A method of detecting a flow blockage in a pipe comprises the steps of:
(a) arranging a fluid flow along the pipe, the pipe being in fluid communication with a pressure sensor;
(b) configuring the pressure sensor to measure a pressure within the pipe;
(c) recording a plurality of measurements of the pressure within the pipe;
(d) sampling 'n' successive values of the pressure within the pipe;
(e) performing an analytical test on the 'n' successive values, the analytical test producing an output value, the output value being representative of a variation in the individual ones of the 'n' successive values;
(f) comparing the output value to a pre-defined threshold value, the threshold value being indicative of a lack of variation in the individual ones of the 'n' successive values; and
(g) if the output value is less than the threshold value, generating an alert to thereby provide a user with an indication of the presence of a flow blockage in the pipe.. |
