SICK has launched ultrasonic air velocity meters for continuous air flow measurement in mining.
Used in ventilation applications, the device is designed to replace the often manually intensive and time consuming process using an anemometer.
The FLOWSIC60 provides automatic air flow, both air supply and exhaust air measurement.
It can measure air velocities ranging from -10 to 10m/s, SICK says.
The ultrasonic measurement principle operates wear-free and continuiously measures air velocity across entire tunnel cross sections, ranging from .5 metres to 8.5 metres.
It manages to operate wear free as it uses no mechanically moving parts and is largely resistant to contamination.
This means it is nearly maintenance free.
Additionally, an integrated self diagnostics system continuously monitors the equipment's status and warns against incorrect measurements.
According to the company it offers reliabiilty in harsh and demanding mining environments as well as saving time.
It is built from stainless steel components connected to each other by metal-reinforced sensor cables.
Importantly, the FLOWSIC60 is intrinsically safe, allowing for its use in coal mines and other potentially explosive environments.
It has been rated IECEx, with the equipment protection level (EPL) "Ma".
