Remote Monitoring, with alarm parameters, can be implemented into the cooling tower water treatment and condenser water system.
Consider the following applications which we have implemented for clients in the past:
The typical dosing equipment uses 4-20milliamp outputs for Bio hazard and other measurements. These signals can be scaled and display on most Energy Management or Building Management System. “Volt Free Contacts” are often available to signal an alarm when reading are high/low or chemical is out. Simple straight forward strategies for remote monitoring of your dosing equipment.
Town Water “top up” Metering.
Water meter vendors often provide a pulse output to the Building Management System (BMS) or Energy Management System (EMS). Various brands provide differing levels of accuracy and price. Water meters can be provided for large pipes to serve cooling towers, town mains, and similar.
Logging the condenser water temperatures entering and leaving the cooling tower and immediate picture of how effective the cooling tower is becomes apparent. This is ideal for considerations towards energy efficiency and also fault monitoring if the fan motors have ceased operation.
Fluid energy meters can be implemented at the tower or at the equipment or data room which is using the condenser water for cooling purposes. An integer is given by the High Level Interface (HLI) of the Fluid energy meter for logging. this integer is typically in Kilo joules which is calculated by the amount of water flow through the meter and the temperature entering and leaving the system, i.e. that amount of energy which has been transferred to the condenser water system to be taken away and expelled at the cooling tower.
