Monitoring of the water supply
WatchDog pro monitors and controls well systems and distribution systems. Process-optimised and low-cost alternative to complex PLC systems.
The requirements of the operation of water utilities are continually growing. Supply reliability and cost-effectiveness are more important than ever in the monitoring of the water supply. Today, the measurement, control and regulating technology has to be able to do more than just monitor threshold values and report operational disruptions. Now, information about the state of components such as pump motors, filter systems or emergency power units are important. Newly developed modular monitoring systems such as WatchDog pro from TELE offer here a ?lean? and low-cost solution ideally adapted to the processes.
For instance, the operating point of a pump can be monitored via the direct output measurement of pump motors in real time. Damage can thus be detected and avoided early on. Condition-based servicing is thus made possible ? as for instance recommended in the rules of the DVGW, the German Technical and Scientific Association for Gas and Water. Conventional programmable logic controls (PLC) are incapable of directly measuring the physical values required for this and of interpreting them. Rather, they have to 'translate' all the variables that are measurable in the water utility system, into analogous and digital signals and provide them via the respective operating system of the application software. The programming and installation effort for such comprehensive PLC systems is substantial and costly ? in particular with applications such as the monitoring of water utilities where only a transparent number of signals can be recorded. The modular monitoring system WatchDog pro from TELE offers a genuine alternative here. It facilitates the direct measurement and monitoring of many physical key ratios in the field. The system also ensures the forwarding of the data to the control level and assumes control tasks of a PLC in a process-oriented manner.

At a glance: central functionalities of WatchDog pro
Specifically with direct measurement, monitoring and storing of physical values, the flexible, modular system Watchdog pro offers clear advantages in comparison to conventional PLC systems.
WatchDog pro processes
- The signals for print, flow rate etc. using analogue inputs
- The signals from float, level and door switches etc. using digital inputs
In contrast to a PLC, the system offers the option of directly measuring voltage, performance, cosphi, temperature and current.
- Voltage: Network voltage, battery voltage, generator voltage
- Performance: Dry-run protection for pumps, run monitoring for ventilators
- Temperature: Temperature in buildings, switching cabinet, pump
- Electricity: Monitoring of heat registers or air-conditioning equipment for functionality
These measurement values can also be recorded on a memory card, depending on specifications.
Focus on the source: Monitoring of the well system
A central monitoring task in the water utility is the monitoring of the drinking water abstraction systems, such as springs and wells. The groundwater level is determined via a pressure probe, meters measure the water volume transported and the spillage or the flow rate; the ground water level is also recorded. Often, however, insufficient values are recorded to assess the condition of the well pump via remote monitoring. Although a frequency inverter often regulates the speed of the pump motor, the motor performance or the voltage are usually not taken into consideration here. Particularly here, however, the performance is a reliable indication for whether the motor is 'running smoothly'. WatchDog pro provides assistance here: Assembled directly at the pump, it measures the motor performance, forwards this key value via field bus or GSM/GPRS and also assumes, if necessary, the control of the pump. Compared to a conventional PLC, WatchDog pro is characterised not only by simpler processes; the system is also more cost-efficient in implementation. Another benefit of the WatchDog: With dimensions of just a few centimetres, it can also be installed in tight conditions, which are the norm in well systems.
Continuous monitoring
The knowledge about the condition of the well pump, and also its previous performance values, helps the operators when a regeneration of the system is pending. The WatchDog pro solution delivers valuable data material here on a memory card thanks to continuous recording. These empirical values offer the water utility a better basis for deciding whether and when the system needs to be overhauled. In addition to the well sub-system, there are also other possibilities of use for WatchDog pro as an alternative to large-scale PLC solutions. With water treatment systems too, the use of the process-optimised solution also pays off. Here, WatchDog pro can assume the monitoring and control of the system using the absolute physical values such as water pressure, differential pressure and water level.
Incident management: two-channel alerting system
With the incident management too, WatchDog pro offers benefits over conventional PLC solutions. The contingency management is ideally based on two redundant alarm systems that must work independently of one another. Usually, in the event of an incident and where there are no cable connections to a permanently manned control centre, the PLC sends out an alarm via GSM/SMS and/or via a telephone dial-up system to the respective stand-by personnel. The WatchDog pro monitoring is also designed for these channels. The decisive difference: WatchDog communicates via SMS directly with the control centre or the stand-by service, without the circuitous route via interference-prone software. In the process, the system transmits the signals measured directly at the system.
