Leakage detectioon system for cooling tower

By | June 19, 2016

If water enters an oxygen lance from a leak in the cooling system, the results can be  catastrophic. Why take the risk, when simple means exist to avoid it.

Endress+Hauser’s highly accurate leakage detection system, designed to IEC 61511 and EN ISO 13849-1, detects the slightest signs of a leak, so that action can be taken before a situation becomes critical.

The flow rate and temperature at the inlet and outlet of the cooling circuit are measured using highly accurate flowmeters and rapid response temperature sensors. The temperature dependent variation in coolant volumes is then compensated using a highly accurate 4th degree polynomial. This allows very accurate and stable comparison of the inlet and outlet volume flow and thus the detection of extremely small leaks.
