The accuracy stated above can only be guaranteed if the parameters throughout the measurement are the same as
the ones the sensor was adjusted and calibrated for (e.g. medium type, medium temperature, tube size, tube material).

Please note:
– Qmin refers to the minimum flow value for which the accuracy is specified.
– Qmax refers to the maximum flow value for which the accuracy is specified.
– The given values describe the positive flow range, but are the same for negative flow values.
