Technical data
10.1 Input
10.2 Output
10.3 Performance characteristics
Measured variable
Total chlorine
Free chlorine (Cl
2
(dissolved), HOCl, OCl
-
)
Bound chlorine (chloramines)
Organic-bound chlorine (e.g. cyanuric acid derivates)
Applications
Drinking, industrial, process, cooling water, fresh water and sea water for swimming
pool and whirlpool treatment
Measuring range
0.1 ... 10 mg/l
Slope
110 ... 120 nA/(mg/l)
Output signal
0 ... 5 µA for the connection to the transmitter Liquisys M CCM223/253
Response time
T
90
approx. 60 s (as concentration rises and falls)
Resolution
0.01 mg/l
pH range
5.5 ... 9.5
pH dependency: jump from pH 7 to pH 8: approx. -10 % for free chlorine
Conductivity range
0.03 ... 40 mS/cm
Temperature range
5 ... 45 °C (41 ... 113 °F), no quick changes in temperature allowed
Pressure
Medium in the CCA250 assembly: max. 1 bar (14.5 psi)
Flow
optimum:
40 ... 60 l/h (10.56 ... 15.84 US.gal/h)
minimum:
30 l/h (7.92 US.gal/h)
maximum:
100 l/h (26.40 US.gal/h)
Medium velocity
optimum:
20 ... 30 cm/s (0.7 ... 1.0 ft/s)
minimum:
15 cm/s (0.5 ft/s)
maximum:
50 cm/s (1.6 ft/s)
Cross sensitivity
Oxidising reagents e.g. bromine, iodine, ozone, chlorine dioxide, permanganates
result in false positive results.
Reducing reagents like sulphides, sulphites, tiosulphates, and hydrazine result in false
negative results.
Service life of membrane cap
Typically 3 - 6 months, depending on water quality
