Abstract:

The Polish research centre has developed anemometers that are dedicated to measure airflow velocity and accepted for use in methane fields in underground mining plants with a danger of methane explosion.
The company is looking for partner concerned with constructing systems of atmospheric parameters measurement interested in commercial agreement with technical assistance.

Description:

In the anemometers, acoustic effects occurring in moving air have been used to measure air flow velocity. The generators of ultrasonic waves in a form of heads, operate alternately as a sender and a receiver of the anemometer. Measurement of air flow is performed by an ultrasonic time method. The anemometer operates also as signalling unit of cherease in air flow velocity or reversion.
Stationary anemometers for air follow speed measurement and allowable to use in dangerous explosive areas.
The technical data about this anemometers are:
Measurement range - 0÷5 ; 0÷10 m/s
Power supply - 10÷15V
Out-put signal - 0,4÷1,2÷2,0V
Energy consumption - 5mA
Intrinsically-safe performance - ExiaI
Rank of protection casing - IP54
Main elements of the anemometer are two ultrasonic sending-receiving probes placed in tubular guard. Ultrasonic heads in probes and electronic system provide transformation of a measured quantity and exposure of the measurement result. Measurement is made basing on time ultrasonic method. Measured quantity is a difference of ultrasonic wave (100 kHz) passage times in direction compatible with air flow and identical wave running in opposite direction. Such measurement is made 20 times per second. After processing of measuring signal the measured value is mapped at output by a continuos voltage or frequency signal. This signal equals overage value of air flow velocity for the last ten seconds.

Innovative Aspects:
- use of an ultrasonic method for measuring air flow velocity
- use of microprocessor systems for filtration of measuring signal and correction of characteristic

Main Advantages:
- measuring method and construction of the anemometer enable to measure low velocities of air flow (from 0,1 m/s)
- conversion and filtration of measuring signal allow better representation of air flow velocity, retaining high-speed reaction
