point can be used to actuate external devices such as air samplers or sirens.

The WMS-23 series monitors wind speed and direction. Each parameter is converted into a 4 to 20mA signal for use by process controllers or monitoring systems. Two versions are offered, WMS-23S measures wind speed only, while the WMS-23 measures both wind speed and direction.
