Abstract
A transmission meter (1) and a method for measuring the transmittance of a fluid, the meter (1) comprises an analysis chamber for passage of the fluid therethrough, means for receiving an electromagnetic source (9) within said chamber and three sensors (D1, D2 and D3) each configured to measure the output from said source (9), wherein each of the three sensors (D1, D2 and D3) are located at different distances from the source (9). The transmission meter may be used in a disinfection system either to measure the transmittance of the untreated water or to measure the transmittance of the water as it is purified.
