Anemometer mobile mining

Direction to use:
The anemometer can be used to monitor the flow rate in the atmosphere of the working area of the mine.

Principle of operation:

  • The operation of the anemometer is based on the thermometric method. 
  • The essence of the measurement method lies in the relationship between the heat loss of a continuously heated body (platinum thermistor) and the flow rate in which this body is located.

Features of this measurement method:
- wide range of speed measurement;
- high performance;
- maintaining high accuracy and stability of work throughout the entire service life.

Functions and features of the anemometer:
- flow rate measurement;
- indication of the ambient temperature;
- reading abs. ambient pressure;
- calculation of volumetric flow;
- storage of measured and calculated data in the nonvolatile memory of the anemometer;
- small dimensions and weight;
- protective case for carrying the anemometer;
- telescopic tube up to 84 cm long for measuring flow velocity in hard-to-reach places.
